PDF Compress
Shrink heavy PDFs to email-friendly sizes. Best on scanned or image-heavy documents.
🔒 Runs in your browser — your PDF is never uploadedPages are re-rendered as optimized images, which is what makes scans shrink dramatically — text in the output is no longer selectable, so keep your original for editing. If the result isn’t smaller than the original, we’ll tell you instead of giving you a bigger file.
Frequently asked questions
Is my PDF uploaded to a server?
No. Compression runs entirely inside your browser. Your document never leaves your device and is never stored.
How does the compression work?
Each page is re-rendered as an optimized JPEG image at the quality level you choose, then rebuilt into a new PDF. This dramatically shrinks scanned and image-heavy PDFs. Because pages become images, text is no longer selectable in the output — keep your original for editing.
Is there a file size limit?
No hard limit — processing happens on your own device, so it depends only on your computer's memory. Very large PDFs simply take a little longer.
