Compress PDF Online
Lossless mode restructures the file and keeps text selectable. Balanced and Strong modes re-render pages as optimized images for much smaller files — ideal for scanned documents. If the result would be larger, Paperly keeps the original.
This tool runs entirely in your browser. Your files are never uploaded.

Frequently asked questions
How much smaller will my PDF be?
Scanned and image-heavy PDFs often shrink by 50–90% in Balanced or Strong mode. Text-only PDFs are usually already compact; use Lossless mode for those.
Will text stay selectable?
In Lossless mode, yes. Balanced and Strong modes convert pages to images, so run OCR PDF afterwards if you need searchable text.
Is my file uploaded?
No. Compression runs entirely in your browser.
