Frequently Asked Questions
Which formats can I convert between? expand_more
PNG, JPEG, and WebP in any direction. The input format is detected automatically; you pick the output format.
What happens to transparent PNGs? expand_more
When converting to JPEG (which has no alpha channel) or to WebP with quality under 100, transparency is flattened onto the background color you choose.
When should I use WebP? expand_more
WebP produces smaller files than JPEG and PNG at similar quality and is supported by all modern browsers. Use it for web images wherever possible.
Need to resize as well? expand_more
Use the [Image Resizer](/tools/image-resizer/) to change dimensions, then come back here for format conversion.
Is my image uploaded? expand_more
No. All conversion happens locally in your browser.
