Compress PDF to 100 KB, 200 KB or any size
Choose the maximum size you need — like 100 KB for a form upload — and get a smaller PDF. It only ever gets smaller, and nothing is uploaded.
Compress PDF FAQ
How do I compress a PDF to 100 KB?
Add the PDF, tap 100 KB (or type 100 and choose KB) and click Compress PDF. You get a file of 100 KB or less when that is possible; very long documents may need a larger size.
Why is the text not selectable after compressing?
When lossless compression is not enough to reach your size, pages are turned into images at the highest quality that fits. The pages look the same, but the text can no longer be selected.
Can the compressed PDF be bigger than the original?
No. The tool only gives you a result that is smaller than your original file.
What does Black & white do?
It removes colour, which makes scanned pages and shipping labels much smaller at the same sharpness.
Is it safe for ID proofs and certificates?
Yes. Compression runs in your browser, so the file never leaves your device.
