Image Format Guide: JPEG vs PNG vs WebP vs HEIC
6 min read
Choosing the right image format can reduce file sizes by 50% or more without any quality loss. But with formats like WebP, AVIF, and HEIC entering the mainstream, the decision has become more complex. This guide explains when to use each format.
JPEG — Best for Photos
Pros: Universal support, small file sizes, excellent for photos and gradients.
Cons: No transparency, lossy compression only, degrades with repeated editing.
Best for: Photographs, web images, social media, email attachments.
Avoid for: Screenshots with text, logos, graphics needing transparency.
PNG — Best for Graphics & Transparency
Pros: Supports transparency, lossless compression, perfect for text/graphics.
Cons: Larger file sizes for photos, no animation (use APNG for that).
Best for: Logos, icons, screenshots, images with text, transparent backgrounds.
Avoid for: Large photographs (use JPEG or WebP instead).
WebP — Best Overall for Web
Pros: 25-35% smaller than JPEG at same quality, supports transparency and animation.
Cons: Slightly less universal than JPEG/PNG (but 97%+ browser support in 2026).
Best for: All web images — both photos and graphics. The recommended default for modern websites.
Avoid for: Print materials, archival storage (use TIFF or PNG).
HEIC/HEIF — Best for Apple Devices
Pros: 50% smaller than JPEG at same quality, supports depth data and live photos.
Cons: Limited browser support, not web-friendly, requires conversion for sharing.
Best for: iPhone/iPad photo storage, Apple ecosystem.
Convert to: JPEG or WebP before uploading to web or sharing online.
| Format | Transparency | Animation | Compression | File Size | Browser Support |
|---|---|---|---|---|---|
| JPEG | No | No | Lossy | Small | 100% |
| PNG | Yes | No | Lossless | Large | 100% |
| WebP | Yes | Yes | Both | Smallest | 97%+ |
| HEIC | Yes | No | Both | Small | Limited |
Our Recommendation
For websites: Use WebP as your default format. It offers the best compression with full feature support.
For transparency: Use WebP (modern) or PNG (maximum compatibility).
For email/sharing: Use JPEG — it works everywhere without issues.
For archival: Use PNG or TIFF for lossless, long-term storage.
