Local image workflow
The image is decoded and re-exported by the browser. This keeps routine compression fast and avoids unnecessary uploads.
Quality and size
Lower quality usually means a smaller file. Reducing dimensions can also save more bytes than quality changes alone.
When to use WebP
WebP is often a good choice for modern websites, but JPG or PNG may still be required by older systems.
Common use cases
- Reduce images before publishing on a website.
- Prepare smaller files for forms and email.
- Compress screenshots or photos before sharing.
Limitations
- PNG images with transparency may not shrink as much.
- Very large images can use significant memory on mobile devices.
- Compression can change visual quality, so inspect the preview.
