- People compressing private documents or images
- Worth noticing
- The tool reports that files stay in browser memory, with no server upload or imposed size limit.
Field notes
The interface includes automatic, high-quality, balanced, and maximum modes, then reports whether compression actually reduced the file. Its implementation description names Canvas for images and WebAssembly for PDFs, with browser memory as the practical constraint rather than a service-imposed quota. The page also identifies the project as a one-person effort from Colombia and shows a monthly support target, including local payment options such as Bre-B and Nequi.
