Sejda

Sejda can do a lot of things and still have a clean, intuitive interface, with virtually no learning curve. It has a desktop application, which makes all the difference to me, there is no need to use web apps. You can quickly manipulate PDFs, such as filling out forms sent in PDFs, inserting an illustration containing your physical signature of the document (not a digital signature, just an illustration representing your signature). I think of everything, what I like the most is the speed at which I can do all this with Sejda. It's not time consuming.

To be honest, I have no complaints about the tool. For my use it works perfectly. Of course, there are many things that the tool doesn't do, and for that it is necessary to use another tool. Especially reading and tagging PDFs, a constant demand in many management professions, cannot be done in Sejda.

The shear amount of features, silky-smooth desktop & web interface & the ridiculously-low subscription compelled me to stick with Sejda for my PDF-handling workload. Both the website & desktop versions equally offer tons of must-have features such as PDF conversion, size-reduction, merging & editing as well as page extraction, deletion & watermarking all of which I find myself using regularly.

While the OCR functionality is outstanding here, it can sometimes take its sweet time processing Arabic text (especially with content apparently using the bold, Sultan font). I hope to see an accelerated performance in future updates.

several tools available
some very unique tools like' breakdown by bookmarks'
available on the web as well as desktop
very nice appearance
pretty stable, rarely encounter errors, does its job
also has the ability to convert between various other document formats and PDF and converts them very fast
merging two files is quite advanced compared to other PDF editors. you can even alternate and mix two documents which come very very useful at times
several free to use features (3-tasks per day) which is more than enough for occasional users
updates so frequently with new features and fixes

flexible pricing options, including even weekly.

you first choose what you want to do and then choose the file. a pretty unusual and problematic approach
devoid of most file editing capabilities, so you can not use it to compose a PDF
subsciption is too costly. it will cost you as much as microsoft office 365 which seems way to much for a PDF tool

This program can do almost anything you'd need to do with PDF documents - converting to a text or image file, merging or splitting pages, compressing based on file size, editing the document, e-signing documents, and more. It's also free to use up to three times a day, and I can usually get my tasks done within those three uses. (The premium version is fairly priced, and much more affordable than Adobe Acrobat, but of course Acrobat is a much better, more powerful application.)

The program (both the desktop version and the online version) is divided by function (such as merging documents, converting, editing...). This can sometimes make it cumbersome and inefficient to accomplish many different kinds of tasks in one go. This is especially significant if you are using the free version, because you are limited to 3 tasks per day. However, it's still a useful tool that works relatively well, and can save you a lot of money if you only need a PDF editor every now and then.
