How The Formats Work
JPG uses lossy compression and is usually best for photos. PNG preserves transparency and crisp edges but can create large files for photographs. WebP supports strong compression and transparency, making it a strong modern web format when browser and platform support are acceptable.
Benefits of Choosing Correctly
The right format prevents blurry graphics, unnecessary file size, broken transparency, and rejected uploads. It also makes later compression more predictable because each format responds differently to quality settings and image content.
Use Cases
- Use JPG for camera photos and realistic product images.
- Use PNG for logos, icons, and transparent artwork.
- Use WebP for modern web pages that need small, high-quality files.
- Use PNG or WebP when transparency matters.
- Avoid JPG for images that require a transparent background.
Examples
A food photo can be JPG or WebP. A transparent logo should be PNG or WebP. A screenshot with text may look clean as PNG, while WebP can reduce size for web publishing. A marketplace upload may require JPG even when WebP would be smaller.
Step-by-Step Format Choice
- Check whether the image needs transparency.
- Decide whether the destination accepts WebP.
- Use JPG or WebP for photos.
- Use PNG or WebP for sharp graphics.
- Compress and inspect the result before publishing.
