Compress PDF files online

Reduce image-heavy PDFs for sharing by choosing an export quality preset.

Select PDF files or drag and drop them here PDF only · up to 50 MB each

3 free exports per day · No signup needed

File and export limits

PDF input: 50 MB per file, 100 files and 500 MB per workspace. Split export supports up to 200 parts.

JPG to PDF also takes JPG and PNG images: 20 MB per image, and up to 50 megapixels for a JPG or 25 for a PNG. Each image becomes one page and counts as one file toward the workspace limits. No text recognition is applied.

Each device gets 3 successful standard exports per UTC day, shared by anonymous and signed-in free users. The allowance resets at 00:00 UTC (UTC midnight). Signing in, signing out or switching free accounts does not change it. No signup is needed to return tomorrow. A combined export counts once; failures and repeat downloads do not use another allowance. AI and OCR are not included in the free allowance.

How it works

Upload a PDF
Open Export and choose a quality preset
Download and check the result

Inspect small print and diagrams after export. File-size reduction depends on the document, not a promised percentage.

Example result

A two-page report with tables rewritten at a smaller size. Other PDFs may stay the same size or grow; compare your result.

Example details & evidence

Real editor export: 2 pages; 4562 input bytes, 3404 output bytes. Results vary by document: some PDFs shrink and others grow. Compare the actual result.

Examples use synthetic files, not customer documents. Generation notes and SHA-256 hashes.

Your files

Files are processed on the server, not on your device. Access is checked against your account or browser session. Save your own copy of the result, then use Documents to delete the job. Premium 1, 7 or 30-day retention choices do not apply to free editor files. Read about file handling.

Common questions

Will every PDF become smaller?

No. A document that is already optimized may stay similar in size or grow.

Which preset should I choose?

Start with Balanced. Smallest file can blur images; High quality preserves more image detail.

Does compression remove pages?

The quality preset does not choose pages. Check your page selection separately before export.

Can I undo the compression?

Lossy image compression cannot restore removed detail. Keep your original copy.
