How to compress a photo for an upload limit

Choose your image, wait for the output size, and download the new JPEG. Keep your original, then open the smaller copy to check that faces, text, and fine details are still clear before uploading.

Does 100 KB mean 100,000 bytes?

This tool uses a limit of 100,000 bytes. If the upload form also specifies pixel dimensions or requires PNG, check those requirements separately. JPEG does not support transparency, so transparent areas are filled with white.
