HEIC & Image Converter

Choose JPG and start with a high quality setting, then inspect fine texture, edges, and gradients at the size that matters. JPG re-encoding is always lossy, and no percentage guarantees that every source or viewer will look unchanged, so retain the HEIC original as the master.

No — HEIC decoding, TIFF parsing, and all encoding run in your browser, and the ZIP is built locally too. Your images never leave your device.

Yes. Add multiple files and they convert sequentially with a separate result or error for each row; completed outputs can download together as converted-images.zip. Practical batch size depends on the files and available device memory.

HEIC is a modern container commonly used for efficiently stored phone photos, while JPEG has broader support across older apps and upload workflows. Actual size and quality depend on the encoders and source; conversion is mainly a compatibility choice and creates a newly encoded copy.

AVIF output requires the browser itself to support AVIF encoding through the canvas, which not all browsers do. Where it is unsupported the file is marked failed rather than silently switching format — choose WebP as the fallback.

No — conversion goes through a canvas, which carries pixels only. Location, camera, and date metadata are not written into the output; keep originals if the metadata matters.

No. This converter fills its canvas white before drawing, so transparent regions are flattened even when the selected target can technically support alpha. Keep the original or use a transparency-preserving workflow when alpha matters.

A different format is not automatically a smaller format. Photographic pixels often grow when encoded as PNG, a high quality setting can retain more data, and the source may already be efficiently compressed. Compare the reported output size and choose the target for its destination, not for the extension alone.
