How to convert UPSC signature to 100 KB
- Sign three times, one below the other, in black ink on plain white paper.
- Scan or photograph the sheet, crop to the ink, and drop it here.
- Rename the download to "signature" before you upload it.
What happens to your file
UPSC asks for a signature file of 20 to 100 KB with both its height and width between 350 and 500 pixels, in black ink on plain unruled white paper. It says outright that applications whose signature files do not meet the specification will be rejected, so the numbers are worth getting right.
The part that surprises people: you must sign three times, one below the other, in a single image. The instruction says the file must contain exactly three signatures, and the button on the application form reads "Upload Triple Signature". UPSC’s older instruction sheet from July 2025 is still published and still says one signature; the February 2026 sheet and the live form both say three.
The file name matters too, which is unusual. UPSC requires the signature file to be called literally "signature" and the photograph "photo", and says a document will not be uploaded if any other file name, format or size is used.
This page compresses to just under 100 KB and leaves the file there, rather than shrinking as far as it can, because 20 KB is a floor and not a suggestion. If your scan is already smaller than 20 KB it will come back unchanged and still be too small — the fix for that is to rescan at a higher resolution, since no tool can honestly add detail that was never captured.
What UPSC no longer asks for is worth as much as what it does. There is no requirement to print your name or the date on the photograph, no "not older than 10 days" rule, and no 350 × 350 to 1000 × 1000 pixel range for it. None of that appears in any current UPSC document or in the live form’s own validation, though coaching sites still publish all three.
Questions
How many signatures does UPSC want?
Three, one below the other, in one image — exactly three, according to the February 2026 instruction sheet and the application form’s own "Upload Triple Signature" button. The July 2025 sheet still on the site says one; the triple rule is the current one.
What is the UPSC signature size?
20 KB to 100 KB, JPG or JPEG, with height and width both between 350 and 500 pixels, black ink on plain unruled white paper. The file must be named "signature".
What is the UPSC photo size?
20 KB to 200 KB, JPG or JPEG, file named "photo", on a plain white background, with the face covering at least 75% of the area. The photograph is not to be signed. A live capture is taken as well and matched against it; if they do not match you cannot proceed.
Do I need my name and the date printed on the photo?
No. That rule, along with "not older than 10 days", is from an older cycle. It appears in no current official UPSC document and in none of the live form’s validation, although many coaching sites still repeat it.
My signature file is under 20 KB. What do I do?
Rescan it at a higher resolution. Compression can only make a file smaller, and adding bytes to a small image would be inventing detail that was never there. Scanning at 300 DPI in colour instead of a low-resolution black-and-white setting is usually enough on its own.
Should I sign in capitals?
UPSC does not say anything about capitals either way, unlike the banking and railway forms which ban them outright. Sign the way you normally sign, which is what a signature is for.
Is it really not uploaded?
For JPG, PNG and WebP, correct — the page works with your network unplugged. The privacy sweep in our test suite asserts that no host is contacted.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
