How it works

  1. Choose files from your device, drag them here, or paste an image.

  2. Adjust the available settings and inspect your results before downloading.

  3. Download the result or copy your colors. No account or payment is required.

When to use it

iPhone photos on Windows

Windows apps and many websites cannot open HEIC. Convert photos copied from an iPhone to JPG so they open everywhere.

Upload forms and marketplaces

Most upload forms reject HEIC. Convert first, then use Compress Image to 100KB if there is also a size limit.

Sharing and printing

Send JPGs to friends, clients and print services that do not support Apple's photo format.

What to expect

HEIC photos are decoded in your browser with the open-source libheif library, so they also work in Chrome, Edge and Firefox on Windows and Android. Output is JPG at quality 90 by default, with orientation applied. Photos up to 12 megapixels are supported, which covers standard iPhone photos.

Limits apply to both input and output. Animated images are not supported. Files remain in memory only; reloads clear your work. Smaller batches help on mobile devices.

HEIC decoding uses the open-source library libheif (LGPL-3.0).

Frequently asked questions

What is a HEIC file?

HEIC (High Efficiency Image Container) is the photo format iPhones use by default. It keeps files small, but Windows, Android apps and many websites cannot open it.

Are my photos uploaded to convert them?

No. HEIC decoding runs in your browser with libheif compiled to WebAssembly, so photos never leave your device. The decoder is downloaded once, the first time you convert.

Will the JPG keep the photo quality?

At the default quality of 90 the JPG looks the same as the original in normal viewing. The file is usually larger than the HEIC because JPG compresses less efficiently. Lower the quality for smaller files.

Why was my HEIC photo rejected?

Live Photos videos, image sequences and photos above 12 megapixels, such as 48 MP HEIF Max photos, are not supported. Export a standard photo from your iPhone or reduce its resolution and try again.

Are my images uploaded?

No. Image processing takes place in your browser. Files are not sent to Codia and are removed from this workspace when you refresh or leave. Website analytics, when permitted, never contain your images or file names.

Can I process multiple files?

Yes, up to 20 files per batch, within the displayed size limits. Each file is processed separately. Download successful results individually or as a ZIP; a failed file does not block the others.

Will quality and metadata stay the same?

Results depend on the operation and settings. Lossy compression changes pixels; JPG removes transparency. Exports target ordinary 8-bit web images and do not promise EXIF, HDR, original color profiles or 16-bit preservation. Always inspect the result.
