Compress Image to 15KB: is this the right limit?
This preset starts the image compressor at 15KB. It is most useful when the website, application, or document portal accepting your image specifies that maximum. The result depends on the source image; a target is not a promise of identical quality or exact output size.
When this target makes sense
a compact upload for a simple form image or signature when the required limit is around 15KB.
Practical advice for 15KB
Crop to the required subject and avoid enlarging a small source. If a portal has a minimum pixel dimension as well as a file cap, check both requirements after compression.
A 15KB file can suit low-detail content, but it may not preserve the fine detail of a camera photo. File size alone does not confirm that an application will accept the image.
A reliable image-compression check
- Check the destination's maximum file size, accepted format, and required pixel dimensions.
- Upload up to three images (20MB maximum each), crop unused content if helpful, and keep the 15KB preset unless you need another limit.
- Compress and review the resulting image. Confirm its actual size and that important text, edges, and subject details remain clear.
- If it is still too large or no longer readable, try a more focused crop or a larger limit if the destination allows one.
Choose a different image size
Use the limit required by the receiving site. These presets change the starting target; the tool also lets you adjust it.
