Free online image tool
Prepare JPEG photographs for modern websites. WebP is selected for you; resize a large camera image to its display size before comparing file sizes.
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.
For a 600-pixel-wide content area, a 1200-pixel export can serve a high-density display without sending a full camera original. Enter a width and leave height blank to preserve proportions.
An already optimized JPEG can occasionally be smaller than a WebP export. Compare the source and result sizes shown by the tool, and lower quality gradually if you still need a smaller image.
Modern browsers commonly display WebP, but a print vendor or upload portal may still request JPEG. Keep the camera original so you can produce both formats without converting an already compressed export again.
