Frequently Asked Questions

Is this different from a general image compressor? Yes — this tool only accepts JPEG input and is optimized for JPEG compression parameters, giving better results for photos than a generic tool that handles all formats equally.

Will compressing to 100KB ruin my photo? The tool maximizes quality within the 100KB constraint. For most smartphone or camera photos, the visual difference is minimal. The algorithm searches for the highest quality that still fits under 100KB.

Can I compress a PNG using this tool? This specific tool is designed for JPG/JPEG files. For PNG compression, please use our Compress PNG Under 100KB tool instead.

Is there a file size limit for the input? We recommend input files up to 50MB. The tool runs entirely in your browser, so very large files may take a few extra seconds depending on your device's processing speed.
