Image converter questions
Which format is best for a website?
WebP is supported by all current major browsers and is usually smaller than JPG or PNG at similar quality. Use PNG only for graphics that need sharp edges or transparency.
What happens to transparency when converting to JPG?
JPG has no transparency, so transparent areas are filled with white.
Why is AVIF missing?
AVIF output is shown only if your browser can encode it. If you do not see it, use WebP, or try a recent version of Chrome or Edge.
Are my files uploaded?
No. Conversion uses your browser canvas, and the files never leave your device.
