Compress Image to 30KB: is this the right limit?
This preset starts the image compressor at 30KB. 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 application image or thumbnail when the destination permits no more than 30KB.
Practical advice for 30KB
Crop first, then review the subject and any text in the resulting preview. If your image is already below 30KB, there may be no benefit to recompressing it.
Thirty kilobytes works better for uncluttered images than for detailed scenes. Do not treat reaching the number as proof that the image meets a site's dimensions or quality rules.
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 30KB 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.
