Choose the output format by destination
WebP is a strong default for website images because it usually keeps quality high at a smaller file size.
Practical image guidance
Resize for the place the image will be used
A 1600 pixel wide export is enough for many full-width web layouts, while square profile photos often need exact dimensions such as 512 by 512.
Balance quality, file size, and compatibility
Lower quality settings can shrink photos quickly, but logos, text, and interface screenshots often need PNG to keep edges crisp.
Specific advice for JPG to AVIF
Budget for encoding time
AVIF can take longer to encode than JPEG or WebP, especially for large images.
Do not compare quality numbers across formats
Quality 82 in AVIF is not a promise of the same appearance or file size as quality 82 in JPEG.
Check the receiving application
Some image editors and upload forms do not accept AVIF even when a browser can display it.
How it works
Choose a JPEG photo.
Select your dimensions and AVIF quality.
Convert and check the result in its intended destination.
