2. Choose the target format (PNG, JPG, or WebP).
3. Adjust the quality slider for JPG or WebP output.
4. Click "Convert" to process the image.
5. Preview the result and click "Download" to save.

What is Image Format Conversion?

Image format conversion changes an image from one file format to another while preserving its visual content. Different formats offer different trade-offs between file size, quality, and feature support. PNG uses lossless compression and supports transparency, making it ideal for screenshots, logos, and graphics with sharp edges. JPG uses lossy compression optimized for photographs and continuous-tone images. WebP, developed by Google, provides superior compression for both use cases and is supported by all modern browsers.

How the Conversion Works

This tool uses the browser's Canvas API to decode the input image, draw it onto an invisible canvas element, and re-encode it in the target format. For JPG and WebP output, a quality slider controls the compression level (lower quality means smaller files but more visible artifacts). PNG output is always lossless, so there is no quality setting. The Canvas API handles color space conversion and pixel format changes automatically. All processing runs in your browser, so your images never leave your device.

Common Use Cases

• Converting PNG screenshots to JPG for smaller email attachments
• Switching to WebP for faster web page loading times
• Converting JPG images to PNG when transparency is needed
• Preparing images for platforms with specific format requirements
• Batch converting images for consistent format across a project

Choosing the Right Format

Use JPG for photographs, product images, and any image with smooth color gradients. JPG achieves excellent compression ratios but struggles with sharp text and edges, which can appear fuzzy. Use PNG for screenshots, diagrams, icons, and any image requiring transparency. PNG files are larger but preserve every pixel perfectly. Use WebP when you want the best of both worlds: it handles photographs and graphics well, produces files 25 to 35 percent smaller than JPG at equivalent quality, and supports both transparency and animation. Unless you need to support Internet Explorer or very old browsers, WebP is generally the best choice for web delivery.

For reducing file size without changing format, try the Image Compressor. To change image dimensions, use the Image Resizer. For vector-to-raster conversion, see SVG to PNG.
