FAQ

Common questions answered.

It depends on the PDF's contents. Scanned or image-heavy PDFs shrink the most — often 50-90% smaller with Maximum. Text-only PDFs have less room to shrink.
Light and Balanced compression run entirely in your browser — your file never leaves your device. Maximum compression uploads to our server for deeper processing.
Light keeps quality nearly untouched with modest savings. Balanced trades a bit more quality for noticeably smaller files. Maximum uses our backend for the strongest compression available.
Text stays sharp — compression targets embedded images and redundant data, not text layers. Images are recompressed, so very high compression levels can soften image quality slightly.
You get 30 free compressions per day. Large files work best with a stable connection when using Maximum compression, since those are processed on our server.
