How It Works
Upload an image, select the output format (PNG, JPEG, WebP, BMP), and download the converted file. All processing happens locally — no upload to servers.
**Image Format Converter — Convert Between Any Image Format**
Different image formats suit different purposes. Converting between them is a common need for web developers, designers, and content creators. Our Image Format Converter handles all common web image formats, with client-side processing for complete privacy.
**Image Format Comparison**
**JPEG/JPG**
- Lossy compression, no transparency
- Best for: Photographs, complex images with gradients
- Avoid for: Screenshots, text, logos (artefacts at high compression)
- Typical size: 200KB–2MB for a 12MP photo
**PNG**
- Lossless compression, supports transparency
- Best for: Screenshots, logos, graphics with text, transparent backgrounds
- Avoid for: Photographs (larger file size than JPEG)
- Typical size: 500KB–5MB for a 12MP photo
**WebP**
- Modern format by Google, lossy or lossless
- Best for: Web images where file size is important
- 25–34% smaller than JPEG at equivalent quality
- Supported by all modern browsers (Chrome, Firefox, Safari 14+)
**GIF**
- Lossless but limited to 256 colours
- Best for: Animations, simple graphics
- Avoid for: Photographs (too few colours)
**BMP**
- Uncompressed, large files
- Best for: Legacy Windows applications requiring uncompressed images
- Avoid for: Web use (extremely large files)
**When to Convert**
*JPEG → WebP:* Reduce file size 25–35% for web performance
*PNG → JPEG:* When transparency is not needed and smaller file size matters
*GIF → WebP:* For animated images with better compression
*Any → PNG:* When you need transparency or lossless quality
**Privacy Note**
All conversion uses the HTML5 Canvas API in your browser. No image data is transmitted.
