Try an AVIF version of a JPEG photo for a compatible website. Compare the result with your original rather than expecting a fixed compression percentage.
WebP is a strong default for website images because it usually keeps quality high at a smaller file size. JPEG is practical for photo uploads and forms, PNG is better for screenshots or transparent artwork, and AVIF can be useful when the destination supports newer formats.
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. Keeping enlargement disabled prevents small originals from becoming soft or stretched.
Lower quality settings can shrink photos quickly, but logos, text, and interface screenshots often need PNG to keep edges crisp. The best result depends on whether the image is headed to a website, email, form upload, product listing, or profile.
AVIF can take longer to encode than JPEG or WebP, especially for large images. Resize oversized source photos first and let the current conversion finish before starting another.
Quality 82 in AVIF is not a promise of the same appearance or file size as quality 82 in JPEG. Compare gradients, fine textures, and the actual result size at the dimensions you plan to publish.
Some image editors and upload forms do not accept AVIF even when a browser can display it. Keep a JPEG or WebP export available for destinations that reject the new file.
