It is a range, not a limit

Every certificate NEET asks for must be a PDF between 50 KB and 300 KB. Almost every compression tool online treats 300 KB as a ceiling and squeezes as far below it as possible — which can push your file under 50 KB and get it rejected for being too small. This tool aims for the middle of the range and tells you plainly if it cannot get there.

The bulletin also repeats one word for nearly every document: clearly legible. A file that meets the size requirement but cannot be read still fails at verification, so check the certificate number, dates and seals in the finished file before you upload it.

Documents this covers

Taken from the NEET (UG) 2026 Information Bulletin, Chapter 3, Step 2(d).

Document	Format	Size	Item
Category Certificate	PDF	50 KB – 300 KB	iv
Class X or Equivalent Certificate	PDF	50 KB – 300 KB	v

CGPA Conversion / Equivalent Certificate	PDF	50 KB – 300 KB	vii
PwD / PwBD / UDID Certificate	PDF	50 KB – 300 KB	ix
Address Proof (Present and Permanent)	PDF	50 KB – 300 KB	x
NRI / OCI / Foreigner Certificate	PDF	50 KB – 300 KB	xi
Scribe's Qualification Certificate	PDF	50 KB – 300 KB	xiii
Undertaking for Using Your Own Scribe	PDF	50 KB – 300 KB	xiv
Certificate of Physical Limitation to Write	PDF	50 KB – 300 KB	xvi

NEET sets no filename requirement. Unlike some other examinations, the bulletin does not tell you what to call your files. If you have seen advice about exact filenames for NEET, it is not from this bulletin. What the bulletin does insist on, repeatedly, is that every document is clearly legible.

Preparing a certificate that is too large

A colour scan of a Class X certificate at 300 DPI is commonly 2–4 MB, so reaching 300 KB means cutting it to under a tenth. That is normal. If the result comes out hard to read, work in this order:

Convert to grayscale first. A certificate is dark text on pale paper and the colour data is mostly waste. Our grayscale tool removes it before compression, leaving more room for detail.
Then bring it into the range with the tool above.
Read the result. If the certificate number, your name, the date or the issuing authority are not clear, rescan at 150–200 DPI in grayscale rather than compressing a colour scan harder.

If a certificate spans several pages, merge them into one PDF first. If a scan came out sideways, rotate it before compressing. If you only have a photograph of the certificate, convert it to PDF first — the bulletin requires PDF for all of these.

The image uploads are different

The photograph, signature and finger and thumb impressions are JPG/JPEG images, not PDFs, and have their own size ranges. This tool does not handle them.

Upload	Format	Size
Passport size photograph	JPG/JPEG	10 KB – 200 KB
Signature	JPG/JPEG	10 KB – 100 KB
Scribe's signature	JPG/JPEG	10 KB – 100 KB
Left and right hand fingers and thumb impressions	JPG/JPEG	see note below
Identity proof (non-Aadhaar route)	JPG/JPEG or PDF	see note below

The bulletin gives two different sizes for two of these. For the fingers and thumb impressions, item (iii) of the upload list says 10 KB to 200 KB, while the detailed section later in the same chapter says the file size must be between 50 KB and 300 KB. For identity proof, item (viii) says JPG/JPEG between 10 KB and 200 KB, while item (xv) — seven lines further down the same list — says 50 KB to 300 KB. Both figures are in the official bulletin. The safe course is to land in the overlap, 50 KB to 200 KB, which satisfies either reading, and to check what the portal accepts at upload time.

The bulletin gives no pixel dimensions. Not for the photograph, not for the signature, not for anything — we searched the whole document. If you have seen a specific pixel size or DPI quoted for NEET, it did not come from this bulletin.

Photograph rules

Colour or black & white JPG/JPEG, 10 KB to 200 KB.
80% of the image area must be your face, visible including ears, without a mask, against a white background.
Spectacles are allowed only if you use them regularly.
Polaroid and computer-generated photographs are not acceptable.
A photograph that appears fabricated, de-shaped, hand-made or computer-made means rejection and is treated as Unfair Means.
A live photograph is captured during the application and matched against the Aadhaar database. If it does not match, you must upload an attested certificate with a recent photograph per Annexure VI.
The same passport-size photograph must be used on the application and pasted on the attendance sheet at the centre. Keep 6–8 passport and 4–6 postcard size prints.

Note that the postcard size (4″×6″) photograph is a physical print to carry, not an upload. It does not appear anywhere in the bulletin's upload list.

Frequently asked questions

What size should NEET certificates be?

PDF format, between 50 KB and 300 KB. Note that this is a range: a file compressed below 50 KB is rejected just as an oversized one is.

Does NEET require a specific filename?

No. Unlike some other examinations, the NEET bulletin sets no filename requirement for uploaded documents. It does require every document to be clearly legible.

My certificate is a JPG. Can I use it?

Not directly. The bulletin requires these documents in PDF format. Convert your image to PDF first using our JPG to PDF tool, then bring the PDF here.

My scan is under 50 KB already. What do I do?

It is below the minimum and compression only makes files smaller. Rescan the certificate at a higher resolution, or in colour rather than pure black and white, so there is more detail to work with.

Why does my compressed certificate look unreadable?

Compression trades detail for size. The bulletin requires every document to be clearly legible, so if the certificate number, dates or seals cannot be read, convert to grayscale first and then compress rather than compressing a colour scan harder.

Can I correct a document after submitting?

The bulletin warns that the facility for correction will not be given for the photograph, signature and finger and thumb impressions. Check everything before you submit.

Are my certificates uploaded to your server?

No. Compression runs inside your browser on your own device. Your certificates carry your name, address and identity details, and none of it is transmitted anywhere.
