PNG vs JPEG vs WebP
Choose a format by transparency, detail and size.
What matters
PNG preserves sharp edges and transparency. JPEG is efficient for photographs but has no alpha channel. WebP often balances size and visual quality. The best choice depends on content, browser targets and editing needs.
A safe workflow
- Keep the source unchanged.
- Test on a representative copy.
- Review the output for meaning, not only file size or a green status.
- Record the settings that worked.
Common mistake
Automation can make a wrong assumption repeat faster. Confirm encoding, units, schema meaning or visual quality before applying a result broadly.
