Compress PDF
Shrink PDF file size without losing quality.
or drag and drop · max 50 MB
Upload a PDF and reduce its file size for email, web upload, or storage. The compression runs locally — your file is never sent to a server. Great for shrinking scanned documents, image-heavy reports, or oversized contracts so they fit under email size limits. Choose a quality level that balances file size against visual quality.

- It depends on the content. Image-heavy and scanned PDFs typically shrink 40–70%. Text-only PDFs that are already optimized may only drop a few percent.
