Are the photos uploaded?

No. Files are processed entirely in your browser using WebAssembly and the Canvas API. Nothing is uploaded to a server, and no copy is kept once you close or refresh the tab.

Does it support HEIF as well as HEIC?

Yes. Both .heic and .heif files are supported.

Why use WEBP instead of JPG?

WEBP often creates smaller files than JPG at similar visual quality. Use JPG when you need maximum app compatibility.

Is there a watermark?

Never. FormatSwitch adds no watermark, logo, or quality cap to your output — the file you download is only what your browser produced.

Are my photos stored anywhere?

No. Files live only in your browser's memory (JavaScript heap). They disappear when you clear the queue, refresh, or close the tab. There is no server, no database, no log.

Can I convert many files at once?

Yes. Select multiple photos or drop a folder; processing is limited by your browser memory.

Deep dive

What is HEIC to WEBP?

HEIC to WEBP converts iPhone HEIC or HEIF photos into compact WEBP images. It is a good choice for websites, app assets, and photo folders where file size matters.

FormatSwitch decodes HEIC files locally and re-encodes them as WEBP in your browser. No upload is required, and batch or folder conversion keeps filenames easy to trace.

When to use it

Publish iPhone photos on a website in a smaller format.
Convert a camera-roll folder into web-ready images.
Save storage while keeping modern browser compatibility.

How to use it safely without uploading

Drop HEIC or HEIF photos and press Convert. WEBP outputs download locally, individually or as a ZIP.

Browser-based vs server-based conversion

Most online converters upload your files to their servers, process them there, and then let you download the result. That means your file exists on someone else's computer, often in logs and backups, sometimes indefinitely. FormatSwitch is different: every conversion runs on your device using WebAssembly and the browser's built-in Canvas and PDF engines. Your file never leaves your computer, so there is nothing to leak, nothing to subpoena, and nothing to trust us on — the code that does the work is running right in your tab.
