How we process your filesMake a small upload without losing the important parts
A 100 KB limit leaves little room for a large camera photo. This preset starts with that target, but the right result still depends on the image and the receiving form. Check the form itself rather than assuming 100 KB is a standard requirement.
Keep only the pixels you need
Check the required dimensions before compressing. If a large photo only needs to appear as a small picture, resizing first may preserve useful detail better than aggressive compression alone.
Try the preset on your image
Process the file with the 100 KB target. Inspect faces and small text closely; fine details can be hard to retain within a tight limit.
Confirm both size and legibility
Check the final size and any target warning. If the limit is not met, use smaller permitted dimensions or another accepted format. Keep the original for a less restricted use.
Frequently asked questions about Compress Images to 100 KB
Learn what the settings do and what to check in the finished image.
Can every image reach 100 KB?
No. The image content, dimensions, and format affect the smallest achievable size. The results show when the limit is not met.
The limit was not reached — what should I try first?
Reduce pixel dimensions before compressing again. A large photo under a tight limit usually needs fewer pixels, not just lower quality. If you also need a specific shape, crop it first, then resize, then compress.
