Choose HEIC → WEBP when you need a smaller web image.
HEIC is decoded in the browser before the new WEBP file is encoded. Pixel dimensions stay unchanged by default, but the new encoding can change file size and pixel values. WebP can reduce web image size and keep alpha when supported by the decoded input; quality affects the result.
Pixel dimensions stay the same by default. Metadata is not guaranteed to carry over.
The image is newly encoded with target quality controls. Quality, file size and pixel values can change while dimensions stay the same. WebP can reduce web image size and keep alpha when supported by the decoded input; quality affects the result.
Best fit: WebP can reduce web image size and keep alpha when supported by the decoded input; quality affects the result.
Keep the source until the result opens correctly. A damaged file, unsupported encoding or decoder failure can prevent conversion.
The receiving workflow decides the choice: Use this when you need a smaller web image.
The browser decodes HEIC first. Pixel dimensions stay unchanged by default, but the new encoding can change file size and pixel values.
WEBP is useful when you need a smaller web image. WebP can reduce web image size and keep alpha when supported by the decoded input; quality affects the result.
Before replacing the source, check the downloaded file: Keep the source until the result opens correctly. A damaged file, unsupported encoding or decoder failure can prevent conversion.
