Can I resize a PNG image to 100kb?

Yes, you can upload PNG images. If the file size is very large, the tool will compress and convert it to JPEG to meet the 100kb target size while maintaining readability.

Is my uploaded image secure?

Yes, all processing is done locally in your browser. Your images are never uploaded or saved to our servers, ensuring complete privacy.

How do I ensure my photo is exactly under 100kb?

Our tool automatically adjusts the quality parameters to bring the file size as close as possible to (and strictly under) 100kb.
