Compress PDF
Shrink your PDF's file size. Everything happens in your browser — files are never uploaded anywhere.
Handy for getting a PDF under an email attachment limit or a form upload cap. The tool re-encodes embedded images to cut file size while keeping the document readable — no account, no watermark, no server round-trip.

Frequently asked questions
How much smaller will my PDF get?
It depends on the content — PDFs with large embedded images typically shrink the most, while text-only PDFs are already small and compress less.
Does compressing reduce quality?
Compression mainly re-encodes embedded images at a lower quality/resolution. Text and vector content stay sharp; heavily compressed images may look slightly softer.
Is my PDF uploaded to compress it?
No. Compression runs locally in your browser — the file never leaves your device.
