Frequently asked questions
Will compressing make my PDF blurry?
Light compression keeps exact text and vector content. Balanced and Maximum rasterize pages into images, which can soften photos and fine text at high zoom.
Why didn't my file get any smaller?
Some PDFs — already compressed, or mostly text — can't shrink further. The tool tells you and keeps the original rather than making it bigger.
Is there a file size limit?
No fixed limit, but very large PDFs take longer since compression runs in your browser rather than on a server.
