Free, private, and instant — your files never leave your device.

HEIC (High Efficiency Image Container) is the default photo format on iPhones since iOS 11, using HEVC compression to halve the file size of an equivalent JPEG. Outside Apple's ecosystem, HEIC is nearly unusable: Windows requires a paid codec, Android cannot open it at all, and no web platform or email client accepts HEIC natively. WebP is accepted by all major browsers and modern CMS platforms, and it typically produces files 25–34% smaller than JPEG — making it the right format when you want an iPhone photo on a web page. The output will typically be somewhat larger than the HEIC — HEIC's HEVC compression is extremely efficient — but the compatibility gain far outweighs the size difference.

When you’d want this conversion

  • Sharing iPhone photos with Windows or Android users who cannot open HEIC
  • Uploading to social media, cloud storage, or web platforms that reject HEIC files
  • Publishing iPhone photos directly to a website or CMS
  • Reducing photo file size for web delivery — WebP is typically 25–34% smaller than JPEG

What to watch for

Both formats are lossy — re-encoding applies compression twice. Start from the highest-quality source you have and keep the quality slider at 80%+ to minimise compounding artifacts.
Your browser must support HEIC decoding. Safari on macOS handles it natively; Chrome and Firefox may require a recent OS with HEVC codec support.

How to Convert HEIC to JPG

How to Use

  1. 1

    Drop your HEIC file or click to browse — the output format is already set to WebP.

  2. 2

    Adjust the quality slider. 85–90% is a good starting point; lower values produce smaller files with more visible compression.

  3. 3

    Click "Convert to WebP" — conversion runs entirely in your browser.

  4. 4

    Download the WebP.

Frequently Asked Questions

How much smaller will the WebP be compared to the HEIC?

Typically 25–34% smaller at equivalent visual quality. Exact savings depend on image content; natural scenes compress more than high-frequency graphic detail.

Are my iPhone photos private when I use this converter?

Yes. All HEIC decoding and re-encoding runs entirely in your browser. Your photos are never uploaded to a server — they are read, processed, and exported locally on your device, and nothing leaves it.

Can I stop my iPhone from shooting in HEIC?

Yes — go to Settings → Camera → Formats and choose "Most Compatible." Your iPhone will shoot JPEG from that point on. For existing HEIC photos already on the device, conversion is the only option.
