Compress PDF without uploading
The file is shrunk by code running in this browser tab, so you compress PDF locally — it never travels to a server, which matters for scans of IDs, statements and contracts.
Keeps working with no connection
Because you compress PDF client-side, on your own device, the tool keeps working after this page has loaded — even if your internet drops.
How it works
- 1Drop in the PDF you want to shrink.
- 2Pick a compression level — light, medium, or strong.

Questions people ask
Can I compress PDF safely if it's confidential?
Yes. Nothing is uploaded, so a confidential document never reaches anyone else's server. You can check this yourself in your browser's Network tab while compressing.
How does compression actually work here?
Each page is re-rendered as an image at a lower resolution and quality, then rebuilt into a PDF. That's why it works best on scanned pages or image-heavy PDFs — text-only PDFs are already compact and may not shrink much further.
Will the text still be selectable afterward?
No — because pages are converted to images, the output PDF is no longer searchable or selectable. If you need to keep selectable text, try a lighter compression level or skip compression.
Is there a file size limit?
No server-side limit. Very large files just take longer since everything runs on your device.
