Almost every online exam application — SSC, UPSC, the bank (IBPS/SBI) exams, RRB railways, NEET, university admissions — rejects your photo or signature unless it matches an exact pixel size AND sits inside a strict file-size range in KB. “Photo must be 20–50 KB”, “signature must be 10–20 KB”: it’s the single most frustrating step of any form. Here’s how to get it right in seconds, free and without storing your documents anywhere.
Drop in your photo or your scanned/photographed signature. It loads instantly and stays private.
Choose Photo, Signature, Passport or Thumb — or pick Custom and type the exact pixels and KB range your form lists.
The tool resizes to the exact dimensions and automatically tunes the quality to land inside the required KB range.
Save the ready-to-upload JPG at the precise dimensions and file size your portal accepts.
Why exam portals are so strict
Government and competitive-exam portals store millions of applications, so they cap each photo and signature to keep their databases small and their pages fast. That’s why they specify both a pixel size (so every photo prints the same on your admit card) and a KB range (a minimum so the image isn’t unreadably blurry, and a maximum to save space). Miss either and the upload is rejected — usually with a vague error that doesn’t tell you what’s wrong.
The most common specs
Specs vary by exam, so always check your own notification, but these cover the majority of Indian forms:
- Photo: 200×230 pixels, 20–50 KB, JPG.
- Signature: 140×60 pixels, 10–20 KB, JPG.
- Passport size: 3.5×4.5 cm (about 413×531 px at 300 DPI).
- Thumb impression (some forms): 140×60 pixels, 20–40 KB.
How hitting an exact KB actually works
Resizing to the right pixels is easy; the hard part is the file size. A JPG’s size depends on its quality setting — lower quality, smaller file. Instead of guessing the quality and re-exporting again and again, this tool resizes your image once and then automatically searches for the quality that lands the file inside your target KB range. You get a file that’s under the maximum but still clear enough to pass the minimum, in one click.
Tip: Scan or photograph your signature on plain white paper in good light, then use the “Fit (white background)” option so the whole signature stays visible without being cropped.

How do I make my photo exactly 20 to 50 KB?
Pick the Photo preset (or enter 20 and 50 as the min/max KB) and the tool automatically compresses your resized photo to land inside that range — no trial and error.
Is my photo or signature uploaded to a server?
No. Everything happens securely, so your documents are never stored — important for sensitive exam photos.
Which exams does this work for?
Any form that lists a pixel size and KB range — SSC, UPSC, IBPS/SBI and other bank exams, RRB railways, NEET and university admissions. Use Custom for your form’s exact requirement.
What if my form needs a different size?
Choose Custom and type the exact width, height and KB range from your exam notification — the tool will match it precisely.
