Key features
Three clear levels
Pick the balance between file size and visual quality.
Great for scans
Photo-heavy documents and scans shrink the most.
Local processing
Compression happens in your browser, not on a server.
Frequently asked questions
Will the text still be selectable?
No. This compressor rasterises pages, which is what makes scans much smaller. Use Light if you need maximum fidelity.
How much smaller will my file be?
Scans and image-heavy PDFs often drop by 50–80%. Text-only files shrink less.
Is there a size limit?
The limit is your device's memory. Very large files take longer to process.
Good to know
Most PDF bloat comes from full-resolution photos embedded in the page. Re-encoding those images at a sensible resolution is the single biggest win, and it is usually enough to slip under a 10 MB email limit.
