Modern Compression

HEIC delivers smaller files than JPEG at the same quality. Converting CFF to HEIC produces efficient font images optimized for Apple devices and modern systems.

Apple Ecosystem

HEIC is the default image format on iPhone and Mac. CFF to HEIC conversion creates font renderings that integrate natively with Apple workflows.

Secure Processing

Uploaded CFF fonts are deleted right after conversion and HEIC results are removed within 24 hours — your data stays private.

About formats

CFF (Compact Font Format) is a font outline format developed by Adobe Systems around 1996 as a more efficient successor to the Type 1 font representation. CFF uses Type 2 charstrings — an optimized encoding that supports multiple arguments per operator, default value elision, and shared subroutines — to describe the same cubic Bezier glyph outlines as Type 1 but with substantially less storage. A typical CFF font is 20-50% smaller than its Type 1 equivalent. The format can function as a standalone font file or, more commonly, as the outline data table inside an OpenType font container (the CFF table in OTF files with PostScript outlines). CFF supports multiple fonts within a single file through its FontSet structure, sharing global subroutines across the collection to further reduce size. One advantage is compression efficiency without lossy degradation — every control point and hint is preserved exactly, just encoded more compactly. The format also inherits the full hinting capability of Type 1, including stem hints, counter hints, and alignment zones that ensure crisp rendering on low-resolution screens and printers. CFF2, an evolution introduced with OpenType 1.8, adds support for font variations (variable fonts) by allowing interpolation across multiple design axes. Broad support in PDF viewers, web browsers via OpenType, and professional design software makes CFF one of the most widely deployed outline formats in digital typography.

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 CFF to HEIC?

HEIC offers superior compression compared to JPEG — roughly 50% smaller files at equal quality. Ideal for font images shared within the Apple ecosystem.

How do I open a HEIC file?

Apple devices handle HEIC natively. On Windows, install the HEIF extension from the Microsoft Store. GIMP and some web browsers also support HEIC viewing.

Is HEIC widely supported?

HEIC is standard on iOS and macOS. Windows and Android support is growing. For maximum cross-platform reach, JPEG or PNG may be safer choices.

Does HEIC preserve quality well?

Yes — HEIC uses HEVC compression that preserves detail at much lower bitrates than JPEG. Your CFF glyph renderings stay sharp with smaller file sizes.

Is CFF to HEIC free?

Yes — convert CFF fonts to HEIC at no cost on Convertio, entirely browser-based with no downloads required.
