How to Convert Images Online
Our free image format converter transforms images between popular formats including PNG, JPG, WebP, BMP, and GIF — all within your browser without uploading files to any server.
Supported Image Formats
- **PNG** — Lossless, supports transparency. Best for graphics and logos.
- **JPG/JPEG** — Lossy compression, smaller files. Ideal for photographs.
- **WebP** — Modern format by Google. 25-35% smaller than JPG/PNG at equivalent quality.
- **BMP** — Uncompressed. Full quality but large file sizes.
- **GIF** — Supports animation. Limited to 256 colors.
Common Conversion Scenarios
**PNG to JPG:** Reduce file size for photographs. Transparency replaced with white background.
**JPG to PNG:** Add transparency support or eliminate compression artifacts.
**Any to WebP:** Modernize images for web use. Best compression-to-quality ratio.
Why Client-Side Conversion Matters
Traditional online converters require uploading files to their servers, raising privacy concerns. Our tool uses the HTML5 Canvas API to process images entirely on your device. Your images never leave your browser.
FAQ
**Will converting PNG to JPG reduce quality?** Yes, JPG uses lossy compression. For photographs the difference is usually imperceptible.
**Best format for web?** WebP provides the best compression. Use JPG/WebP for photos, PNG/WebP for transparency.
