How to get an image under 100 KB
Choose your image, keep the 100 KB limit, then select Prepare Image. Add width and height if your upload form asks for them. The download is checked against 100,000 bytes, a conservative decimal KB limit.
Compress Image to 100KB
Get a checked image at or below 100,000 bytes. Add the pixels your form requires, then preview and download.

A useful size for application forms
A 100 KB limit is often easier to meet when a photo is resized to the dimensions the form actually requires. For a square photo, choose Crop and enter equal width and height. Check that the centred crop keeps your face in frame.
What happens to image quality?
For ordinary-size JPG and WebP output, UploadMint tests several quality levels and keeps the highest tested quality that fits. Full-resolution large HEIC-to-JPG output keeps your selected quality and may stop if it cannot meet the cap. PNG is lossless, so a smaller PNG may require fewer pixels.
What if 100 KB is too small?
If you allow smaller dimensions, UploadMint searches for a usable resolution while respecting its quality and resolution safeguards. If dimensions must stay exact, it explains when the limit cannot be reached. Increase the limit or choose another format.
Your image stays with you
UploadMint processes supported images in your browser. Your image is not uploaded to a processing server, and no account is needed. Closing the page clears the working image.
Good to know
Will the download be exactly 100KB?
The limit is a maximum of 100,000 bytes, not a target to pad the file to. A smaller result is valid for an at-or-below limit. Check whether your form also sets a minimum file size or specific dimensions.
Can I keep exact dimensions and stay under 100KB?
Enter the required width and height, choose Crop for an exact shape, and leave permission to reduce dimensions off. If the file cannot fit at a usable quality, the tool explains the limit instead of changing those dimensions. A centred crop may remove content near the edges.
