What changes in a HEIC → WEBP conversion

The best target for iPhone photos headed to a website: WebP keeps the quality-to-size ratio that HEIC gave you, and every modern browser displays it.

What you lose

  • HEIC-specific depth data
  • Compatibility with print shops

What survives

  • Resolution, colour and orientation
  • Small enough files to send

Colour profile handling

The decoded image is re-tagged as sRGB, which is what browsers and forms assume. A wide-gamut source will look slightly flatter but consistent; that trade is deliberate, because an untagged file looks different on every device.

Batch conversion

Drop a folder and every supported file is converted with the same settings. Progress is per file, failed files are retryable, and the whole set downloads as one ZIP. Nothing is queued on a server, so there is no upload time and no retention window.

Frequently asked questions

Does converting HEIC to WEBP reduce quality?
Slightly. The image is decoded once and re-encoded once, which is one generation of loss. Set quality to 90 or higher to keep it invisible.
How many files can I convert at once?
Up to 200, with 4 concurrent workers. Each file keeps its own name, with the new extension appended.
Why does my HEIC file fail to open?
HEIC decoding depends on the browser. Safari handles it; Chrome and Firefox usually do not. Export the photo as JPG from the Photos app, or open this page in Safari.
Are my files uploaded?
No. The conversion runs on a worker thread inside your tab. You can verify in DevTools → Network: dropping a file produces no request.
