Quick Answer
The best image format depends on the job. Photos, transparent graphics, icons, screenshots, printable images, and animated files each have different tradeoffs.
Step-by-Step
- Use JPG or WebP for photos when small file size matters and transparency is not needed.
- Use PNG when you need transparency or crisp screenshots, and SVG for scalable vector graphics.
- Use AVIF or WebP for modern web optimization after checking browser and workflow support.
- Check dimensions, file size, metadata, and visual quality before uploading the final file.
Recommended Workflow
Open the most relevant calculator or utility first, enter a realistic starting point, then use the supporting tools to check assumptions, clean inputs, or prepare the final output.
