How it works
Converts an image from one format to another among PNG, JPG, WebP, AVIF, GIF, BMP and ICO. It is useful for adapting a photo or graphic to the format your website, editor or workflow needs without installing programs.
You choose the output format and, for those that support lossy compression (JPG, WebP, AVIF), adjust the quality to balance sharpness and weight. The conversion is done by re-encoding the image, not just changing the file's extension.
All processing happens in your browser: the image is never uploaded to a server. Modern formats like WebP and AVIF achieve lighter files than JPG or PNG at similar quality.
Use cases
- Turn a heavy PNG into WebP or AVIF to speed up a website's loading.
- Convert a WebP or AVIF to JPG or PNG to open it in programs that don't support it.
- Transform an image to ICO to use it as an application icon or favicon.
- Unify the format of a batch of screenshots before uploading or sharing them.
Frequently asked questions
What is the difference between WebP and AVIF?
Both are modern formats that compress better than JPG and PNG. AVIF usually achieves smaller files at the same quality, while WebP has somewhat wider support in older browsers and tools.
Does converting to JPG preserve transparency?
No. JPG does not support transparency, so transparent areas are filled with a background color. If you need to keep transparency, choose PNG, WebP or AVIF.
Is quality lost when converting?
When moving to a lossy format (JPG, WebP, AVIF) there is a recompression that can reduce quality, controllable with the quality setting. Lossless formats like PNG preserve every pixel.
Are my images uploaded to a server?
No. The conversion happens entirely in your browser; the image never leaves your device.
