SumatraPDF is among the OSS PDF tools I use.
Since Adobe is pushing a more aggressive stance for monetization of Acrobat, I am trying to replace selected PDF workflows with OSS. Here are some of the tools I use.
qpdf
removing passwords, unlocking PDFs, conversion
install in WSL with apt-get install qpdf
remove password with qpdf --decrypt --password="" input.pdf output.pdf
PDF4QT - Open Source PDF Editing
Deleting, Sorting, Extracting Pages
Currently, no choco release available, must be installed manually from PDF4QT/releases
Inkscape, LibreOffice Draw
editing PDFs, adding text
Mupdf
Command line tool and Python package for parsing, filling forms, adding text
SumatraPDF
Viewing of PDFs
pdfplumber
Awesome python package to extract tables from PDFs into data pipelines. Use with Jupyter Lab
- dustingetz 3y agohow can i sign and date a PDF with a bitmap signature without 9999 janky clicks
- quyleanh 3y agoActually SumatraPDF is using MuPDF now. But there is some limitation on rendering PDF and eBook files. For example, formatting PDF file or displaying Unicode characters in epub file.
- sebras 3y agoDo you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ https://bugs.ghostscript.com/ if it also has the same issue? Thank you! There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)
- quyleanh 3y agoThank you for reaching out. Please refer to the following issue list from SumatraPDF repo [1] [2]. Epub rendering issue like [3] [4].

- dustypotato 3y agoFYI, you can use firefox for viewing,signing, and adding text to PDFs. You can also use it to remove password (just do print to PDF after unlocking it).
- beagle3 3y agoAt least as of Firefox 109, support for non Latin languages was broken to the point of being completely unusable.
- xattt 3y ago128 characters ought to be enough for everybody.
- GoblinSlayer 3y agoYep, it's codepage 1276 https://en.wikipedia.org/wiki/Adobe_StandardEncoding https://en.wikipedia.org/wiki/Adobe_StandardEncoding
- rstuart4133 3y ago> you can use firefox for viewing,signing I got all excited - then realised "signing" just means inserting a picture. Notably absent are open source tools for digitally signing and verifying PDF's. Apparently pdftk does it in a paid version. It's funny in a way - in this thread we have people wanting ways to modify a PDF. Yet to me, being any to prove it's not modified (eg, it's statement provably issued by some bank saying they transferred funds to my bank on behalf of person XYZ) is far more important. Instead we have companies offering paid "document signing services" which are built on sand - you can easily forge / modify any signed document they issue.
- ajyotirmay 3y agoOkular. Okular offers digital pdf signing
- Steve44 3y agoFor extracting to tables I've been using http://tabula.technology/ http://tabula.technology/ for a couple of years. It seems to do a pretty good job even with some fairly complex tables and I've not had any problems with it.
- Helmut10001 3y agoYes, tabula is the other table extraction tool. I used both and prefer pdfplumber because it is really robust and works well with Jupyter Lab.
- silicon_laser 3y agoyou can also use okular for visually select a table from a pdf and paste it in sone excel kinda software and okulars table select tool is not too bad
- mkl 3y agoPDFTK and pdfjam are two other useful command line tools. I use PDFTK for merging PDFs, extracting/deleting/duplicating pages, and decompressing so I can extract and manipulate text/data in raw PDF commands. I use pdfjam for n-up and adjusting page size and margins.
- djbusby 3y agoPDFTK can choke on some merges, some newish pdf features. In those cases one can use Ghostscript to merge and other manipulation.
- tjrgergw 3y agoI use xournal to add signatures (just pngs) and text to pdfs.
- acqq 3y agoI like k2pdfopt for reformatting pdfs for my e-reader. I've also used poppler's pdfimages but I'd prefer like something less buggy for my use case; any version I've tried had problem with one pdf made by Adobe InDesign. Also, tesseract allows creation of a pdf from the images with the embedded OCR text. It is also built in in the k2pdfopt.
- qwerty456127 3y agoAlso take a look at Okular. It's the only PDF reader I've seen to let you select a specific column in a table.
- deepspace 3y agoOkular is my go-to document reader across operating systems. In addition to PDF, it can open EPub, DjVU, JPEG, PNG, GIF, Tiff, WebP, CBR, CBZ, DVI, XPS, ODT and other formats.
- PhilippGille 3y agoYou mention qpdf not available in Chocolatey, but it's available in Scoop, which is another Windows package manager: https://github.com/ScoopInstaller/Main/blob/master/bucket/qpdf.json https://github.com/ScoopInstaller/Main/blob/master/bucket/qp...
- SushiHippie 3y agoFor other distributions / OS / package managers see here: https://repology.org/project/qpdf/versions https://repology.org/project/qpdf/versions

- ed_balls 3y agoMETA: What's the best way to convert pdfs to CSV/excel? Any new LLM tool?
- emeril 3y agoabbyy finereader 8.0(!!!) good luck finding it
- justsomehnguy 3y agoIt's funny what you are downvoted, but FR8 was way better OCRing Office-printer-scanned documents even against the much later versions of FR, I saw the comparison on the same source documents. > good luck finding it It's still available on the trackers.
- enthdegree 3y agoThis is a really obscure recommendation. Can anyone who knows about the specifics expound?
- Helmut10001 3y agoI think the best way to convert pdfs to tabular data is using pdfplumber together with a pandas (dataframes) workflow and writing results to CSV.
- MilStdJunkie 3y agoTabula
- xinayder 3y agoYou can also use Okular to open and edit PDFs, it's the document viewer from KDE.
- nolok 3y agoMay I recommend NAPS2 ? https://www.naps2.com/ https://www.naps2.com/ It's like PDF4QT but works and feel better to me.
- magical_spell 3y agoPdf-tools in Emacs is also great.
- ParetoOptimal 3y agoAnd it has a killer feature: pdf-view-themed-minor-mode It matches the pdf style/colors to your emacs theme! Sort of like a dark reader for pdfs, but it automatically adjusts to any theme based on some good but likely imperfect heuristics.

- georges_gomes 3y agoTo edit PDFs in Figma, it exists pdf.to.design now. https://pdf.to.design https://pdf.to.design
- nirav72 3y agoAdobe Acrobat reader installer is also almost a 1 gb download these days. One thing I do find that Acrobat does better is compression. I can usually reduce a PDF down to about 30%-40% of its original size without much loss in quality. I've tried other tools and they haven't worked nearly as well.
