PDFsam (PDF Split and Merge) is well worth trying if you need to
You can try:
Free PDF Editor (supports *.fpe files)
Linux (you can always emulate it or use it from live CD such as Knoppix or using Docker):
Not editors, but have some functions to do some minor changes to PDF files:
Other solution could include:
AbiWord by importing PDF into editable word processing ...
I know two solutions for this:
1. Convert PDF to some other editable format and convert it back
2. Use LibreOffice Draw
If you could not find an PDF editor that you like, then, you can convert your documents to some other editable format, and later, convert it back.
For that, I would recommend you to use Pandoc
You can convert PDF (through ...
So far I have been using Xournal for this purpose and I am quite happy with it.
It essentially allows you to draw on top of the PDF using text and primitive drawing routines.
Regarding your criteria:
Linux – yes
GUI – yes
additions-only – yes
responsiveness – I haven’t had any challenging cases yet, but so far everything works fine.
gratis – yes
You definitely must try out PDFill Free PDF Tools
functions to merge, split, reorder, delete, encrypt, decrypt, rotate, crop and reformat PDF pages, to add information, header, footer and watermark, to convert images to PDF, PDF to images or PostScript to PDF, to delete, flatten and list form fields, to scan to pdf, to create transparent image, and more.
You may try to use LibreOffice to convert first the PDF into an ODT file that is of course editable.
If the PDF has not a very sophisticated format the conversion is pretty good.
Free, open source.
Warning: The fonts may look different from the original, and capitalization is often off.
Obviously, there are not that many open source options for PDF editing. However, you might try vector graphics editor Inkscape - free, open source and multi-platform (including GNU/Linux). However, AFAIK, it doesn't directly support editing existing multi-page PDF documents (seems that it works with single page). Having said that, if you're creating a PDF ...
Yes, at least three come to mind (partly copied from my own answer at https://softwarerecs.stackexchange.com/a/31158/22778):
That is the tool I use for larger PDFs and bulk operation. It's great for splitting, concatenating and rotating PDFs. I use krop (see below) for cropping.
Install with apt-...
The trick that you can use is to edit your text on your phone in "plain text" using one of the mark up languages that includes support for mathematical mark-up examples include ReStructuredText and markdown, there are cheat sheets galore on the net for both. Saving them to a location that you can access from your computer and using a tool to generate the ...
Okular supported annotations for some time, but since recently, you can also save the annotated PDF using the native PDF annotation format. You can mark specific text passages and add a comment to this; you can also place comments not anchored to a specific text and draw freehand or straight lines, polygons, and ellipses. I recently used this for annotating ...
I would suggest taking a look at Elsevier's Mendeley research paper sharing and management software, and its desktop client specifically. Note that it is a lot more than just a PDF annotation tool it is a research tool that covers a lot more areas.
It allows you to annotate PDF files with:
General Notes i.e. notes on the whole file
Sticky Notes i.e. notes ...
I did my homeworks and dig out an answer for myself. I write it down hoping someone else might find it useful. Yet any suggestions will be very welcome and appreciated.
After tried more of the available apps, I came out with 3 that caught my attention and deserve some words:
Xodo PDF reader/editor;
Foxit MobilePDF lite;
PDF Reader Classic (I think is the ...
For interactive pdf editing I would suggest installing LibreOffice which can edit most pdf files and write pdf files.
Note that pdf files from some sources, such as most scanners and some software, do not contain any text and instead contain either images of each page, the vectors to draw the text, or more than one of these - such files are never going to ...
NAPS2 is a free, open source Windows application (with experimental Linux support in beta), available in both installer and portable forms. I believe it does everything you want it to. While it was originally intended for scanning, you can import a PDF (drag and drop) and then add, remove, and reorder pages. You can then reexport as PDF. If you want to ...
Your image is from ancient times Acrobat Pro... Nowadays I think Free Acrobat Reader can do the same (although it is called comments, it is just like the typewriter.)
See here in action:
If you want something with a bit more options of formatting etc. You can take a look at Foxit Reader which has a Typewriter option:
If the school is using a form created by them to collect information, they are aware that the limitations of this form will result in un-formatted text. If the school staff is sufficiently qualified, the received forms can be auto-processed into a database, which would also strip off any formatting. This aspect of collecting this information also "levels the ...
If the handwriting is in a different colour to the rest of the text you could probably use ImageMagick to replace all occurrences of that colour, (within a specific margin of colours), with white. See https://www.imagemagick.org/discourse-server/viewtopic.php?t=18196 for some tips on getting started with this.
You can redact image pdf files using LibreOffice Draw:
Free, Gratis & Open Source
If you have to have a web interface there are a number of projects looking at running LibreOffice in a web browser - possibly your best bet would be to take a look at Open365 which should allow you to host your own online LibreOffice from a docker image.
Master PDF Editor can do that. A trial is available for Windows. Price is reasonable at $50 USD.
Well, it doesn't insert a PDF image directly, but it can copy an image from one PDF into another, including vectors.
I don't want to do these because the image quality will decrease.
Cropping a picture (wheter in a PDF or not) requires to encode it again. Usually pictures in a PDF use a lossy compression, so you can't do that without losing quality. But most of the time you can achieve that with an almost unnoticeable quality loss.
The good news is that there is no need ...
I think xodo is a good option in Windows. There are also a web app ande Mobile versiones.
It's easy to annotate, edit the pdf and add signatures. Also you can delete, insert and rotate pages. There are several annotation tools (comment notes, text highlights, text underlines, signatures, text, arrows, etc.) Works great with stylus.
OpenOffice/LibreOffice can export any document as a PDF file.
OO/LO can also create PDF forms, at least well enough to be able to programmatically fill them out using PHP and FDF..
The "signing" of a PDF file is an Adobe thing as far as I can tell. Of course, you could use gpg/pgp and sign documents with your public/private key pair...
If you are wanting to work with with a commercial OCR SDK you could check out the LEADTOOLS OCR SDK. You can easily OCR a document in just few lines of code, see below.
// Initialize the OCR engine
ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.Advantage,
// Startup the engine
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS 19\Bin\Common\...

I am not sure what you mean by "cut" in this context.
I use the free version of PDF-XChange Viewer (PDFX site )which has both installed and portable versions. It is free in a slightly limited version. The PRO features are clearly shown in the menu system labeled as PRO. The linked page indicates that it has been replaced by PDF-XChange Editor which ...
