Files never leave your device.

Note: pages are converted to images, so text in the output is no longer selectable. Best for scans and photo-heavy files.

How to use the Compress PDF

Pick a level and press Compress PDF. Each page is rendered and saved as an optimized JPEG, which is very effective for scanned documents and phone photos turned into PDFs. If the result would be larger than your original, the tool tells you instead of downloading.

Frequently asked questions

Why is the text no longer selectable?

This method flattens pages into images, which is what makes scanned PDFs dramatically smaller. Keep the original if you need searchable text.

Which level should I pick?

Recommended works for most email and portal limits. Use Strong if the file is still too large.

Is it safe for confidential files?

Yes. Compression happens on your device; nothing is uploaded.
