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 WebP
Match the rendered image size
For a 600-pixel-wide content area, a 1200-pixel export can serve a high-density display without sending a full camera original.
Compare bytes rather than assuming savings
An already optimized JPEG can occasionally be smaller than a WebP export.
Keep a JPEG copy for other destinations
Modern browsers commonly display WebP, but a print vendor or upload portal may still request JPEG.
How it works
Choose a JPG or JPEG photo.
Use quality 82 as a starting point and optionally resize.
Convert and compare the size and preview before downloading.
