It is 11 pm. You have finished writing and checking your TMA sheets. You open the portal, pick your file and press upload. The progress bar fills halfway and stops. You try again. Same thing. Now you are worried about missing the deadline.
Here is the good news. Most NIOS TMA PDF problems are really scanning problems: the file is too big, too dark, or has the wrong pages in it. All of these can be fixed in a few minutes with your phone.
This post covers only the scanning and PDF part. For the whole process from start to finish, follow our step-by-step NIOS TMA submission guide.

Before You Scan: 5-Minute Checklist
Five minutes here can save you an hour of rescanning later.
- Front page on top. Every subject needs its own front page. If yours is not ready, use our NIOS TMA front page format with free PDF.
- Pages in order, with page numbers at the bottom.
- A dark enough pen. Light ink and pencil often fade away in a scan. Dark blue or black works best.
- Good light. Daylight near a window is ideal.
- A flat surface. A table, not your bed. Curved pages scan badly.
- Handwritten answers only. NIOS does not accept typed or printed TMAs.
How to Scan Your NIOS TMA With a Phone
Free scanning apps are already on many phones, or you can install one free. Common examples are the scan option in Google Drive, Microsoft Lens and Adobe Scan. None of them is official or required by NIOS; use whichever you find easiest.
Open the scan option
Open your scanning app and choose the scan or document option, not the normal photo mode.
Start with the front page
Lay the subject’s front page flat and hold your phone straight above it.
Fix the edges
Let the app find the edges of the page. If the box is off, drag its corners to the edges of the paper.
Choose grayscale
Grayscale keeps the paper light and your handwriting clear, and makes the file smaller than colour. Black-and-white works too, but only if your ink stays dark; harsh filters can wash out light blue writing.
Scan the rest of the subject
Scan every page in order. Look at each one and rescan any page that is blurry or cut off.
Save as PDF and start the next subject
Save the pages as one PDF, give it a clear name, then start a fresh scan for the next subject.
Harsh from Nagpur scanned his TMA at 10:30 pm under a tube light. His shadow fell across every page, his English TMA came out grey and blotchy, and one answer could not be read at all. He rescanned the next morning beside a window. The handwriting was sharp, and the file came out smaller too.
Why You Should Scan, Not Take a Photo
A normal photo captures everything: the table, your shadow, creases in the paper and a lot of colour detail you do not need. That makes the file big and harder to read.
Scan mode crops away the background, straightens the page, brightens the paper and darkens your handwriting. With less colour and noise in the image, the PDF also ends up much smaller.
How to Make Your NIOS TMA PDF Smaller
If your file is too big, you can usually fix it inside your scanning app:
- Use grayscale instead of colour. Handwriting does not need colour, and this alone can shrink the file a lot. Try black-and-white only if your writing still looks dark and complete.
- Pick medium quality. High quality is not needed. Your handwriting stays readable.
- Scan at a normal resolution, not the highest setting the app offers.
- Delete blank pages, such as the back of a sheet you scanned by mistake.
After saving, check your file’s size in the app or your phone’s file manager, then compare it with the maximum size shown on your NIOS upload page. That limit can change, so always go by what your own screen says.
A Warning About Online PDF Compressors
When a file is too big, many people search for an online PDF compressor. Be careful. Your TMA carries your name and enrolment number, and once you upload it to an unknown website, you have no idea who keeps a copy. It is safer to use the quality or size setting inside your scanning app, so your document never leaves your phone.
Name Your Files Clearly
With files called “Scan 1”, “Scan 2” and “Scan 3”, it is easy to upload Maths under Science. Rename each file as soon as you save it, using this pattern:
SubjectName_SubjectCode_TMA, for example English_202_TMA. Use your own subject name and code from the top of that subject’s question paper. Some learners add their enrolment number too. Any pattern works, as long as the subject code is in the name.
NIOS TMA Upload Errors and How to Fix Them
You upload your TMA on the learner dashboard at sdmis.nios.ac.in. Find your problem below.
The file is too large
Rescan in grayscale at medium quality, delete any blank pages, and check the new file size against the limit on your upload page.
The upload keeps failing or stops halfway
This is usually the network. Move closer to your Wi-Fi router, or switch between Wi-Fi and mobile data. A smaller file also uploads faster. If it keeps failing at night, try again in the morning when the portal is less busy.
Wrong file type
The portal expects a PDF. A photo or any other file type may be rejected. Open the scan in your app and save or export it as a PDF.
Several subjects in one PDF
Meenal from Ludhiana scanned all five subjects into one long PDF. The file was huge and would not upload, and even if it had, it would have been wrong, because NIOS needs one PDF per subject. She split it into five files, each starting with its own front page. All five went through in about ten minutes.
It uploaded but the subject still shows as pending
Wait a few minutes, then log out and log back in. If the subject still shows as pending, do not keep uploading again: the official NIOS TMA booklet says a TMA can be uploaded only once. Take a screenshot of the status and contact your study centre (AI) or NIOS Regional Centre.
The portal is slow or will not open
The portal often slows down near deadlines. Try a different browser, or a laptop if you have one. If you cannot log in at all, follow our NIOS SDMIS login guide. And next time, upload in the morning or afternoon, a few days before your NIOS TMA last date.
Final Checks Before You Close the Portal
Do not rush this part. Make sure every subject shows as uploaded, take a screenshot of the page and save it somewhere safe. Keep your handwritten sheets until your result is out, in case you ever need to rescan.
Common Mistakes
- Taking a photo instead of scanning. Fix: use the scan option in a free app.
- Putting several subjects in one PDF. Fix: one PDF per subject.
- Leaving out the front page. Fix: add a front page at the start of every subject.
- Writing with a light pen. Fix: use dark blue or black ink.
- Uploading on the last night. Fix: upload in the daytime, a few days early.

Frequently Asked Questions
Which app should I use to scan my NIOS TMA?
Any free scanning app works, for example the scan option in Google Drive, Microsoft Lens or Adobe Scan. NIOS does not require any particular app.
What is the maximum file size for a NIOS TMA PDF?
The limit is shown on your upload page on the learner dashboard, and it can change, so always check your own screen. If your file is too big, shrink it using your scanning app’s settings.
Can I upload all my subjects in one PDF?
No. You need one PDF per subject, and each PDF should start with that subject’s front page.
Can I upload a typed TMA?
No. NIOS accepts only handwritten TMAs, so every answer must be in your own handwriting.
I uploaded the wrong file. What should I do?
The official NIOS TMA booklet says a TMA can be uploaded only once and cannot be re-evaluated after it is checked. So if you uploaded the wrong file, do not keep trying to upload again. Take a screenshot and contact your study centre (AI) or NIOS Regional Centre straight away, and check your dashboard in case a correction option is shown for your session.
My scan looks dark and unclear. What should I do?
Rescan in daylight on a flat surface, use the grayscale setting, and make sure your hand or phone is not casting a shadow on the page. If the writing looks faded, switch off any strong black-and-white filter.
Do all NIOS learners have to submit a TMA?
No. Only Stream 1 learners submit a TMA. Our complete NIOS TMA guide explains who needs to do it and why.
What is the last date to upload the NIOS TMA?
The last date is usually 31 January for the March-April exam and 31 July for the September-October exam. For the March-April 2027 exam, that means 31 January 2027. Always confirm the current date on your dashboard.
Scan one subject now as a test, check its size against your upload page, and fix the settings before you scan the rest. Then follow the NIOS TMA submission guide to upload. For more NIOS help, visit NIOS Info.
