About Image Format Conversion

Different image formats serve different purposes. JPEG is great for photographs with small file sizes. PNG preserves transparency and quality for graphics. WebP and AVIF offer the best of both worlds with smaller sizes. Our converter uses ImageMagick WASM technology to handle all these conversions right in your browser, ensuring your images stay private while giving you professional-grade results.

Frequently Asked Questions

Common questions about image format conversion

Is my data safe?

Yes! All image processing happens entirely in your browser using WebAssembly technology. Your images are never uploaded to any server, ensuring complete privacy and security.

What formats are supported?

We support over 40 image formats including PNG, JPEG, WebP, GIF, BMP, TIFF, AVIF, HEIC, HEIF, ICO, PSD, and RAW camera formats from Canon, Nikon, Sony, Fuji, and more.

Can I convert HEIC to JPEG?

Yes! HEIC (High Efficiency Image Container) files from iPhones can be easily converted to JPEG or any other format. This is one of our most popular conversions.

What's the difference between lossy and lossless formats?

Lossy formats like JPEG reduce file size by discarding some image data, which may slightly reduce quality. Lossless formats like PNG preserve all image data but result in larger files.

Why should I use WebP or AVIF?

WebP and AVIF are modern formats that offer significantly smaller file sizes than JPEG and PNG while maintaining excellent quality. They're ideal for web use as they load faster.

Can I batch convert multiple images?

Yes! Simply select multiple images when uploading, and they'll all be converted to your chosen format. You can download them individually or as a ZIP file.
