How to compress a PDF online
1. Upload your PDF
Drag and drop the file you want to shrink. Files up to 1MB are supported on the free plan.
2. We compress it
Images and fonts are re-encoded to cut the file size while keeping the document clear and readable.
3. Download the smaller PDF
Save the compressed file and see how much smaller it got. No watermark and no account needed.
Make a heavy PDF small enough to send
Email attachment limits, upload forms, and slow connections all get in the way when a PDF is too large. Scanned documents and image-heavy reports are the usual culprits.
Compressing the file brings the size down so it sends and uploads without trouble, while the text stays sharp and the pages stay readable.
Smaller file, readable result
Compression re-encodes the images and fonts inside the PDF rather than just zipping the file, so the savings are real. If a document is already optimized, you get the original back instead of a larger copy.
Free to compress, nothing to install
Shrinking a PDF shouldn't cost money or mean installing Acrobat. Your file is uploaded over a secure (HTTPS) connection, compressed on our servers, and returned for download with no watermark. It is used only for the compression you requested and is not kept afterwards.
