Why convert image formats?
Each image format has its strengths and limitations. Converting an image from one format to another lets you optimize file size, ensure compatibility with a platform, or meet specific technical requirements (transparency, quality, maximum weight).
Image format comparison
| Format | Pros | Cons | Best for |
|---|---|---|---|
| JPEG | Very lightweight, universal | No transparency, lossy | Photos, social media |
| PNG | Lossless, transparency | Larger files | Logos, screenshots, graphics |
| WebP | Excellent size/quality ratio | Less supported outside browsers | Web, mobile apps |
| BMP | No compression, pixel-perfect | Very large files | Print, professional editing |
Most common conversions
- PNG to JPG: reduce the weight of screenshots or graphics when transparency isn't needed. Expect 50-90% size reduction.
- WebP to JPG: share a web-downloaded image in software that doesn't support WebP.
- JPG to PNG: avoid further losses during repeated edits (PNG preserves every pixel).
- Any to WebP: optimize website images. WebP provides 25-35% better compression than JPEG at equal quality.
How our converter works
Our tool uses the HTML5 Canvas API built into your browser. The image is drawn on an invisible canvas and exported in the chosen format via canvas.toBlob(). For JPEG and WebP, you can control output quality. Everything happens locally β your images never leave your device.
Practical tips
- When converting to JPEG, transparent areas are filled with white.
- Batch mode lets you compress and convert up to 10 images at once.
- After conversion, consider resizing if the image is too large for your use case.
