Compress PDF
Shrink scanned or image-heavy PDFs.
🔒 Processed on your device — nothing is uploaded.
Best for scanned and image-heavy PDFs. Pages are re-rendered as optimised images, so text in the result is no longer selectable.
About the Compress PDF
Scanned documents and PDFs full of photos can be several megabytes, too large for email and many online forms. The compressor re-renders each page as an optimised image, often cutting the size by more than half while keeping text readable.
When to use it
- Getting a scanned form under a 1 MB or 2 MB upload limit
- Emailing a photo-heavy brochure or portfolio
- Saving storage when archiving scans
- Making documents faster to open on phones
Tips for the best results
- “Recommended” keeps text sharp; “Strong” is for when size matters most
- Greyscale makes scans of black-and-white documents much smaller
- Because pages become images, text is no longer selectable — keep your original if you need to copy text
How to use the Compress PDF
- Open the Compress PDF and drop your PDF file(s).
- Pick the pages or options you need.
- Download the new PDF — your document never leaves your browser.
Compress PDF FAQ
How do I reduce a PDF to under 1 MB or 500 KB?
Start with the Recommended setting. If it is still too big, choose Strong or switch to greyscale for black-and-white scans.
Will the text in my PDF still be readable?
Yes, the Recommended setting keeps text sharp. Very strong compression can make small print fuzzy, so check the result before submitting.
Why can’t I select text after compressing?
The compressor turns each page into an optimised image, which is what makes the file small. Keep your original if you need to copy text.
