Quick answer: To compress a PDF to 200 KB, open it here, keep the 200 KB target (or pick 100, 300 or 500 KB) and download the result. The tool shrinks the images inside first and only turns pages into images if that is not enough; one to three scanned pages usually stay clearly readable at 200 KB. Nothing is uploaded.
The form says "PDF, max 200 KB" and your scan is 3 MB. Keep the 200 KB target and the PDF is shrunk step by step until it fits, as clear as the limit allows.

How to compress PDF to 200 KB
- Choose the PDF: a scanned certificate, ID proof, admit card or signed letter.
- Keep 200 KB, or pick the size the form asks for: 100, 300 or 500 KB.
- Press Compress to target and wait while it tries the gentlest method first.
- Zoom in on the result to check names and numbers, then download it.
What fits in 200 KB
200 KB is twice the room of the common 100 KB limit, which is the difference between "readable" and "clear" for most scans:
| Document | At 200 KB |
|---|---|
| Typed PDF from Word or Google Docs | Usually already under, text stays selectable |
| 1 scanned page (certificate, ID card, letter) | Clear, including small print |
| 2 to 3 scanned pages | Readable; fine print a little soft |
| 5 or more scanned pages | Soft; choose 500 KB if allowed, or upload fewer pages |
These are typical results; a colour photo of a document with a shadowy background needs more space than a clean flatbed scan.
How it gets under 200 KB
- The photos inside the PDF are re-saved smaller (up to about 1400 pixels, at a lower JPEG quality). Text, links and layout stay as they are.
- If the file is still too big, each page is redrawn as an image at 120 dpi, then 96, 72, 60 and finally 50 dpi, with the quality lowered a little at each step.
It stops at the first step that fits and tells you which one it used. After step 2 the text is part of the picture, so it can no longer be selected; forms that only need to see the document do not mind.
Make a clearer 200 KB file
- Drop the colour: if the form accepts black and white, run Grayscale PDF first. Grey pages leave more of the 200 KB for detail.
- Upload only the pages asked for: remove the back of a certificate or a blank page with Delete pages.
- Photo of a document? Crop away the table around the paper before making the PDF with JPG to PDF.
Your documents are compressed by your own browser and never uploaded to us, so there is no copy of your certificates on anyone's server.

Frequently asked questions
How do I reduce a PDF to 200 KB?
Open it here, keep the 200 KB target and press Compress to target. The images inside are shrunk first; if that is not enough, pages are converted to images at a lower resolution until the file is under 200 KB.
Will the document still be readable?
For one to three scanned pages, yes. Longer documents get soft at 200 KB; pick 300 or 500 KB if the form allows, or upload fewer pages.
Why is my typed PDF not smaller?
It is probably already under 200 KB: text takes very little space. In that case the original is kept unchanged.
Is my document uploaded?
No. The PDF is compressed in your browser on your device.
