I need to urgently send some very sensitive documents to an organization and I want to add a tiled text watermark to them, like the picture below: [how-to-add-a-tiled-watermark-to-photos] The problem is, I can’t seem to find any free privacy-friendly tools that allow me to do that easily. It’s of…

I have installed this app before haha, just didn’t really had the need for all the photo editing and didn’t realize that the app also had a watermark feature to it. Definitely a feature fest it is OMG. :joy: There is still quite some barrier to entry because it’s not universal like a website/isola…

[image] kissu: Especially with features tools like steganography (might be overkill/hardcore for my own roadmap :joy:). Steganography are invisible watermarks, right? I read about it yesterday, and it is my understanding that visible watermarks are safer because they are harder to compromise…

How did I not know Proton had this? I may be slipping. But thanks a lot for sharing!

Steganography are invisible watermarks, right? Hidden messages yes. I am not a crypto expert and not sure how to achieve this code-wise haha, but maybe when I’ll give it a look might look easier than expected. :rescue_worker_s_helmet: As for the tampering with it, it’s also what I read in some …

No. Slipping. As in, slipping to keep up with things.

I don’t like PDF24 (prefer pdfsam), but it’s allowed and used at my work, and they are really careful with software provided. Just don’t use web version, but desktop program, if it has what you need.

I actually recommended and use PDFSam for splitting and merging PDFs at work and another person for education use, all I can say is avoid the installer as I have no idea what happened, for some reason it replaced PDFSam basic with enhanced. Overall great software though for FOSS

I found a temporary solution. My sister who is visiting has Foxit PDF Editor installed on her computer, and it supports watermarking with tiled text. It was super easy. It’s not FOSS, but it worked. I will consider getting it for myself, but I really think a FOSS/Privacy company should create a fre…

Bentopdf is the open source alternative that works on the browser side, although alternatively you can also self-host stirlingPDF . Edit: Just in case, I don’t recommend the StirlingPDF web option since it works on the server side, but its interface may be better for some who can self-host it.

Are there any free privacy friendly tools to add tiled text watermarks to documents?

Some time ago, I looked for online options to replace PDF24. I haven’t tried the StirlingPDF desktop application, nor do I have the knowledge to self-host, so I ended up sticking with BentoPDF. Another alternative for self-hosting that I forgot to mention and that you could try is SignaturePDF, which is more focused on signing PDFs.
