Compress an Image Below 100 KB
For an upload form with a 100 KB maximum, start with a JPG or WebP export. Automatic resizing can reduce dimensions when quality changes alone are not enough. Check whether your form also requires specific pixel dimensions.

Check the whole requirement.
A file-size limit and an image-dimension requirement are different things. This tool reports both.
Your quick checklist
- Confirm the allowed file formats and maximum byte size.
- Choose fixed dimensions only if the destination needs them.
- Process your files and check the Ready or Over limit label.
- Download and inspect the image before uploading.
Compression is lossy for JPG and WebP. Keep your original if you may need higher quality later.
