HEIC — High Efficiency Image Container

Image

HEIC compression lowers the HEVC quality factor to produce smaller files from iPhone photos while retaining their HDR color information and wide color gamut. Reducing an iPhone photo by 30–60% makes sharing in iMessage or uploading to photo services considerably faster.

up to 60%Powered by Pillow.heic

Common use cases

  • Compressing iPhone photos before uploading to cloud storage
  • Reducing HEIC files for faster iMessage and AirDrop sharing
  • Shrinking HEIC bursts and Live Photos for long-term archiving
  • Optimizing HEIC portraits for web publishing without conversion

Advantages

  • Compresses iPhone photos while preserving HDR and wide color data
  • Smaller output than JPEG at the same perceived quality
  • Supports transparency and image sequences during compression
  • Maintains EXIF metadata including GPS and camera settings

Technical details

HEIC uses the HEVC (H.265) intra-frame coding engine. Quality is controlled by a quantization parameter (QP); lower QP means higher quality and larger files. HEIC natively supports 10-bit color, HDR metadata (HLG/PQ), alpha channel, and image sequences.

Frequently asked questions

Does compressing HEIC reduce quality?

For image compression, quality depends on the setting you choose. At 75–85% quality the difference is barely perceptible. For lossless formats like PNG, compression is entirely lossless — no pixel data is discarded.

How much can I reduce a HEIC file?

HEIC files can typically be reduced by up to 60% depending on the source content and the compression level you select. Files with lots of detail compress less than simpler content.

Is my HEIC file safe when I compress it?

Yes. Your file is uploaded over an encrypted HTTPS connection, processed on our secure servers, and permanently deleted immediately after you download the compressed output. We never store or share your files.

What tool is used to compress HEIC files?

We use Pillow — a battle-tested, open-source compression engine trusted by developers worldwide — to process HEIC files reliably and efficiently.
