Image Format Converter

Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.

Frequently Asked Questions

Which image formats can I convert between?

This tool converts between PNG, JPG, WebP, HEIC, and AVIF. Pick any input format and any output format from the two dropdowns. If you need to batch many files at once, use the dedicated Bulk Image Converter — this tool handles a single image at a time.

Will converting to JPG reduce the quality of my image?

JPG uses lossy compression, so converting from a lossless format like PNG will discard some detail that cannot be recovered. Converting between lossless formats (for example PNG to WebP lossless) preserves quality. If you need lossless output, choose PNG, WebP, or AVIF as the destination format.

Why doesn't my image have a transparent background after converting to JPG?

JPG does not support transparency. When you convert an image with an alpha channel (such as a PNG with a transparent background) to JPG, the transparent areas are flattened to a solid background. Convert to PNG, WebP, or AVIF instead to keep transparency intact.

Can I open HEIC or AVIF files on all devices?

HEIC is Apple's default photo format and works best on iPhone, iPad, and Mac — many Windows apps and older software cannot open it. AVIF is a modern, open standard supported by current browsers like Chrome, Firefox, and Safari. Converting to JPG or PNG gives you the widest possible compatibility across devices and software.

Is my image uploaded to a server during conversion?

No. Conversion happens entirely in your browser using canvas rendering — your image never leaves your device, and there is no file size limit imposed by the tool. It is fully private and works offline after the page loads.
