How to use, privacy & sources

How to use & assumptions

01 / Choose images or a folder. Set format, dimensions and target size; confirm whether animation may become a still image.

02 / Review actual bytes and format for every image. Reduce dimensions and retry if the target was missed; download a ZIP.
