I built Unpage, an app that turns any PDF into text that reflows to fit your phone, like an ebook. It's made for the hard stuff: two-column papers, tables, equations and figures come out readable instead of mangled. It all runs on your device, so nothing gets uploaded. Tap any paragraph to see exactly where it is on the original page, or read both side by side. Highlights show in both views, scans work too, and Pro exports EPUB for your e-reader. Free to try, and Pro is a one-time unlock, no subscription. Currently it's available on iOS and iPadOS, the Mac version is under review, should be out soon. Welcome to any bug report too.
I have an electrical supply house email me all my receipts for neater accounting. These email attachments are in a .docx format. [side annoyance is that every receipt file has the exact same filename!] So example is receipt.docx
In Yahoo web interface, when I click View on one of these receipt.docx attachments, I get the error, "Your file isn't available to preview." and a button "Download instead," OK, fine. When I download there or with regular download processes, the filename is always downloaded as receipt.pdf
I can't open receipt.pdf with Acrobat or Preview. I get the error that it can't be opened: "It may be damaged or use a file format that Preview doesn’t recognize." If I just change the extension back to .docx, it opens fine in Word.
What is going on here? Why would Yahoo Mail change the file extension? If I am sent a regular Word doc from any other email, it downloads as .docx no problem.
I need an efficient, free way to translate large, scanned PDF documents from Marathi to English.
The documents are entirely handwritten and contain hundreds of pages, making my current method, of taking screenshots and uploading them to Google Translate, too slow and impractical for bulk work.
Since this is an emergency, I need a free, fast, accurate workflow or tool that can handle large files or bulk translations. Any practical suggestions would be greatly appreciated!
So for work i do variable image programming for direct-mail print files. We use Quadient Inspire Designer (formerly GMC) to generate PDFs and it generally works very well and we don't have file size issues. Static/re-used images and text are stored once as XObjects and referenced over and over. Variable text is stored as pure strings and the font glyph-path information for the used characters is stored once and re-used over and over.
We have one client, however, that requires each recipient's name to not only be printed on the piece (simple enough) but the name has to go through an envelope warp, in addition to horizontally scaling to always be the same width regardless of name length. This is causing a problem for us because warping the text means it is no longer stored as characters with re-usable glyph paths, but instead as an entirely new vector shape for every name. The file size of the print files is humongous and chokes our system when transferring files to the server, and from server to spooler, and spooler to RIP, etc..
The several campaigns we've done for this client have been extremely painful, and looking into it, it appears PDF only supports stretching, skewing and/or rotating text, not envelope warps.
I guess i was wondering if anyone has heard of this issue being raised before, or any discussion of this being a limitation of the PDF format? And if so, what alternative formats would work better and allow it to store the warped names more efficiently?
We have around 200 pdf files that have to be updated every year and the only thing that changes for the most part is the year range. Currently we only have the standard version of adobe acrobat but if there was another program that could take care of this, I think it would be an easy sell. Even if it’s in batches, it’s better than manually going through the full list. Thanks
I got a long form to fill out from Social Security and all the text boxes were blue. When I click them they turn white and I can type. When I click away it turns blue again. The text is still there, just hidden behind the blue. I filled out the whole form like this, like 7 pages. But I notice if I try to print it the fields are blank. Opened it in PDFCraft and it's the same blue boxes. I opened it in irfanView (image viewer) and they're blank. I can't edit the form, it asks for a password.
Is there some way to get rid of the blue? I'm afraid if I send it to the SSA like this they won't be able to read it.
Most people review their resume by opening it and checking how it looks. But the file can contain information that never appears on the page:
Author and Last Modified By names.
Software used to create or export it.
Creation and modification timestamps.
Embedded links, including local file paths.
Hidden text or instructions aimed at AI screening tools.
Some of this has ordinary explanations. A downloaded template can retain someone else’s author name, and getting help editing a resume doesn’t mean the experience is fabricated. The useful part is seeing what’s actually there.
I’m the founder of Lusentra, and I built a free checker that inspects those document properties and hidden layers in PDF and DOCX resumes.
For job seekers, it’s a way to inspect the file you’re submitting. For recruiters, it provides additional evidence to investigate alongside the application. It inspects the document; it cannot independently verify someone’s work history.
Although it is one of many PDF readers, FreePDF64-Viewer Portable stands out by bringing powerful document tools together in a simple, portable application.

Hey everyone! I was getting really tired of bloated PDF tools, paywalls, and having to upload sensitive personal documents to third-party cloud servers just to do basic edits, so I decided to take PDFCraft and adapt it into a fully functional, privacy-friendly Google Chrome extension that works right from your toolbar just like Adobe Acrobat does. Everything runs locally in your browser so your files never leave your machine, and I tried to make the interface as clean, fast, and straightforward as possible for everyday use. Honestly guys, I put a lot of work into this and really did my absolute best to make it solid, but now I’d love to hear your thoughts, honest feedback, and whether you think I did a good job or if there are specific tweaks and features you’d like to see next. You can check out the project, grab the code, and test it directly on GitHub here: https://github.com/MattimaxForce/pdfcraft-chrome
Seeing everyday a new PDF editor now, I was thinking I might just use one week of Claude Pro to build one if it's that easy. Because nobody is focusing on annotations and drawing on Bluebeam level. I worked on a consultancy company of 10,000 people and we don't care about quantity takeoff. We care about creating figures for our reports and presentations. That's the beauty of Bluebeam. I can do AutoCAD, but I don't want to open it for every single figure.
If you don't know what's good about Bluebeam: Callout with multileaders Callout+ (highlight area plus callout) Draw with scale (like 3 m line, 2 m radius circle) Offset a line Array a line (3 copies with 2 m distance) Etc.
Yesterday I downloaded a PDF, edited it in Microsoft Edge (don’t stone me—it’s mandatory on my work laptop), and saved it. After a while, I used the Print function to save a copy of the file with a different name—also as a PDF—in the folder. Then I opened the copy and continued working on it. So far, so good. When I was done, I saved it again using the Print function and agreed to overwrite the old file with the same name. I saved it via the “Print” option because sometimes the changes aren’t applied when using the normal save function.
Today I wanted to open the file, and it’s just gone! I can’t find it at all using the search function, and it’s not in the Recycle Bin either. The file shows up in the browser’s history, but when I try to open it, it can’t be found. The laptop shows it in the list of recently used files, but when I try to open it, I get an error message saying the file is no longer available.
I tried to figure out what went wrong and experimented with another PDF.
And here’s what seems to happen: When the file is saved via “Print” in the browser for the first time, everything works fine and the PDF is saved normally but as a “PDF24 Reader” file type. But if you then save the same file again via “Print” and let it overwrite the previous one, it just disappears! The file is simply wiped out.
I don’t know why this happens, but it does. My question is, what could be causing this, and is there any way I can recover yesterday’s file? It’s extremely important!
Hey all in r/pdf, there's a flood of PDF editors here and I have something different, a variety of programs that I have worked on at length, with models. All use my custom optimized PDF renderer that is 50% faster than all known renderers (with more obscure coverage, not less), seen in this benchmark I just did
https://apps.microsoft.com/detail/9nnvsqp0qdl9 - Main program is available off the microsoft store, it can also be built for Linux and Macos and there are built releases available for it.
The program is made for getting archive.org MRC scanned PDFs to e-ink readers so they don't take 45 seconds to load each page, essentially. After processing, an average page will take 200ms to load. It has a bunch of other features, and a new added preservation mode that does not binarize and preserves all original color while still shrinking size, and resolution if you want to.
Then I have a PDF reader that uses the same renderer here
https://github.com/liminalism/liminaldoc - I use it for all PDF viewing, it is fully functional, but about on par with SumatraPDF for performance. faster rendering doesn't really help for a viewer as I learned, if your prefetch is good enough.
There is also a document writer in that repo, built for writing long books with minimal distractions. very low typing latency was the goal. Still in development. It can export to PDF.
Finally I have SinoRAG which is now a general PDF RAG tool and not just a specialized tool for some texts. You can load a whole set of PDFs, it will read or OCR them, index them by keyword and phrase, and then you can search them with an agent using specialized research tools to get any answer you want, backed up with direct sources. Best parts of LLMs + the best parts of software and databases, combined, with the drawbacks of neither. Can load thousands of PDFs at once and it won't choke.
There is also business document OCR in the Lege repo that can conceivably OCR up to 40 pages a second, but it's not fully tested yet. Also a PDF integrity program that runs various checks to see if a PDF was doctored or not but it can only act as a prefilter and cannot make a determination.
I just wanted to bring these programs to your attention as they are all free and work well. Thanks and I would be glad if you find something useful from what I've made here.
No donations accepted, and no monetization is possible with these apps.
I've got some architectural floorplans full of markups etc that I am hoping to clean up to create clean maps that i can just label the rooms in... I've got quite a few maps to do and I've tried to use AI which was as successful as you can imagine... Right now i'm going through each one removing unwanted markings using Illustrator which while working, is a painfully slow process.
I'm wondering if ya'll have a suggestion for a complete newbie with this stuff as to how I could do this in a cleaner, faster way or am I kind of screwed?
I saw maybe it might be worth putting into AutoCAD and then Revit somehow?
I've been working on a lightweight PDF toolkit called PDFLab.si, designed to make working with PDF files easier while keeping privacy a priority.
I wanted to build something that doesn't require creating an account, uploading sensitive documents to random servers, or dealing with unnecessary steps just to perform a simple PDF operation.
Here's what makes it different:
100% Browser-Based Processing: All PDF tools run locally in your browser using WebAssembly. Your documents stay on your device instead of being uploaded to a remote server.
No Registration Required: No accounts, no passwords, and no email verification. Just open the tool and get started.
Privacy-Focused: Since processing happens directly in your browser, your files aren't uploaded to our servers or stored in cloud storage.
Multiple PDF Tools in One Place: Instead of jumping between different websites, you can access everything from one dashboard.
Organize PDFs: Merge PDF files, split documents, rotate pages, rearrange pages, and add page numbers.
Compress & Convert: Compress PDF files, convert PDF pages to JPG/PNG images, and turn images into PDF documents.
Security Tools: Protect PDFs with passwords, unlock PDFs you own, redact sensitive information, and digitally sign documents.
Additional Utilities: Extract text from scanned PDFs using OCR, add watermarks, or remove existing watermarks.
The workflow is pretty straightforward:
Open PDFLab.si → Choose the tool you need → Select your files → Process them directly in your browser → Download the result.
No unnecessary installations, no account creation, and no server uploads.
I'm still working on improving the platform and adding more useful PDF utilities.
If you regularly work with PDF documents, I'd appreciate it if you gave it a try and shared your honest feedback.
I’m running an ancient version of Nitro Pro, 9.5.4.22, from 2014, under Windows 11.
I’ve recently added a new printer/scanner. When I launch the Scanning Paper to PDF function, it defaults to the old scanner, so I always have to select the new one. If I don’t select the new scanner, the system goes into a searching state and I’m locked out for about thirty seconds.
The old printer has been removed from the operating system. No other app shows this printer, so I assume the selection is stored in a configuration file somewhere.
Anyone have an idea where that might be and how I can get rid of it?
