About this project
Image, PDF and privacy tools that run in your browser, built so that anyone can use them.

The name
Pseudononymous is a crossing of pseudonymous and anonymous. That blend describes the project fairly well: the goal is not to disappear from the internet, which is close to impossible anyway, but to decide which version of you is exposed, and how much.
Why it exists
Plenty of sites offer to compress a photo, merge PDFs or strip metadata, and almost all of them ask you to upload your files to their server first. It is an odd bargain, especially when the file is your passport or your payslip. Here there is no server to upload anything to, and that is not a technical detail — it is the whole idea.
The other reason is simpler: almost every privacy tool is written for people who already know about privacy. This one is built so that your grandmother and your nine-year-old niece can both use it, in their own language, without signing up or configuring anything.
What is here now
- Eleven tools for images, PDFs and privacy, finished and usable.
- Practical guides that answer specific questions and lead to the tool that solves them.
- Everything runs in your browser. No accounts, no cookies, no third-party analytics.
- It installs as an app and, on Android, accepts photos and PDFs from the Share menu.
- Spanish and English from day one, each with its own URLs.
- Light and dark themes, both designed with the same care.
- Everything is checkable from your own browser, with nothing to take on trust.
What comes next
More tools that can run entirely on your device, such as converting HEIC photos or compressing PDFs, and more languages, starting with Portuguese, French and German. What will not arrive is anything that needs your files uploaded to a server: that is the reason the project exists, not a temporary limitation.
Later, a browser extension that cleans tracking from links as you copy them, and on-device detection of faces and text to suggest what to cover in a screenshot.
How to help
The most useful thing you can do is tell us when something does not work. A security report is the most welcome of all, and the security page explains how to send one. But if you spot a translation that reads oddly, an explanation that does not land, or a tool that misbehaves on a particular file, that counts for a lot too: real usability only shows up when real people use the thing.
