What This Tool Does
The converter decodes HEIC, HEIF, JPG, PNG, WebP, and AVIF locally, optionally resizes each image, and exports JPG, PNG, WebP, or AVIF. Web Workers and WebAssembly keep processing off the server.

FAQ
Are my images uploaded?
No. Decoding, resizing, conversion, and ZIP creation happen locally in your browser.
Why can AVIF conversion take longer?
AVIF encoding is computationally intensive, especially for large images and on mobile devices.
Does the converter preserve metadata?
No. Converted files do not preserve EXIF, GPS, or other source metadata, which also helps protect privacy.
What happens to transparency when converting to JPG?
JPG has no transparency. Transparent pixels are filled with the background color you choose.
