How does the format converter work?
This tool uses your browser's built-in Canvas API to decode your image and re-encode it in the format you choose. The entire process runs locally on your device — your images are never sent to any server.
Frequently Asked Questions
Why convert image formats?
Different formats have different strengths. JPEG is best for photos (small size, universal support). PNG preserves transparency and is lossless. WebP offers the best compression-to-quality ratio and is supported by all modern browsers.
Can I convert multiple images at once?
Yes! You can select or drag & drop multiple images at once. They will all be converted to the format you choose. Use the "Download All" button to save them all at once.
What happens to transparency?
PNG and WebP support transparency. If you convert a transparent PNG to JPEG, the transparent areas will become white since JPEG does not support transparency. To preserve transparency, use PNG or WebP as your output format.
