Question 1

Are my images uploaded to a server?

Accepted Answer

No. Conversion happens entirely in your browser using the Canvas API — your files never leave your device.

Question 2

What formats are supported?

Accepted Answer

You can upload JPG, PNG, WebP, GIF, BMP, AVIF, or SVG images, and convert them to JPG, PNG, WebP, BMP, or ICO (favicon format).

Question 3

Can I convert multiple images at once?

Accepted Answer

Yes — drop or select several files and they'll all convert to your chosen format together.

Question 4

Why does JPEG have a quality slider but PNG doesn't?

Accepted Answer

PNG is lossless, so there's no quality trade-off to make. JPEG and WebP use lossy compression, so lowering quality reduces file size at the cost of some detail.

Question 5

Can I use this to make a favicon?

Accepted Answer

Yes — convert any image to ICO and it's ready to use as favicon.ico. Images larger than 256×256 are automatically scaled down to fit.
