FAQ
Is this tool really free?
Yes. CompressImageTo20KB is free to use and does not require sign-up.
Which image formats are supported?
JPG, JPEG, and PNG are supported in the first version. The compressed result keeps the original format.
Will the image quality be reduced?
Yes. To reach 20KB, the service can reduce quality and automatically lower pixel dimensions.
What is the maximum file size?
The first version does not add a business file-size limit, but very large files may take longer to upload and process.
Is my image data safe?
Images are uploaded to R2 and processed for compression. Do not upload private documents unless you accept that server-side flow.
