PictureSharp.Heif

HEIC/HEIF support for PictureSharp, written entirely in C# with no native libraries. Requires .NET 10+ and PictureSharp 0.8.5+.

dotnet add package PictureSharp.Heif

Quick start

Register the format once, then load and save .heic files like any other image:

using PictureSharp;
using PictureSharp.Formats.Heif;

ImageConfiguration.Default = ImageConfiguration.Default.ToBuilder().AddFormat(new HeifFormat()).Build();

using var image = Image.Load("photo.heic");
image.Mutate(x => x.Resize(1600, 0));
image.SaveAsHeic("small.heic", new HeifEncoderOptions { Quality = 60 });

Rotation, crop, alpha, ICC, EXIF and XMP are applied when loading.

iPhone photos

An iPhone HEIC also holds a thumbnail, a depth map and an HDR gain map. HeifDocument reads them:

var document = await HeifDocument.OpenAsync("IMG_6655.HEIC");
HeifItemInfo photo = document.PrimaryImage;

using Image preview = document.LoadPreview(photo, new(320, 240));
using Image depth = document.LoadDepth(photo.FindDepthImage()!).ToImage();

using var withMap = Image.Load("IMG_6655.HEIC", new DecoderOptions { LoadGainMap = true });
using HdrImage hdr = withMap.ToHdr();

LivePhotoPair pair = LivePhotoPair.Read("IMG_8113.HEIC", "IMG_8113.MOV");

The Portrait blur and the Photos "Adjust" edits are not stored in the image itself. Render approximates both; you supply the slider values:

using Image edited = document.Render(photo, new HeifEdits
{
    Adjustments = new HeifPhotosAdjustments { Brightness = 25, Warmth = 10 },
    Portrait = new HeifPortraitOptions { Aperture = 2.8f },
});

Support
Read HEVC Main, Main 10 and Main Still Picture (4:2:0, monochrome); grids, alpha, rotation/mirror/crop, ICC and nclx, EXIF/XMP, Apple and ISO gain maps, thumbnails, depth, Live Photo pairs
Write HEVC Main 8-bit 4:2:0; grids, alpha, ICC/EXIF/XMP, thumbnails, ISO gain maps
Approximate Portrait blur, the 15 Photos "Adjust" sliders
Not supported image sequences, 4:2:2/4:4:4, PQ/HLG, AVIF, writing depth, metadata editing, Portrait Lighting, Photos filters and crop, Live Photo export

Limits, cancellation and TargetSize work as for the built-in formats. Decoded pixels match the HM reference decoder and libheif.

0.6.10 writes HDR gain maps: HeifEncoderOptions.GainMap (HeifGainMapMode None, Preserve, Require) saves the map attached to the image as an ISO 21496-1 tmap item, as iPhones store it, from HEIC or Ultra HDR JPEG; unedited HEIC maps are copied, others encoded at GainMapQuality. Requires PictureSharp 0.8.0. The default output is unchanged. Notes: https://github.com/art-ix/PictureSharp.Heif/blob/v0.6.10/docs/releases/release-0.6.10.md
