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.

Frequently Asked Questions

Yes, for modern websites. WebP provides 25–34% smaller file sizes than JPEG at equivalent quality. All modern browsers support it. Serve JPEG as a fallback for older browsers.
Yes. JPEG does not support transparency. Transparent areas are filled with white (or a colour you specify) during conversion.
JPEG is already lossy, so previous compression artefacts are preserved. Converting JPEG to PNG won't recover lost quality, but future saves as PNG won't add further loss.
SVG is ideal for logos (scalable, smallest file size). If SVG is not available, PNG with transparency is the best raster option.
The tool handles images up to ~10MB. Very large images may be slow to process in the browser.
