Step 1: Check the size and format
The tool above is preselected to 25 KB. Choose one JPEG, PNG or WebP image from your device. If a service specifies JPG or another supported type, use the Output format control to match it.

Instructions for this target
How to compress an image below 25 KB
A simple logo stamp or black-and-white initial may fit a 25 KB budget in a tightly limited form. The budget here is illustrative, not a named site's requirement.
Step 2: Adjust settings for 25 KB
Reduce unnecessary blank margins in a suitable editor before uploading. Try PNG for crisp outlines; do not compress a full document scan so far that printed information disappears.
If you enter a width or height, use Resize and compress and keep Keep aspect ratio checked to avoid stretching. Resize only does not enforce a file-size limit.
Step 3: Verify the download
Select the compress button, inspect the before-and-after previews and check the output size and dimensions. Download only after the size verifies below 25 KB and the image still looks suitable.
A file-size pass does not mean it meets every third-party image requirement.
About this example
The use case above illustrates what someone might do with a 25 KB budget. It is not a claim that any named organisation requires this exact limit. Check your receiving service's published maximum, accepted format and required dimensions.

Other useful target sizes
Very small limits can require stronger compression or smaller dimensions, especially for detailed photos. Start here for strict forms, ID-style uploads and portals with tight file-size checks.
