Questions
How many images can I convert at once?
As many as you like — it all runs on your own device, so there's no server limit. Very large batches are only bounded by your browser's memory.
Are the files uploaded?
No. Every image is converted locally in your browser and zipped on your device. Nothing is sent to a server.
Can I mix formats?
Yes. Drop a mix of HEIC, PNG, JPG, WebP and more — each is converted to your chosen output. Files already in the target format are skipped.
