This may be outside your plan, but I really could use a pdf editor that makes Internet Archive book scans more readable.
Apparently, the scanner(s) adopt some compromise setting that renders halftones OK, but gives all text a "dishwater gray" background.
If there are few pictures, I run the PDF through a quartz filter in Preview to threshold the text and later merge graphics pages with the "contact sheet" view from an un-threshold-ed image in Preview.app. This is slow and tedious.
Of course, computers are "smart," so they tell me, and should be able to recognize a picture from a block of text on the same page and render each one appropriately.
I used to do such editing of really important documents (like ads for pioneer computer products and gizmos like GENIAC and such)[0] pretty much by hand, splitting a PDF, if needed, into multiple images and hand/batch editing, then merging again.
I could use ImageMagick ... but it's not adaptive, as described above.
I tried it. Looks great. Just few refinements from my side.
- Undo is not working. If you applied something it will be done. I had to reupload the pdf to again make the changes.
- I tried the text editing, it is having a defualt font family of `helvetica` and is automatically applied to the selected text once clicked and there is no way to undo or fix it.
Yes, it definitely is. It handles everything from the basics like editing, signing, and merging to more advanced stuff like OCR, redaction, and digital certificates all in a clean and lightweight interface.
The desktop app is only 58mb and uses effectively zero CPU, so it's about as far from bloatware as you can get.
Shoot me an email at joe@breezepdf.com — happy to jump on a call and walk you through it before you get it for your company.
Some features took a longggg time to do, such as table extraction, text editing, and (surprisingly) preserving positioning of elements (text, images etc.) when rotating the page in the downloaded file - PDF specification has a different orientation system than the web, so this was very intricate to get correct.
A lot of PDF editors have tools that all work independently, meaning you have to use each tool separately. My decision to add all the features I did while keeping it in one editor was because I felt that was a better user experience, but I means that all features become intertwined, which added a ton of complexity managing that.
Nice tool. I like the local approach. I think a nice feature would be to remove all PII from documents, so that users can redact PDFs and upload to their favourite LLM.
Great idea, though I haven't had a chance to use it much (yet). I especially appreciate the end-user control of the documents - that they never leave the user's computer. A question for any newish PDF application developer:
A valuable feature of PDFs is wide and long compability. What I output now should be fully readable and usable on any system and in 20 or maybe 50 years. [0]
How do you have confidence that what you implement meets that specification? For example, if I edit the text, how do you know BreezePDF isn't subtley corrupting it? If I compress or flatten it, how do you know that about the output?
In fairness, it's a question for any file-based application, but PDF has a special status in it's universal availability and functionality.
Thanks! Feel free to send feedback to joe@breezepdf.com if you get the chance to try it.
Regarding your concern, if a manipulation of the PDF doesn't meet the standard specification, it won't render properly in a PDF viewer as it is in the present day, let alone in 20 years. All PDF viewers/editors worth their salt adhere to the PDF spec. So as long as the PDF specification stays the same, anything that renders correctly now in a PDF viewer will render correctly in the future.
For something like compression, if the file reduces in size and the PDF renders the same (minus expected potential minor quality loss), then you have evidence right there that it worked successfully.
I built BreezePDF with PDF spec adhering libraries, so everything should be up to standards.

I don't want to hijack the thread but isn't BentoPDF open source and does all that and more for free? https://www.bentopdf.com

Free is still in this post. It's free to use, you can use the editor as much as you want with 40+ tools. Just a limit of 3 exports.

Sounds like a job for ScanTailor. I'm not aware of an actively developed alternative. The version on my system comes from ScanTailor Advanced [3].

Neat idea. Basically an "Enhance Readability" button. I'm looking into how it can be done, will report back.
Love it! Bookmarked for the next time I need to sign a PDF and then will pony up the $$.
Awesome! Would love to get your feedback once you try it.
anytime. Feel free to email me and remind - email in profile.

Thanks for trying it!
In what scenario was undo not working? If you can provide that context, I can dig into it more as to what wasn't undoing properly.
For text editing, I see the issue with that for some of the fonts. Fixing now
Sorry for the trouble!
Font change for text editing is fixed now
Note that this "free" PDF editor uses MuPDF under the hood which uses an AGPL license with the desktop version is being commercial.
Unless BreezePDF is open source, (it is not) it is in violation of MuPDFs AGPL license.

Is this a viable alternative to the Adobe PDF app on Windows? I'm looking for an alternative for our company to replace Adobe's bloatware.
Yes, it definitely is. It handles everything from the basics like editing, signing, and merging to more advanced stuff like OCR, redaction, and digital certificates all in a clean and lightweight interface.

Is it a one shot AI generated site?
Far from it haha

Good suggestion! I'll look into implementing that.
I made a first version of it if you want to check it out! It's under the "markup" tab
