About formats

T11 (Type 11) is a PostScript font type defined by Adobe Systems as part of the CID-keyed font architecture, combining CID glyph addressing with TrueType outline data wrapped in a Type 42 PostScript shell. In Adobe's font type numbering, Types 9, 10, and 11 are CID-keyed counterparts to Types 1, 3, and 42 respectively — so Type 11 is essentially a CID-keyed Type 42, designed for TrueType fonts that contain very large glyph sets, particularly CJK (Chinese, Japanese, Korean) character collections. The format allows PostScript interpreters with TrueType rasterizer support to render CJK TrueType fonts while using CID numeric indexing instead of glyph names, which is critical for character sets numbering in the tens of thousands. Glyph outlines remain in native TrueType quadratic spline format, preserving the original hinting instructions, while the CID layer provides efficient glyph access and subsetting through CMap resources. One advantage is direct TrueType rendering quality — unlike converting TrueType outlines to PostScript cubics, Type 11 passes the original outlines to the rasterizer intact, preserving hand-tuned grid-fitting instructions. The CID indexing provides another benefit by supporting multiple encoding schemes (Unicode, national standards) mapped to the same glyph collection without data duplication. Type 11 fonts appear primarily in professional CJK print production and PDF document workflows where large TrueType-based character sets must be embedded in PostScript-derived output.

AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

Why convert T11 to AVIF?

AVIF is the newest image format backed by AV1 compression — it outperforms JPEG and WEBP in file size at equivalent quality, ideal for modern web delivery.

How do I open an AVIF file?

Chrome, Firefox, Safari, and Edge all support AVIF natively. Desktop apps like GIMP, Photoshop (via plugin), and libavif-based viewers also open AVIF.

Is AVIF better than WEBP?

Generally yes — AVIF achieves 20-30% smaller files than WEBP at similar quality. It also supports wider color gamut and HDR content.

Does AVIF support transparency?

Yes — AVIF supports full alpha channel transparency with both lossy and lossless compression modes.

Is T11 to AVIF free?

Yes, Convertio converts T11 to AVIF for free — entirely cloud-based, no codec libraries needed on your end.
