Plenty of upload forms stop at 100 KB. The CTET information bulletin asks for a scanned photograph between 10 and 100 KB, and the University of Kent asks for a student card photo between 1 and 100 KB (both checked 24 Oct 2026). Open the file and the card is already set to 100 KB and JPG: it keeps the highest quality between 92 and 50 that fits, and only then scales the pixels down. The size, quality and pixels show before you download.

1. Click Choose an image, or drop the photo or scan on the page. The result card opens with Size limit at 100 KB and Format set to JPG.
2. Read the line under the chips. For the sample portrait it reads 3.0 MB → 98.4 KB · JPG · quality 55 · 1114 × 1486: even quality 50 didn't fit at full size, so the pixels were scaled down too. If the form names pixels, click Resize under Next and type them first.
3. Click Download JPG. If the form also sets a minimum, such as 10 KB, check the size against it as well before you upload.

Which forms ask for 100 KB?

Exam boards, colleges and some university services. The CTET bulletin from India's Central Board of Secondary Education asks for a photograph of 10 to 100 KB and a signature of 3 to 30 KB; the University of Kent asks for a JPG student card photo of 1 to 100 KB, preferably 286 × 388 pixels and no bigger than 500 × 500 (both checked 24 Oct 2026). Numbers change between notices, so read the one for your round.

Why won't my PNG go under 100 KB?

PNG is lossless, so the card doesn't squeeze it to a limit. Leave Format on JPG and the card finds a quality that fits.

Will the picture lose pixels?

A small photo often doesn't. The card lowers the quality to 50 first and only then scales, so a photo of about a megapixel usually keeps its pixels at 100 KB. A 12-megapixel phone photo does: the sample portrait, 3024 × 4032 and 3.0 MB, comes out at 1114 × 1486.

The form also names pixels, such as 286 × 388. What do I do?

Set the pixels first: click Resize under Next and type them, then check that the size line still reads under 100 KB. At that size most photos fit at a high quality. The CTET bulletin gives centimetres instead, 3.5 × 4.5 cm: click Crop under Next and crop to that shape first.

What are the limits?

It opens JPG, PNG, WEBP, HEIC, GIF and BMP and saves a JPG at the highest quality between 50 and 92 that fits, so the file lands under 100 KB rather than exactly on it. The card counts 1 KB as 1,000 bytes, so the file also passes forms that count 1,024. One image at a time; everything runs in your browser and nothing is uploaded.
