Compress a PDF to 100 KB
Application portals often limit documents to 100 KB. Bring your certificate, mark sheet or ID proof under the limit while keeping it readable.

How to get under 100 KB
- Choose the PDF of your document.
- Keep the target at 100 KB.
- Tick Black and white if the document has no colour stamps or photos you must keep, then select Compress PDF.
Start from a good scan
The smaller the limit, the more the starting scan matters. Place the document flat on a dark table, take the photo in daylight straight from above, and crop off the background before creating the PDF with JPG to PDF. A clean single page compresses to under 100 KB and stays readable.
Multi-page documents
A 100 KB limit leaves very little room per page for long documents. Upload only the pages the form asks for, using split PDF, or check whether the portal allows a larger size for multi-page files.
What fits in 100 KB
| Document | Usually fits? |
|---|---|
| 1-page certificate, black and white | Yes, clearly readable |
| 1-page colour certificate with seals | Yes, slightly softer |
| 2 to 3 pages, black and white | Usually, with small text still readable |
| 5 or more pages | Often too small to stay readable |
Step by step for a scanned mark sheet
- Photograph or scan the mark sheet flat and crop to the paper.
- Create the PDF with JPG to PDF, choosing A4 and no margin.
- Compress it here with Black and white turned on.
- Open the result and zoom into the roll number and marks to check they are readable.
Questions
Is the document uploaded?
Your files never leave your device. The conversion runs inside your browser, so nothing is uploaded to a server and there are no daily limits.
Will the portal accept it?
The result is a normal PDF. Check the size shown under the result is below the limit before uploading.
Why is my text not selectable afterwards?
To reach 100 KB, pages are saved as images. That does not matter for scanned certificates, which were images to begin with.
