Convert a photo to 20–50 KB
Many exam and job forms accept a photo only between 20 KB and 50 KB. Get yours inside the range in one step: never too big, never too small.
Which forms ask for 20–50 KB?
In our exam list (rules checked September 2026), photo: Army Agniveer, IBPS, SBI, RBI, TNPSC, TNUSRB, KPSC, TGPSC, MPSC, UPPSC, JPSC, UP Police, HSSC CET; left thumb: IBPS, SBI, RBI; signature: RPSC / RSSB, CGPSC.
Why the range has a minimum
A file under 20 KB is refused just like one over 50 KB: portals set a floor so photos stay readable. Compressors that only aim for a maximum can overshoot and land below it, which is why this page sets both ends.
How to land inside the range
Aim for the middle, about 35 KB, rather than exactly 50 KB, because some portals count a kilobyte as 1000 bytes and others as 1024. The size here is set to 45 KB with a 20 KB minimum, so the result fits either way. Crop to head and shoulders first so the KB go to your face, not the background.
Signature in the same range?
A clean signature on white paper is often only 3–8 KB, well under 20 KB. The tool raises the quality first and then adds invisible padding, so the file reaches 20 KB without changing how it looks.
Use cases
The most common exam range
Many forms want a photo between 20 and 50 KB. Get it into the range in one step, whichever side it started.
Checking both limits
A file that's 18 KB is rejected as surely as one that's 55 KB; this lands between them with room to spare.
Photo and signature together
Prepare the photo here and the signature at its own range, for forms that list both.
Questions
My photo is 12 KB. Can it become 20 KB?
Yes. The minimum is already set to 20 KB, so a small file is brought up to it, and a large one is brought down under 50 KB.
Does the pixel size matter too?
Often, yes: many forms also give a size such as 200 × 230 px or 3.5 × 4.5 cm. Open your exam's page, where both are set for you.
Which format should I use?
JPG. Almost every exam portal accepts only JPG or JPEG.
