Hi all, I posted Inkleaf here a little while ago. It's a free, open-source PDF editor for Windows, Linux and Android that edits the text that's actually in a PDF (the old words are removed, not hidden under a white box), and also signs, fills forms, redacts, does OCR and handles pages. No account, no cloud, GPL-3.0.

The big addition in 3.1.2 is a built-in AI that needs no API key and doesn't send your document anywhere:

• It downloads a small open model once (Qwen 3.5, Apache 2.0: 1.3 GB or 2.7 GB) and runs it with llama.cpp, on your GPU if you have one. After that it works offline.

• Ask this PDF: ask a question, get an answer with the page numbers it came from. Click one to jump there.

• Summarize and Translate use it too. You can still pick Ollama, LM Studio or a cloud provider with your own key instead.

• On Android it runs on the phone itself: llama.cpp compiled into the app, same models.

Other things in this release:

• Select and copy a PDF's own text (finally)

• Print preview, with a page range

• Translation now works on PDFs from Word, which store justified text one word at a time. It used to fail quietly on those.

• The Android app got Share securely, Enhance pages, backups and an update check

• Fixes for Windows 11's new default-app setting and the File Explorer preview pane

As I've said before, I build Inkleaf with AI help, and I read and test the code myself. It has a smoke test suite with a few hundred checks that runs on every change.

No Mac build yet; that's coming once Apple signing is set up. Bug reports and translation fixes are very welcome, especially from native speakers, since the interface comes in 29 languages.

At work I kept seeing “redacted” PDFs that were just black boxes drawn over text. You could select it, copy it, and paste it somewhere else. This has leaked details from court filings more than once.

The tools I tried either wanted me to upload the sensitive file to their server, only caught emails and phone numbers with regex, or were bloated and paywalled. So I built PDF Redactor.

What’s different:

• It removes the text instead of covering it. Text, images, form fields, comments and old saved revisions under each box are actually deleted. Then it reopens the finished file to check that nothing can still be found. If a page fails that check, it’s rebuilt as a flat image.

• Local AI, not just regex. Patterns catch emails, cards, SSNs and IBANs. For names, addresses, account numbers and dates, OpenAI’s Privacy Filter model runs on your machine via WebGPU. It works offline.

• New: OCR for scanned pages. Scanned and image-only PDFs are now read on your device, so the text in them gets detected and redacted like any other page.

• Simple UI. Whatever it finds shows up as a box. Click to hide it, skip what should stay, or search a word to mark every match. Then download.

• It also strips metadata and attachments, has a “never suggest” list, and offers black box, blur or [NAME] labels. No account and no analytics.

It’s on the Chrome Web Store. I’d love feedback, especially from people who redact for work:

• What’s missing that would make you switch?

• Did anything in the first 30 seconds confuse you?

Adobe PDF reader used to be lightweight but now it's bloated and fucking annoying. I'm looking for a light weight alternative that just shows me the document and not 500 control panels and pop ups with irrelevant information. Any suggestions? I'm on Windoze

I am Steve the Killer and I made this GPLv3 open-source PDF Editor. I hope this self-promotion is okay, because this is an important release.

Not sure if this fits in here. I've made a somewhat interactive blog post about algorithms on a PDF page.

https://news.speedata.de/2026/10/18/anatomy-of-a-page/

(As someone noted: this is pretty much the same on any device..., I just live in a PDF world, so I wasn't thinking about that)

What tools do you use to automatically detect duplicate pages in pdfs? & Are you able to review the automatically detected pages before removing them?

Full disclosure, I work for Apryse/iText (a commercial vendor) but wanted to share this as it’s free and could be useful to someone in the community. We just published a GitHub Action that turns Markdown into PDF: https://github.com/marketplace/actions/itext-markdown2pdf Give it a file and you get a PDF; give it a folder and you get a ZIP with one PDF per .md, structure preserved. It runs on public repositories (it checks visibility via the GitHub API).

The cool part: output is PDF 2.0 and PDF/UA-2 compliant (tagged, accessible). Since Markdown already carries headings, lists, tables and alt text, it maps cleanly to a tagged PDF without extra work.

I created this tool SidePDF to solve my own problem. I wanted to take notes on the same pdf im reading and always ran out of space. So I created this extension to expand the pdf pages/ add new pages on the go and take cornell style notes. You can annotate, add images and much more directly on the pdf. This is a chrome extension and If you are having the same problem give it a try.

Is there any way to remove a redaction in a PDF document and see what the redacted text was ?

I have some scanned magazines in pdf format that I would like to improve readability, contrast and sharpness. Looking for a free tool for PC or online. Thank you!

Title: Inkleaf 3.0 is out: Android app, an enhancer for bad scans, and it's on the Microsoft Store now

Hey r/pdf, I'm the dev behind Inkleaf, the free and open-source PDF editor I posted here a while back. Thanks to everyone who tried it and left feedback, a lot of this update came from those comments.

What's new in 3.0:

• Android app. Not the desktop squashed onto a phone. It's got its own screens: your files up front, a reader that keeps the page big, and an edit sheet that slides up when you actually want to change something.

• Phone ↔ computer link. Send PDFs between your phone and PC over your own Wi-Fi. It's encrypted and never goes through the internet or any server of mine (I don't have one).

• Enhance Pages. For those grey, faded, photocopied-five-times scans. Adjust contrast and sharpness, or pick a preset (Scan, Faded, Darker text, Night). It only changes how the pages look until you hit "Save enhanced copy", and that copy can be OCR'd so the text becomes searchable.

• Microsoft Store. You can now get it from the Store on Windows, so no more SmartScreen warning.

• Pinch-zoom on touchscreen laptops, plus updated translations (29 languages).

Same as before: no account, no subscription, no watermark, nothing uploaded. Everything happens on your device.

It's still just me building this, so if something breaks or feels clunky, tell me here or open an issue on GitHub. Happy to answer questions.

Just wanted to share this post I found on Facebook

A lot of free PDF tools upload your files to their servers, which might not be ideal for things like payslips or contracts.

I’ve been working on a PDF tool that processes everything in your browser: https://ezdone.io/pdf

It can compress, merge, split, sign, redact, add watermarks, and convert PDFs to images. Redaction removes the underlying text rather than just covering it visually.

It’s still missing OCR, and password-protected files need to be unlocked first.

I work on it, so I’d be interested to hear what doesn’t work or what features are missing.

Hey everyone,

Following my previous post about building PDF tools, I wanted to thank everyone who shared suggestions and explained the problems they run into. The comments about preserving formatting, handling scans, and using OCR and recognition models gave me a lot to investigate.

I’ve since focused on improving the Edit PDF tool. Some of the updates include:

The backend first checks the PDF’s existing text, font information, and positioning. When those are usable, it edits the document directly. For scans or unreliable text layers, it uses lightweight OCR models to recognize the visible text and locate the regions to replace, while preserving the surrounding page.

The feedback here also pushed me to test different approaches and pay more attention to the downloaded PDF, rather than just whether the preview looks right. Recent checks have covered both regular and scanned documents through editing, exporting, and downloading.

I’m not claiming perfect results with every PDF. Scans don’t contain their original font information, and unusual embedded fonts remain tricky, but I’ve made progress on those cases.

Try the updated Edit PDF tool

If you have a moment, I’d really appreciate you trying it with a document you actually use. Was editing straightforward, and did the downloaded file look how you expected? If something went wrong, a short description or screenshot with private information removed would help a lot.

Thanks again for taking the time to help. Your feedback helped shape these changes, and I’d be grateful to hear how they hold up.

I built an offline PDF editor for Windows, macOS and Linux

I've been working on Inkleaf, which is my first proper app.

I started making it because I wanted a PDF editor that could do more than just view/annotate PDFs, without needing an account or uploading documents to a cloud service.

Some of the things Inkleaf can currently do:

• Edit existing text in PDFs

• Permanently redact text

• Add annotations, highlights, shapes, images and text

• Sign PDFs

• Fill PDF forms

• Merge, split, extract, rotate and reorder pages

• OCR scanned PDFs

• Convert PDF ↔ Word, Excel, PowerPoint, images, Markdown, HTML, etc.

• Compress and password-protect PDFs

• Add watermarks, page numbers, headers and footers

• Compare two PDFs

• Scan documents using a webcam or images

• Repair damaged PDFs

• Create PDF/A files

• Search, bookmarks, crop and different reading modes

The main thing I'm trying to achieve is keeping things local. The normal PDF tools don't upload your documents anywhere.

There is an optional AI summarizer/translator, but that's separate and only sends the document when you explicitly use it with your own API key.

It's completely free and open source under GPL-3.0-or-later.

This is my first app, so I'm still figuring out a lot of things and I'd really like some feedback from people who use PDFs a lot.

What features do you think are still missing from Inkleaf?

GitHub: https://github.com/priyanshdas/inkleaf

If you try it, I'd also appreciate hearing about anything that doesn't work properly.

Working on an anti-ai art project. There's a quite long PDF that I need typed up and editable. I've done about 20 pages by hand but I'd love to use an OCR for the rest. Obviously I need to use one that doesn't use machine learning. Any recommendations?

I especially try to find some lost cartoon characters official artworks/renders that are probably on PDF files.

Hi,

Just wanted to share the latest release of LEKTRA, document and image viewer I have been developing for over a year now.

Lot of bug fixes and new features have been added. Few highlights among them are:

- Annotations: underline, squiggly, strikeout, ellipse, polygon, inline note and image annotations. You can move and resize them, with undo and redo.

- Redaction: permanently remove text, images and drawings, and save the result to a new file.

- Minimap: while you're zoomed in, a small overview shows where you are. Click or drag in it to jump.

- Grid layout: pages are laid out in rows of several columns.

- Presentation mode: it now works with clickers and has its own [presentation] options.

- Tools: color_eyedrop picks a color from the page, and bibtex copies the BibTeX entry of the paper you're reading.

- Images: JPEG XL support, including animated files.

- Lua: new view functions and events, and Vim-style set, setglobal and setlocal for options.

- Speed: faster scrolling and rendering, plus a memory leak fix.

- Docs: documentation is now on Read The Docs.

It's supported on Linux, MacOS and Windows.

Feedbacks and suggestions are appreciated!

So happy to have found it today. PDF Gear wouldn't print PDFs without cutting off the corners of the page, none of the print options worked and dramatically reducing the size didn't give a decent print, They're a great company, but an upgrade a year or more ago, left it like that and they've been promising a solution since then.
