Choosing a format for converted images

This converter uses the browser canvas to decode an image and encode it as JPEG, PNG, or WebP. A format change can alter compression, transparency, metadata, and file size, so the best choice depends on where the output will be used.

Batch conversion is convenient for a group of assets, but the browser still has to decode every image into memory. Converting a smaller batch is safer on devices with limited memory.

Use PNG when transparency or crisp flat graphics are important.
Use JPEG for broad compatibility and photographic images.
Use WebP when the target browser or platform supports it and smaller web files are useful.

Does this support HEIC to JPG conversion?: HEIC (iPhone photo format) is not currently supported as input because browsers do not natively decode HEIC files.
