JPG is the most widely accepted image format for forms, applications and email, and a 100KB cap is one of the most common limits you will meet. This tool is locked to JPG output, so every result is guaranteed to be a universally compatible JPG file at or below 100KB.
The tool searches for the highest quality that still fits the 100KB ceiling. Because JPG compresses photos efficiently, most images reach 100KB with only minor visible loss. If your JPG is very large (for example a full-resolution phone photo), the quality will need to drop further — in that case, resize the image first for a cleaner result.
JPG is the safest format for 100KB form limits because every system accepts it. The tool keeps the best quality that fits.

Frequently asked questions
How do I compress a JPG to under 100KB?
Drop your JPG into the tool above. It automatically lowers the quality until the file is 100KB or less, then shows the final size. Output is always JPG.
What if my JPG is still over 100KB?
The image probably has too many pixels. Resize it to a smaller width first, then compress again. Very large photos may need to be around 1000 pixels wide to fit 100KB cleanly.
Does JPG compression to 100KB look bad?
For normal photos the loss is usually hard to notice. The tool keeps the highest quality that fits the limit, so the result is as clean as possible at 100KB.
Is the JPG to 100KB compressor free and private?
Yes. Everything runs entirely in your browser, so your image is never uploaded. It is free with no sign-up, no watermark and no limits.
