Cancel stops queued jobs and terminates active workers. On the main-thread fallback, an active encode must finish before cancellation is reported. Retry keeps the original file.
Files stay on your device. Downloads contain only completed outputs.
How this tool works
Choose one destination format and check transparency handling before processing mixed sources. JPEG fills transparent regions; PNG and WebP can preserve them. ZIP packages completed outputs with safe unique names and does not guarantee extra compression savings.
Choose supported files, review settings, process on your device, and inspect the output before downloading. Conversion may increase file size or change color representation. Re-encoding generally drops original metadata.
The shared queue runs at most two image jobs at once. Invalid items fail individually. HEIC and SVG use single-file tools; ZIP includes only completed outputs.
