Apple Native

HEIC is the default format across Apple devices — WOFF font renders in HEIC display seamlessly on iPhone, iPad, and Mac.

Efficient Size

HEIC compression produces much smaller images than JPEG while maintaining excellent quality — compact font previews for sharing.

Cross-Platform Creation

Generate HEIC images from WOFF on any operating system via Convertio — no Apple hardware needed for the conversion step.

About formats

WOFF (Web Open Font Format) is a web font container format developed by Jonathan Kew, Tal Leming, and Erik van Blokland, and standardized by the W3C as a Recommendation in December 2012. The format wraps existing TrueType or OpenType font data in a compressed container with additional metadata, specifically designed for efficient delivery over HTTP as part of web pages using the CSS @font-face rule. WOFF applies table-level zlib compression to the font data, typically achieving 40-50% size reduction compared to raw TTF or OTF files, while preserving every table and glyph exactly. An extended metadata block allows foundries to embed licensing information, credits, and descriptions that travel with the font file. WOFF was created to address a practical impasse: type foundries were reluctant to allow their fonts on the web in raw TTF/OTF form (easily installable as desktop fonts), while the web standards community needed a freely implementable font delivery mechanism. One advantage is universal browser support — every modern browser across desktop and mobile platforms renders WOFF natively, making it the baseline format for web typography. The distinct file signature and container structure also provides a licensing benefit, giving foundries a format distinguishable from desktop fonts while remaining technically straightforward. WOFF 2.0, standardized in March 2018, replaces zlib with Brotli compression for an additional 20-30% size reduction and has achieved similarly broad browser adoption. Together, WOFF and WOFF2 enabled the custom web typography revolution that transformed web design from a handful of system fonts to millions of typeface options.

HEIC (High Efficiency Image Container) is Apple's branded implementation of the HEIF (High Efficiency Image File Format) standard that uses HEVC (H.265) as its image compression codec. Apple adopted HEIC as the default photo format on iPhones and iPads starting with iOS 11 in September 2017, replacing JPEG for newly captured images. HEIC files store photographs compressed with the intra-frame coding mode of the HEVC video codec, which applies sophisticated prediction, transform, and entropy coding techniques that achieve roughly 50% better compression than JPEG at equivalent visual quality. The ISOBMFF (ISO Base Media File Format) container supports multiple images in a single file, enabling Live Photos (a still plus a short video clip), burst sequences, depth maps from dual-camera systems, and HDR gain maps that allow compatible displays to render extended dynamic range. HEIC also stores alpha channels, auxiliary images for computational photography features (portrait mode depth data, semantic segmentation masks), and comprehensive EXIF/XMP metadata. One advantage is storage efficiency: iPhones shooting HEIC use roughly half the storage of equivalent JPEG captures with no visible quality loss, a significant benefit on devices where storage is finite and photos accumulate rapidly. The format's integration with Apple's ecosystem is another key strength — HEIC files are natively supported across macOS, iOS, iPadOS, and iCloud Photos, and automatic JPEG transcoding during file sharing ensures compatibility when sending photos to non-Apple devices. HEIC can also be opened by Windows 10/11 (with codec), GIMP, ImageMagick, and Adobe Lightroom.

Frequently Asked Questions

Why convert WOFF to HEIC?

HEIC is the default image format on Apple devices. Font renders in HEIC are compact and integrate smoothly into iOS and macOS photo libraries.

How do I open a HEIC file?

iPhones, iPads, and Macs display HEIC natively. Windows 10+ supports HEIC via the HEVC extension. GIMP and CopyTrans HEIC also work.

Does HEIC offer better compression than JPEG?

Yes, HEIC typically produces files 50% smaller than JPEG at similar quality — efficient storage for font glyph previews and image assets.

Does HEIC support transparency?

Yes, HEIC supports alpha channels and even image sequences, making it more versatile than JPEG for font renders needing transparent backgrounds.

Is WOFF to HEIC conversion free?

Yes, Convertio provides free WOFF to HEIC conversion online — no Apple device required for the conversion itself.
