About this tool
Reduce PDF file size with control over quality.
All processing happens in your browser. Your PDF never uploads to our servers. No account required, no usage limits.
Frequently asked questions
Is this PDF compressor free?
Yes, completely free with no usage limits.
How much will the file be reduced?
Typical reduction is 5-30% for text-heavy PDFs. For PDFs with many images, larger compression (40-70%) is coming via image downscaling in Phase 2.
Will compression affect quality?
No. We use object streams optimization and metadata cleanup — your content stays intact.
Will my PDF be uploaded to a server?
No. Compression runs entirely in your browser.
Does it work offline?
Yes, after the first visit.
