About this tool
Phone photos are large because they are large in pixels and lightly compressed. This page scales the long edge and writes a new JPEG unless you picked another format. The original on disk stays until you overwrite it yourself. Location data is not copied into the download. A photo that is already a few hundred kilobytes may not shrink, and it should not be damaged to pretend.
Reduce photo size is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.
- No upload: the pixels never go to an image host.
- Speed: processing happens instantly on your device with no upload or download delays.
- Quality: you can check your file before saving, and the original remains unchanged.
