Compress Image to 150KB: is this the right limit?
This preset starts the image compressor at 150KB. 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 web or application image that needs more detail than a tiny thumbnail while staying under 150KB.
Practical advice for 150KB
Keep the crop focused and use the preview to balance sharpness against size. If the destination accepts a larger file, avoid shrinking below the pixel dimensions it requests.
A 150KB ceiling can retain more visual information than very small targets, but detailed or high-resolution sources may still need resizing or quality reduction.
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 150KB 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.
