Document Upload Size Guide: PDF Limits for Marksheets, Certificates and IDs
Most size guides only cover photos and signatures. But the upload that fails most often is the document: a marksheet, a caste certificate, an ID card or a bank passbook.
Each portal sets its own PDF limit. Some want 200KB. Some allow 2MB. A few even reject files that are too small.
So we went to the source. For every limit below, we checked the official notice, FAQ or portal page first. Where we could only find the number on coaching sites, we say so clearly.
Last verified: November 2026. Limits change every season, so always glance at the latest notice before you upload.
Quick answer: document size limits at a glance
| Portal | Document | Format | Size limit |
|---|---|---|---|
| NEET UG (NTA) | Class 10 certificate, category, PwBD, address proof | 50KB to 300KB | |
| UPSC (OTR and CSE) | Photo ID card | See UPSC section | 20KB to 200KB or 300KB |
| National Scholarship Portal | Every supporting document | PDF or JPEG | Up to 200KB each |
| myAadhaar document update | Proof of identity and address | PDF, JPEG or PNG | Under 2MB each |
| Passport Seva (GPSP 2.0) | All supporting documents | 1MB in total | |
| Indian Visa Online | Each supporting document | 10KB to 500KB |
The pattern is clear. Exam and scholarship portals are strict, usually 200KB to 300KB. Identity services like Aadhaar are far more relaxed.
Why document limits differ from photo limits
A photo is one small image. A document is a full page, often A4, with text that must stay readable.
That is why portals give documents more room. NEET, for example, allows certificates up to 300KB while its passport photo stops at 200KB.
Still, a phone scan of a single page easily lands between 500KB and 1.5MB. In our own tests, one A4 page scanned in colour at 150 DPI weighed 541KB. At 300 DPI it reached 1,507KB. So almost every scanned document needs compressing before it fits.
NEET UG: certificates between 50KB and 300KB
NTA asks for several documents in PDF form during NEET UG registration. Coaching sites that reproduce the NEET UG 2026 Information Bulletin agree on one range for all of them: 50KB to 300KB.
That range covers:
- Class 10 passing certificate and marksheet
- Category certificate (SC, ST, OBC NCL or EWS)
- PwBD or UDID certificate
- Present and permanent address proof
- Citizenship or embassy certificate for NRI, OCI and foreign candidates
Physics Wallah’s summary of the 2026 rules says every certificate must be a PDF between 50KB and 300KB. We could not open the bulletin PDF itself, so treat this as widely reported rather than quoted from NTA. Check the bulletin on neet.nta.nic.in before you submit.
Watch the minimum. A 50KB floor catches people out. A clean digital certificate exported straight from DigiLocker can be only 20KB to 40KB, which the portal rejects as too small. If that happens, scan the paper copy at 200 DPI in colour instead, then compress it to around 250KB.
UPSC: the photo ID card
UPSC asks for one document at registration: a scanned government photo ID such as Aadhaar, PAN, passport, voter card or driving licence.
This is where the internet disagrees. For years, guides listed the ID as a PDF between 20KB and 300KB. But for the 2026 cycle, ExamDetail’s UPSC size page cites UPSC Examination Notice No. 05/2026 and the portal instructions dated 4 February 2026. According to them, the photo ID is a JPG between 20KB and 200KB.
Our advice is simple. Read the “Instructions for uploading documents” link on upsconline.nic.in for your exam, and follow the format it names. If it says JPG, use our PDF to JPG tool to turn your ID into an image under 200KB. If it says PDF, aim for 250KB or less with our PDF compressor.
Later documents for the Detailed Application Form follow the rules printed in that form, so check them again at that stage.
National Scholarship Portal: 200KB per document
NSP is the strictest common portal for documents. The official FAQ for the disability scholarship schemes says each document must be a PDF or JPEG and must not exceed 200kb. It also warns that unreadable uploads are liable to be rejected.
That 200KB limit applies to the documents students upload most:
- Income certificate
- Caste or community certificate
- Fee receipt and bonafide certificate
- Previous year marksheet
- Bank passbook front page
Individual schemes can differ, so read the upload screen. But 200KB is the safe target, and it is exactly what our homepage tool is built for.
myAadhaar: under 2MB per document
Aadhaar is the relaxed one. UIDAI’s own FAQ says to upload your identity and address documents with a size less than 2 MB, in JPEG, PNG or PDF format.
Most phone scans already fit. You only need to compress if your PDF has many pages or very large photos. Even then, aim for clarity over a tiny size. UIDAI staff read these documents by eye, so a sharp 1MB file beats a blurry 100KB one.
Passport Seva: 1MB for everything combined
The Passport Seva limit catches people out because it is a total, not a per file limit. The Embassy of India’s guide to the new GPSP 2.0 applicant portal says the maximum size allowed is 1 MB, and the total of all uploaded documents should be not more than 1 MB. Every file must be a PDF.
So split your budget before you start:
| Documents you upload | Target per PDF |
|---|---|
| 2 documents | about 480KB each |
| 3 documents | about 320KB each |
| 4 documents | about 240KB each |
| 5 documents | about 190KB each |
Our compressor lets you type any of these targets with the Custom option.
Indian Visa Online: 10KB to 500KB per PDF
The official Indian Visa Online document page asks for PDF files with a minimum of 10 KB and a maximum of 500 KB. It also says every document, including business cards and invitation letters, must be in English.
A 500KB ceiling is roomy for one or two pages. Longer letters or bank statements usually need one pass through a compressor.
How to get your document under any limit
The steps are the same whatever the portal.
- Check the format first. If the portal wants JPG and you have a PDF, convert it with our PDF to JPG tool. If you have photos of pages and need a PDF, use JPG to PDF.
- Leave a margin. Some portals count 1KB as 1,000 bytes, others as 1,024. Aim about 5 percent below the limit, for example 190KB for a 200KB cap.
- Compress in your browser. Open our PDF compressor, choose your target, and add the file. It keeps real text sharp and shrinks only the images, and your marksheet never leaves your device.
- Zoom in before you upload. Check names, roll numbers and dates. If anything blurs, try a slightly higher target or a cleaner scan.
If you are scanning with a phone, our guide on scanning documents to a PDF under 200KB shows the settings that keep files small from the start.
How many pages fit in each limit
Multi page uploads are where people struggle most. Here is a rough guide for scanned text pages, based on our own compression tests:
| Size limit | 1 page | 2 pages | 4 pages |
|---|---|---|---|
| 200KB | Easy, sharp | Fine in greyscale | Tight, use black and white |
| 300KB | Easy, sharp | Easy | Fine in greyscale |
| 500KB | Easy, colour | Easy, colour | Easy |
| 1MB | Easy, colour | Easy, colour | Easy, colour |
In our testing, a 2.48MB phone scan came down to 172KB, and a 10.02MB multi page scan reached 191KB. Text stayed readable in both. To see why scans start out so heavy, read why your PDF is so large.
Common upload errors and quick fixes
“File size exceeds the limit.” Compress to about 5 percent under the cap. Then check the size in your file manager, not just in the tool.
“File size is too small.” This happens on portals with a minimum, like NEET’s 50KB. Rescan at 200 DPI in colour, or compress to a higher target such as 250KB.
“Invalid file format.” The portal wants a different type. Convert PDF to JPG or JPG to PDF before uploading. Renaming the file extension does not convert it.
“Upload failed” with no reason. Remove the password from protected PDFs, shorten the file name, and try again on a desktop browser if your phone keeps failing. Our guide to compressing a PDF on your phone covers more mobile fixes.
FAQ
What is the standard PDF size for online forms in India?
There is no single standard. Exam and scholarship portals usually allow 200KB to 300KB per document, while Aadhaar allows up to 2MB. Always read the limit printed on the upload screen or in the official notice for your form.
What size should a marksheet PDF be for NEET?
Coaching sites that reproduce the NEET UG 2026 bulletin list 50KB to 300KB for the Class 10 certificate and marksheet. Aim for about 250KB. That stays under the cap and well above the 50KB minimum.
What is the document size limit on the National Scholarship Portal?
The official NSP FAQ for disability scholarships says each document must be a PDF or JPEG of no more than 200KB. Other schemes on NSP commonly use the same limit, so 190KB is a safe target.
How do I reduce a certificate PDF to 200KB without losing quality?
Use a compressor that keeps text as text and shrinks only images. Our homepage tool does this in your browser. Scanned certificates are images, so start from a clean, well lit scan for the sharpest result.
Why does a portal say my file is too small?
Some portals set a minimum size, such as 50KB on NEET, to block blank or broken uploads. Rescan the document at a higher resolution, or compress it to a target nearer the maximum instead of the smallest possible size.
Is the Passport Seva 1MB limit per file or for all files?
For the GPSP 2.0 applicant portal, the embassy guide says the total of all uploaded documents should not exceed 1MB. Divide that budget across your files before you compress them.
