02 / DETAILS
About this conversion
Apply one output format and quality setting to many images at once, then download a ZIP with each converted file.
Batch conversion uses the same setting for each selected image. If a photo has transparency and the output is JPEG, transparent areas are filled with the chosen background color.
Limits to know
Each input is limited to 40 MiB and 16 megapixels so the browser has a safer memory budget. Very large dimensions can still exceed the memory available on a phone.
Processing runs in this browser. Originals are not overwritten, and the output size is measured in bytes before download. Keep a backup of important files.
03 / FAQ
Questions people ask
How do I receive several converted files?
They are packaged into one ZIP archive for a single download.
Are file names kept?
The output uses the source name with a new extension; duplicate names receive a safe numbered suffix.
