Are the HEIC 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 the tool support HEIF?

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

Is PNG larger than JPG?

Usually, yes. Choose PNG for lossless quality and JPG for smaller universal photo files.

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.

Does it work on mobile?

Yes. Every tool runs on modern iOS Safari and Android Chrome. Very large files may be slower on mobile because of tighter memory limits.

Deep dive

What is HEIC to PNG?

HEIC to PNG converts iPhone HEIC or HEIF photos into PNG files. PNG is useful when you need a lossless image for editing, design tools, or workflows that reject HEIC.

FormatSwitch decodes HEIC locally in your browser and saves each photo as PNG. Your images never leave your device, even when converting a full folder.

When to use it

Open iPhone photos in apps that do not support HEIC.
Create lossless PNG copies before editing.
Prepare photos for design or document tools that prefer PNG.

How to use it safely without uploading

Drop HEIC or HEIF files and press Convert. PNG outputs are generated locally and can be downloaded one by one 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.
