How to resize a UPSC photo and signature
- Check the pixels first. Each side must be 350 to 1000 px. A phone photo is usually far bigger (ours was 3024 × 4032), so set something like 750 × 1000 in the image resizer (Dimensions) before you come back.
- Add the 750 × 1000 JPG to the box above and leave the target at 100 KB. That sits well inside 20–300 KB, so a few bytes either way cannot push it out.
- Press Compress & Download. Our test photo came back at 98,853 bytes and still 750 × 1000 px.
- Sign on white paper with a black pen, photograph it, and crop it so the short side is at least 350 px and the long side at most 1000 px. Run it through the same box.
- Upload the photo and the signature to the UPSC form. The download is named after the target you typed, such as 100kb-photo.jpg, so the two files are easy to tell apart.

UPSC photo upload errors and how to fix each
The form says the photo is smaller than 20 KB
You typed a target at the very bottom of the range. On our test, a 20 KB target saved 19,911 bytes, because the tool always stops at or under the target. Type 30 KB or more and the file clears the 20 KB floor.
The form says the image is larger than 1000 pixels
This editor shrinks pixels only when JPEG quality alone cannot reach the target, so a big photo can keep its size: a 3024 × 4032 photo at 100 KB stayed 3024 × 4032 (99,017 bytes). Resize to 1000 px or less on the long side in the image resizer, then compress here.
The signature is rejected for size in pixels
A signature cropped tight to the ink is often less than 350 px tall. Crop with a white margin above and below the ink instead, so the crop keeps at least 350 px on its short side.
I typed 300 KB but the file is much smaller
That is expected. At 300 KB our 750 × 1000 photo saved 132,114 bytes: the best JPEG quality the tool uses already fits, so it stops there. Anything from 20 KB to 300 KB is accepted, so the smaller file is fine.

750 × 1000 px · default 100 KB target
Same session, 1000 × 400 px signature scan (48,394 bytes): at 100 KB it saved 54,199 bytes, larger than the scan, because the tool saves at the best JPEG quality that fits the target rather than shrinking for its own sake; with 40 KB typed it saved 39,305 bytes. Both stayed 1000 × 400, and all three files sit between 20 KB and 300 KB. Tested on this page, 24 Oct 2026.
Where your UPSC photo and signature go
The resizing happens in your browser tab: the photo and the signature are drawn on a canvas on your phone or computer and saved from there, and the picture itself is not sent to StitchMagic. There is no phone number or sign-in step before the download, and the tool takes as many photos as you need.
UPSC’s FAQ does not mention live photo capture, and it sets the same 20–300 KB limits for the signature as for the photo, so one box on this page serves both files.
UPSC photo size and resize: questions
What is the UPSC photo size?
A JPG of 20 KB to 300 KB, at least 350 × 350 and at most 1000 × 1000 pixels, as UPSC’s OTRP FAQ (questions 43–44) states; we read it on 24 Oct 2026. If your exam notice gives other figures, follow the notice.
What is the UPSC signature size?
The same limits as the photo: JPG, 20–300 KB, 350 to 1000 pixels a side. UPSC asks for the signature on white paper, preferably in black ink.
How do I resize a UPSC photo to the right KB?
Set the pixels to 1000 or less on the long side first, then add the UPSC photo above, keep 100 KB and press Compress & Download. The result line shows the exact bytes; anything from 30,000 to 300,000 is safely inside the range.
Does this UPSC photo editor change the pixel size?
Only if quality alone cannot reach the target, and then it scales the whole photo down in 15% steps without cropping. To meet the 1000-pixel limit, use the image resizer first.
Why does UPSC reject a photo I made at 20 KB?
The file came out just under UPSC’s 20 KB minimum. A 20 KB target gave 19,911 bytes on our test, so type 30 KB or more.
Can I use a 3/4 size or passport size photo for UPSC?
UPSC’s FAQ sets limits in pixels and KB, not a print size. A scan of a 3/4 or passport size print passes that check once it is 350 to 1000 pixels a side, 20–300 KB and JPG; how recent the photo must be and what it must show are set in your exam notice.
