- Click Compress PDF and download the result.
Why compress pdf?
Scanned documents and image-heavy PDFs balloon fast. Compressing re-renders pages at a smaller size so the file is far easier to send.
Does converting affect quality?
Pages are re-rendered as images at your chosen quality, so text becomes non-selectable and very fine detail can soften. Lower the quality slider for smaller files.
Frequently asked questions
Are my files uploaded to a server?
No. This converter runs entirely in your browser, so your files never leave your device.
How much smaller will it get?
Scanned and photo-heavy PDFs often shrink by 70–90%. Text-only PDFs shrink less.
Can I still select text afterwards?
No — compressed pages are images. Keep the original if you need selectable text.
