Frequently Asked Questions
Are my images uploaded?
No. Conversion runs locally in your browser and your images never leave your device.
Which output formats are supported?
You can export JPG, PNG, WebP and AVIF, and copy the Base64 data URL of your image.
Why can’t I export AVIF?
AVIF export depends on browser support. Chrome or Edge 100+ is recommended.
What happens to transparency when converting to JPG?
JPG has no alpha channel, so transparent areas are filled with white. Export PNG or WebP to keep transparency.
