About this tool
What this tool does
Compress an image when a website or form rejects a file because it is too large. The tool reduces file weight while keeping the dimensions unchanged unless you resize separately.
How to read the result
The result shows original and compressed size, so you can judge the saving before download. Stronger compression usually creates a smaller file but may soften fine details.
Practical guidance
Use moderate compression first and inspect text, edges and faces in the preview. For a strict KB limit, reducing pixel dimensions before another compression pass often gives a cleaner result.

FAQ
Is this tool free?
Yes. The tool is free to use and does not require login.
Can I use sensitive data?
Avoid entering or uploading confidential data unless you have verified how that type of file or data is processed.
Does image compression reduce quality?
It can, especially with strong compression. Always review the result before publishing.
Is this useful for product photos?
Yes. Product photos are a common use case before uploading to a shop or CMS.
Why did my image shrink only slightly?
It was probably already optimized or contains content that is hard to compress further.
Can I compress an image to 100KB?
Yes. Enter 100 in the target size field. The tool will try to reduce quality and dimensions until the image fits below the limit.
Can I use this for online forms?
Yes. Enter the file size limit from the form, for example 100KB or 500KB, and the tool will try to create a smaller image.
