How to use this tool

Choose a JPEG file, or drag it onto the drop area. Only .jpg and .jpeg files are accepted on this page.
Check the target size (currently 25 KB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool lowers the quality first, then reduces the dimensions step by step if the file is still too large.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you compress JPEG to 25 KB

At 25 KB a standard portrait can usually remain clear and recognisable at modest dimensions. It is a middle step between the very small 10 to 20 KB tier, where quality suffers, and the 40 to 50 KB tier, where faces look comfortable. Because JPEG quality has a steep early curve, going from a camera original down to 25 KB removes most of the file in the first few steps, and the last few kilobytes are the hard part. If the picture is still above the limit after reducing quality, the tool scales down in small steps rather than one big jump. Portraits against plain backgrounds hit 25 KB with the least visible damage; patterned clothing and busy scenery take the most.

A 25 KB budget keeps a recognisable portrait at modest dimensions. It is a typical limit for application-form photographs. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

Only JPEG files are accepted here. Keep the 25 KB default or adjust it using the editable target field. For passport-style pictures, crop to head and shoulders before compressing so the available bytes describe the face rather than the surroundings.

Accepted input: JPEG (.jpg, .jpeg). Output is always JPEG, and transparent areas, if any, are filled with white.

Practical uses

Online application and job-portal photo uploads
ID card and membership photo submissions
Reducing a headshot before attaching it to a lightweight form

Tips for a smaller file

Crop to head and shoulders before you compress.
Use even lighting to avoid noisy shadow areas.
Start from the original photo, not a screenshot of it.
If the form measures 25 KB strictly, aim a little lower for safety.

Frequently asked questions

Is 25 KB enough for a clear passport-style photo?

It is usually enough for a recognisable portrait at modest dimensions. Fine details and small text will look softer than in the original.

Why do I need a JPEG for this page?

This page is built for JPEG files, which are the most common format for photo upload limits. For PNG or WebP, try the general image size pages.

Can I get below 25 KB?

You can edit the target to a lower value, but the smaller you go, the more quality and size are lost. Check the preview each time.
