Free online image tool
Convert, resize, and compress your images. Choose a file, pick a format, and download the result. No account needed.
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.
