Advanced Compression

HEIF achieves roughly half the file size of JPEG at comparable quality. CFF to HEIF conversion creates highly efficient font image files.

Cloud Rendering

No HEIF codecs or image tools needed on your device. Convertio processes CFF to HEIF entirely on its servers from any browser.

Automatic Cleanup

CFF uploads are deleted immediately after processing and HEIF files are removed within 24 hours — total privacy for your font data.

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.

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.

Frequently Asked Questions

Why convert CFF to HEIF?

HEIF is a modern container format with advanced compression — it stores images at significantly smaller sizes than JPEG while preserving higher visual quality.

How do I open a HEIF file?

iOS and macOS open HEIF natively. On Windows, the HEIF extension is available in the Microsoft Store. GIMP and ImageMagick also support the format.

Is HEIF different from HEIC?

HEIF is the container specification; HEIC is the specific variant using HEVC codec. In practice, the terms are often used interchangeably for the same output.

Does HEIF support transparency?

Yes — HEIF can store alpha channel data, allowing your CFF font renderings to include transparency for flexible compositing and overlay use.

Is this free on Convertio?

CFF to HEIF conversion is completely free — no software to install, no account needed, just upload and download.
