Are my photos uploaded to a server?

No. PremiumImageTools decodes and converts HEIC entirely in your browser using WebAssembly. You can even disconnect from the internet after the page loads and conversions will still work.

Does converting HEIC to JPG reduce quality?

JPG is a lossy format, so a small amount of recompression occurs. Keep the quality slider at 90% or above for visually lossless results, or choose PNG for a mathematically lossless copy.

Can I convert multiple HEIC files at once?

Yes. Drop in as many files as you like — each is converted locally and you can download them one by one or as a single ZIP archive.

How do I stop my iPhone from taking HEIC photos?

On your iPhone go to Settings → Camera → Formats and choose “Most Compatible” to record JPG instead of HEIC in the future.

HEIC to JPG / PNG / WebP Converter

Batch convert iPhone HEIC photos to JPG, PNG or WebP with a quality slider and one-click ZIP download.

Apple's HEIC format produces beautiful, compact photos on iPhone and iPad — but it refuses to open in many Windows apps, Android galleries, websites and older editing software. PremiumImageTools converts HEIC to JPG, PNG or WebP directly inside your browser, so a whole camera roll becomes universally compatible in seconds.

Unlike online converters that upload your photos to a server, this tool decodes HEIC files locally using a WebAssembly decoder. Your pictures never leave your device: there is no upload queue, no file-size cap imposed by a server, and no privacy risk. Convert a single shot or drop in fifty at once and download them individually or as a single ZIP archive.

How to use this tool

Drag and drop one or more .heic files into the upload area, click to browse, or paste with Ctrl+V.
Choose your output format — JPG for compatibility, PNG for lossless quality, or WebP for small web files.
Adjust the quality slider (1–100%) to balance file size against detail.
Click “Convert” and watch each file process locally on your device.
Download files individually, or grab everything at once with the “Download ZIP” button.

Frequently asked questions

iPhones save photos as HEIC (High Efficiency Image Container) by default. Windows and many websites require additional codecs to read HEIC. Converting to JPG or PNG solves the problem instantly and works everywhere.
