Compress your JEE Main PDF
Preset to 280KB, with a 50KB minimum for JEE Main. Runs in your browser — nothing is uploaded.
Step by step
- 1Scan or photograph the certificate flat, in good light, with all four corners visible.
- 2If it's a photo, convert it with JPG to PDF first.
- 3Drop the PDF into the compressor above — it's preset to 280KB so you land safely inside 50–300KB.
- 4Check the result opens and the certificate number is readable, then upload.
Why 280KB and not 300KB?
Some portals count 1KB as 1,000 bytes and others as 1,024. Aiming a little under the ceiling avoids a rejection on a technicality, while still giving the scan plenty of quality.
OBC-NCL certificate date
For the 2026 cycle, NTA asked for OBC-NCL certificates issued on or after 1 April 2026. Compressing won't help if the certificate itself is out of date — check the issue date before you upload.
Common reasons uploads get rejected
- Going under the minimum. A 30KB certificate fails just like a 400KB one — NTA checks both ends of the range.
- Uploading a JPG renamed to .pdf. The portal checks the file itself, not just the name. Convert properly with JPG to PDF.
- Sideways or upside-down scans. Rotate before you compress so the verifier can read it.
- Blurry text after compressing too hard. If the certificate number isn't readable, you've gone too far — aim for 200–280KB.
