How to Convert Between PNG, JPG, WebP, and AVIF
Pick the right image format for your use case. Convert between PNG, JPG, WebP, and AVIF in your browser — no upload, no quality loss when it matters.
Picking the Right Format
Each image format has a sweet spot:
| Format | Strengths | Use it for |
|---|---|---|
| JPG | Tiny files, universal support | Photos for email or print |
| PNG | Lossless, transparency | Logos, screenshots, UI assets |
| WebP | 30% smaller than JPG, transparency | Web images |
| AVIF | Best compression, modern | Cutting-edge web |
How to Convert
- Open the Image Converter
- Drop your image
- Pick the target format — JPG, PNG, or WebP
- Click Convert
- Download
Things to Know
- JPG to PNG doesn't make the JPG lossless. Once compression artifacts are baked in, they stay.
- PNG to JPG discards transparency. ImageSpark fills the background with white.
- Anything to WebP typically saves 25–35% compared to JPG with no visible quality difference.
Bulk Conversion
Pro users can drop in multiple files and convert them all at once. Free users can convert up to 5 images per day.
Privacy First
Like every other tool on ImageSpark, conversion happens entirely in your browser. We never see your images.
