What is the PDF size limit for NEET UG certificates?

In recent cycles, NEET UG has asked for certificates as a PDF between 50KB and 300KB. Always confirm in the current information bulletin before uploading — NTA can change limits between sessions.

My PDF is in range but the portal still says “upload a valid PDF”. Why?

This usually means the file is a renamed image, is password-protected, or was saved by an app the portal can't read. Re-saving it through the compressor on this page produces a clean, standard PDF that portals accept.

Can I do this on my phone?

Yes. This page works in your mobile browser. If you're filling the form on your phone, the free FramePDF Android app can also make PDFs smaller and combine pages offline.

Is it safe to compress my certificate here?

Yes. Compression runs entirely in your browser — the file is never uploaded to any server.

Target size

This form needs at least 50KB — we'll warn you if the result goes under.

Black & white — best for scanned certificates; much smaller files

Step by step

1Collect each document as its own PDF — NEET has a separate upload slot for each.
2Drop one PDF at a time into the compressor above (preset to 280KB).
3If a document has a front and back, merge both sides into one PDF first, then compress.
4Open the compressed file and zoom in on names and numbers before uploading.

Front and back on one PDF

Address proofs like Aadhaar have two sides. Use Merge PDF to combine them into one file, then compress the merged file so the 300KB budget is shared across both pages.

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.
