FAQ
Why is my PDF not getting smaller?
Text-only PDFs are already small. Compression works best on scans and documents with photos.
Will the text stay selectable?
No, pages are saved as images. Keep the original if you need to copy text.
Is it safe? Are my files uploaded?
No. The conversion runs entirely in your browser using WebAssembly. Your files are never sent to a server, so they stay private — you can even use the site offline after it has loaded.
