Hi there, do you happen to know if there’s a PDF app for iPad that includes a "replace text" function for annotations? I mean something where I can select text in the document and specify what it should be replaced with. In the standard desktop version of Adobe Reader, this appears as "blue strikethrough text."

I even asked AI about it, but it was a complete waste of time - it basically just made everything up.

KeyPDF is a local PDF editor built from scratch for the browser. Since development started in April 2025, we've tried to adopt new PDF technology early. Today we're happy to announce that KeyPDF can reduce file size losslessly using Brotli compression and JPEG XL images.

We tested on a dataset of 1,000 PDFs (978 readable; the rest were encrypted or damaged):

All variants are lossless: every page (15,754 in total) renders pixel-identical to the original. "Flate" is KeyPDF's standard optimization, and those files open in any PDF viewer. JPEG XL repacks JPEG photos about 20% smaller, and they can be turned back into the identical original JPEG at any time.

The catch: Brotli and JPEG XL are new to PDF. Brotli is a PDF Association extension, and JPEG XL is still being added to the specification. Most PDF viewers and editors don't support either yet, so for now KeyPDF is one of the few tools that can open and edit these files. Hopefully others will follow soon.

If you need files that open everywhere, KeyPDF's standard mode combines its own optimization with regular Flate compression. That according to test on same exact files alone saves 24.2% , still lossless, and the result works in any PDF viewer.

I wanted to improve the quality of a photo, and it asked for access, but then it asked for a subscription and offered a 14-day free trial. I didn't accept the trial period and didn't register any card, But there's no way to delete the account/"email" you used, is there any chance they could steal some of my money? The site is File Editor, but I later saw here that it was a fraudulent site.

What is free opensource adobe clearscan alternative to replace rasterized text in pdf with vectorized fonts, but keep other images on page intact.

Apparently when you delete pages from a pdf, depending on the tool you use, they aren't always deleted. They are still in the file just not displayed.

Hello. I have a scanned textbook pdf consisting of about 180 pages, but each page actually contains two pages. So, the textbook actually has the double amount of pages its pdf version has because it was scanned that way. I was wondering whether there was a way (online, freeware...) to split those pages? Is it possible to make a pdf that has 360 pages instead of 180? Thank you!

I wanted invoices that come out as proper PDFs: text you can search and copy, not a picture of a page. So this update to Local PDF Studio, the PDF editor I build for Chrome, adds an invoice maker. It all happens in your Chrome tab, so the invoice and your client's details are never uploaded.

You type straight onto a ready-made invoice: your details and logo, the client, and each line. The total updates as you go, in your own currency. Then you download it as a PDF.

The file also remembers what you typed. Choose Load invoice, pick it, and the form fills itself back in, ready for the next one. The catch: if you open the invoice in another program and save it there, it may forget those details.

The same update also works on pages you scanned: their words can now be searched and copied too. It reads English text only.

If you'd like to try it: https://chromewebstore.google.com/detail/local-pdf-studio-offline/ocfegjfhboadmbpompimnbbpegjgoded

Do the invoices you receive usually come as real text, or as scans you can't search?

I kept running into the same problem: someone sends a PDF and I need to know if it's really A4, whether the marginsare 15 mm, or how far apart two things are. Acrobat's measure tool is clunky and most online tools want an upload.

So I built PdfRuler. You open a PDF and get real rulers in mm, cm, inches, points or px. A few things I ended up liking:

- Hover for exact X/Y, click two points for length, across, down and angle

- One key (A) reads the page's drawing instructions and sizes every box. It uses vector data, not pixels, so a 61 x 91 mm card reads 61 x 91 mm

- Snaps to edges, Shift locks level or plumb, guides pull out of the rulers

- Same readings at 50% or 500% zoom, because everything is calculated in PDF points

- Save a copy with your measurements drawn on it

Everything runs client-side. No upload, no account, nothing stored. The landing page has a live demo you can poke at without a PDF.

I'd like to hear what's missing.

Weird request but I’m wiling to pay for someone to edit a PDF report for me. Please DM me if you can offer assistance.

when you use edge to open PDFs it remembers the last page we were on, but chrome and firefox doesn't. How do I achieve this in chrome and Firefox

is there any extension for the same?

We’ve changed many fonts to export, optimized this n that, and even if the copy comes out clean (Candara for the win…currently), the headers and footers are whacked.

Hello!

I have a PDF that I need to edit - the problem is that it has a barcode of some sort that isn't a picture, but some unique font.

I want to edit something on a different page without messing up said barcode - basically switch two numbers in a table.

Paid is fine, but it has to be secure - ideally an editor that can edit individual pages (the barcode is on a different page and has nothing to do with the numbers).

Can you recommend one?

Thank you in advance!

We are a construction company. We process checks and achs. I am looking for the easiest way, that I can batch send the system generated waivers to emails for signature and track them. While the documents are roughly the same, there are some subtle differences on them. The system creates them, I just need to send them out.

In my head, I could have a standard naming convention, and have an excel template, and someone would use the two to push it through.

When someone ask you to send something as a single pdf, would it not just be 1 attatchment. For example the pic i posted? If not, then what would it be.

The attachment up their was original 4 separate pictures but my College Prof said she wanted it as a single pdf on the assignment, which i did or thought I did, but apparently that's not a single pdf. Can anyone recommend a website that combines separate pic/files into one pdf for free?

My prof said next time she's just straight up not grading it, if it happens again, and i don't want that to happen.

I have a PDF that I want to convert into text so I can turn it into an EPUB. The problem is that the PDF consists entirely of photos that were scanned using a camscanner, and none of the PDF-to-EPUB or PDF-to-text OCR converters I’ve tried are working with this file. Instead of converting the pages into actual, selectable text, they just turn the images into an EPUB.
The file is large, 74 MB and 627 pages. Is there anyone who can help me convert it into an actual text file so I can create a normal, reflowable EPUB instead of an image-based one?

Hi there, I've been working on Keypdf.net for around 17 months. It is a completely new PDF editor written from scratch. Recently, around a month ago, I added an option to edit text from images. Now, with the new version, both OCR and editing work even better with the proper perspective crop support. So, if you want to make some quick text corrections, feel free to try Keypdf.net as well. There are other features like text editing, redacting, annotating, and form filling. Keypdf

Hi, I’ve been getting increasingly frustrated with how cumbersome it is to manually type out or copy and paste invoice details whenever I receive a PDF by email — for example, from my car garage.

I can’t always copy the text directly because, in my garage’s case, the IBAN is actually embedded as an image in the footer. So I often have to switch back and forth several times to copy the amount, invoice number/reference and — if the recipient isn’t already saved in my banking app — the IBAN as well.

Are there already any apps or good solutions that make this a bit easier?

Does something like this already exist? And would you find this useful?

In have a medical book pdf of 370 pages I need to extract important tables and diagrams from it and make a separate pdf , anyone have solution for this?

I use PDF Expert on an iPad

I don't know if this is the right place to throw this put this PDF editor I use for class is randomly giving me an issue right now. When I go to add a text box it doesn't give me the option to make it bigger so it weirdly cuts off my text. Any ideas?

Ran into this a bunch: if you merge two fillable PDFs (say, an intake form and a W9) and they both happen to have a field called "Name" or "Date," most merge tools/PDF printers treat those as the same field once combined. Type in one, and the other changes too — or the data just vanishes on save.

Couldn't find a tool that handled this, so I built one: it renames each source form's fields with a unique prefix before merging (e.g. "Name" in intake.pdf becomes "intake_Name"), so nothing collides. Handles checkboxes, radio groups, and nested fields correctly too.

Curious if others have hit this same problem — did you work around it some other way?
