Compress a PDF
Shrink file size for email and uploads — see the before/after size the moment it's done.
Your file never leaves your device — everything runs in your browser.
How compression works on PDFlee
Shrink a PDF that's too big for an email attachment or an upload form. You see the before and after size immediately, and the compressed copy downloads as a new file.
Compression is a premium operation (2 credits, about €1) because heavy files take real work — but like every PDFlee tool it runs locally in your browser, so the file itself is never uploaded.
How much smaller will my PDF get?
It depends on the document: scans and image-heavy PDFs shrink the most, already-optimized text PDFs the least. You always see the exact before/after size before deciding to keep the result.
Why does compressing cost credits when other tools are free?
Compression is the heaviest operation we run and typically targets the largest files. It costs 2 credits (about €1) — still a fraction of a monthly subscription, and there's nothing recurring.
Is my file uploaded to be compressed?
No — compression also runs inside your browser. Even paid operations on PDFlee keep your file on your device.
