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 10 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 10 KB

A 10 KB JPEG is a small picture, and how many pixels it can hold varies a lot with the content. Smooth areas such as plain walls and studio backgrounds compress very well; textured areas such as hair, foliage and fabric patterns do not. This is why two photos of the same dimensions can end up with very different quality at the same 10 KB. Reducing JPEG quality shrinks the file quickly at first, but below a certain point blocky artefacts appear around edges, and that is when reducing dimensions gives a cleaner result. The tool tries both in order and keeps the largest result that fits under your limit, so you keep as much quality as the budget allows.

Around 10 KB suits small passport-style photos, signature scans and form fields with tight attachment limits. Simple images with flat backgrounds reach it most easily. 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

Keep the output as JPEG, as this page only accepts JPEG files. Start with the default 10 KB target and look at the preview; if faces or text look too soft, try 15 KB or 20 KB. Photos already cropped to the subject compress noticeably better than full-frame originals.

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

Practical uses

Signature or thumbprint fields with a small attachment limit
Small passport-style photo slots in older application portals
Embedding small previews where load speed matters

Tips for a smaller file

Crop out empty background before compressing.
Use a well-lit original; noise from dark photos wastes bytes.
Avoid re-compressing a file that has already been compressed many times.
Compare the preview at actual size, not zoomed in.

Frequently asked questions

How small will my JPEG look at 10 KB?

It depends on how detailed the photo is, because the tool shrinks the picture only as much as needed to fit. The exact dimensions are shown with the result.

Does this reduce quality or dimensions first?

Quality is lowered first. If the file is still above 10 KB at the lowest reasonable quality, the dimensions are reduced step by step.

Why is my result larger than 10 KB?

Very detailed images may not reach the target within the tool's attempt limit. Try a slightly higher target or crop the photo first, then run it again.

Can I use a PNG here?

This page accepts JPEG files only. For PNG or WebP files, use one of the general image size pages such as the 15 KB or 20 KB compressor.
