How to use it
- 100 KB is already selected — just tap “Select PDF” and choose your file.
- Turn on “Black & white” if the document is mostly text: the file gets smaller and the text cleaner.
- Wait while each page is compressed to fit 100 KB — you'll see the progress page by page.
- Check the new size and tap “Download PDF”.
Where is a 100 KB PDF needed?
Some recruitment, scholarship and admission portals limit each document — caste, income, EWS, domicile or disability certificates, NOCs and ID proofs — to about 100 KB. Limits differ between portals and change from year to year, so always check the exact figure in the official notification.
How much fits in 100 KB?
The size budget is shared by every page, so the number of pages decides how sharp each one can be. Simple arithmetic shows why one-page documents work best:
| Pages | Space per page | What to expect |
|---|---|---|
| 1 | about 100 KB | Clear, even in colour |
| 2 | about 50 KB | Readable; Black & white recommended |
| 3 – 4 | 25 – 33 KB | Use Black & white and check small print |
| 5 or more | under 20 KB | Text may blur — upload only the pages you need |
Tips for a readable 100 KB PDF
- Turn on Black & white for typed or printed documents — paper becomes pure white and costs almost nothing.
- Scan or photograph only the document, without the table around it, and remove blank back pages.
- If the form also accepts JPG for this document, a single image may look sharper — try Compress Image to 100 KB.
- Allowed a little more? 200 KB gives every page twice the room.
Why is my PDF over 100 KB in the first place?
Phone cameras and scanner apps save every page as a high-resolution colour photo — perfect for printing, but far more detail than an online form needs. Even a well-compressed page of that kind is usually several hundred KB. To reach 100 KB the page is redrawn at a lower resolution, which still keeps printed text readable on screen.
Check before you upload
- Open the downloaded PDF and zoom in on your name, roll number and certificate number — they must be readable.
- Make sure every page is there and the right way up.
- Some portals reject file names with spaces or symbols. If yours does, rename the file to something simple such as caste_certificate.pdf.
