Every time you save or export an image, you are making a choice that affects file size, quality, and compatibility. Most people just use whatever format their camera or phone saves in — but that is not always the best option. Let us break down the three most important formats.
JPG / JPEG
Best for photographs and complex images. Small files, universal support, no transparency.
PNG
Best for graphics, logos, screenshots. Lossless quality, supports transparency. Larger files.
WebP
Best for websites. Smaller than JPG and PNG. Supports transparency. Modern browsers only.
JPG — The Standard for Photos
JPEG (Joint Photographic Experts Group) has been the go-to format for photographs since the 1990s. It uses lossy compression which means it permanently removes some image data to shrink the file size.
Use JPG when:
- Sharing or uploading photographs
- File size matters and you do not need transparency
- Compatibility with older devices or software is required
- Publishing blog images, product photos, or backgrounds
Avoid JPG when: You need a transparent background, or your image contains sharp-edged text, logos, or line art — JPEG compression creates visible "artifacts" around these.
PNG — Perfect Quality, Larger Files
PNG (Portable Network Graphics) uses lossless compression. Every pixel is saved exactly as-is, which means the output is identical to the original no matter how many times you save it.
Use PNG when:
- Your image needs a transparent background (logos, icons, stickers)
- You are saving screenshots with text
- You are working with graphics, illustrations, or UI elements
- You need to edit and re-save the image multiple times
Avoid PNG when: You are saving photographs. A PNG photo can be 3–5 times larger than the same image in JPG with no visual benefit.
WebP — The Modern Winner for Websites
WebP was created by Google specifically for the web. It uses advanced compression that beats both JPG and PNG on file size while maintaining excellent quality.
- 25–35% smaller than JPG at equivalent quality
- Up to 50% smaller than PNG for lossless images
- Supports full transparency like PNG
- Supported by Chrome, Firefox, Safari 14+, Edge — all modern browsers
✅ Recommendation: If you are building a website today, use WebP for all your images. Convert your existing JPGs and PNGs using our free WebP Converter.
