Common questions answered.

It depends on what is inside the PDF. Scanned or image-heavy files shrink the most, often by 50 to 90% with Maximum. Text-only PDFs have less room to shrink.

Light and Balanced compression run entirely in your browser, so 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, because compression targets embedded images and redundant data rather than text layers. Images are recompressed, so the highest 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.
