Image Format Converter

Modern web development demands multiple image formats. PNG for screenshots and graphics, JPG for photos, WebP for web performance, AVIF for maximum compression. Managing these conversions shouldn't require Photoshop, ImageMagick, or uploading files to a third-party service.

Format guide

- **JPEG/JPG**: Lossy compression. Best for photographs. Not suitable for graphics with sharp edges or text (produces blocking artifacts). Does not support transparency. - **PNG**: Lossless compression. Best for screenshots, UI graphics, and images requiring transparency. Larger files than JPEG for photos. - **WebP**: Supports both lossy and lossless compression. Smaller than JPG/PNG for equivalent quality. Supported in all modern browsers (Chrome, Firefox, Safari 14+, Edge). - **AVIF**: Based on AV1 video codec. Best compression for web use. Supported in Chrome 85+, Firefox 93+, Safari 16.4+. Still not universally supported — test before deploying.

Conversion happens in the browser

This tool uses the HTML Canvas API to draw your image and export it in the target format. The Canvas API is built into every browser and runs natively without any server involvement. Your files are never transmitted.

Transparency handling

When converting PNG (with alpha channel) to JPG (no alpha), transparent areas must be filled. White is the default fill — you can customize this in settings. For WebP and AVIF output, transparency is preserved.
