Can a passport photo really be 10 KB?

Only at small pixel dimensions. A 200×230 px headshot can pass 10 KB and still be recognisable, but a 600×800 px one cannot. Reduce the dimensions first and the byte target stops fighting you.

Should a signature be JPG or PNG at this size?

JPG. PNG stores each pixel losslessly, so a scanned signature with paper texture is often three to five times larger than the same image as a JPG at quality 70.

Resize an image to 10 KB

10 KB is about as small as a legible photo gets — it is usually asked for signature strips and thumbnail-sized ID crops. Drop your photo in below — the target is already set to 10 KB, and everything runs inside this browser tab, so the image never leaves your device.

How to get a photo under 10 KB without it turning to mush

Crop before you compress

Empty background costs bytes. Cropping tight on the subject leaves more of the size budget for the detail that matters.

Match the required dimensions

Most forms cap both KB and pixels. Set the dimension preset here as well so a 10 KB file is not rejected for being the wrong shape.

Use JPG for photos

PNG stores photos far less efficiently. Choosing JPG output often reaches the target with visibly better quality.

Who asks for 10 KB?

10 KB is almost always a signature field, not a photo field. Indian recruitment portals, bank KYC forms and university admission systems ask for a signature strip between 4 KB and 12 KB, and a few older state portals still cap thumbnail avatars there too.

Settings that actually reach 10 KB

Scan or photograph the signature on white paper, crop hard to the ink, and let the tool output JPG at roughly 140×60 px. Ink on white has very little colour information, so quality can drop a long way before the strokes visibly break up — a signature at 10 KB usually still looks clean at full zoom.

The mistake that gets uploads rejected

People try to squeeze a full face photo into 10 KB. At passport dimensions that leaves under 0.1 bits per pixel and the face turns into blocks. If the form wants a photo and a signature, they are two separate fields with two different limits — check before compressing.
