Compress PDF
Shrink scanned documents, catalogues and photo-heavy PDFs so they go through email, WhatsApp and portal uploads. Pick a quality, see the new size, download. The file never leaves your browser.
Questions people ask us
How does it compress?
Each page is re-rendered as an image at the quality you choose, so scans and photo-heavy catalogues shrink a lot. Text becomes non-selectable — use it for sharing, not for editing.
Is my file uploaded?
No. Everything runs in your browser using pdf.js and pdf-lib; the file never leaves your device.
Why is a text-only PDF not much smaller?
Text PDFs are already small; compression helps files with scans, photos or high-resolution images.
