Next-Gen Web Format

AVIF is the newest web image standard with support in all major browsers. PT3 font renderings load faster than equivalent JPEG or WebP images.

Best-in-Class Compression

AVIF achieves roughly 50% smaller files than JPEG at similar quality. Your PT3 font previews are razor-sharp without wasting bandwidth.

Secure Conversion

PT3 uploads are deleted after conversion. AVIF outputs are automatically removed within 24 hours — your font data remains private throughout.

About formats

PT3 (PostScript Type 3) is a font format defined as part of the PostScript language specification, introduced by Adobe Systems in 1984. Unlike Type 1 fonts, which use a restricted subset of PostScript operators optimized for hinting and efficient rendering, Type 3 fonts allow the full PostScript language to describe each glyph. This means glyphs can incorporate graduated fills, grayscale shading, complex path operations, color, and even bitmap images — capabilities impossible within Type 1's constrained charstring interpreter. Adobe originally kept the Type 1 specification secret and proprietary, so third-party type foundries and developers who wanted to create PostScript-compatible fonts had to use the publicly documented Type 3 format during the late 1980s. A notable advantage is creative freedom: because any valid PostScript program can define a glyph, designers can produce decorative, illustrated, and textured letterforms that go far beyond simple outline fills. The format's openness was another practical strength in its era, enabling anyone to create PostScript fonts without licensing Adobe's proprietary hinting technology. However, Type 3 fonts lack the hinting mechanisms that make Type 1 text crisp at small sizes and low resolutions, which limited their use for body text. When Adobe published the Type 1 specification in March 1990, most foundries migrated to the hinted format. Type 3 fonts remain primarily of historical interest, encountered in archived PostScript documents and specialized applications where artistic glyph rendering outweighs the need for screen-optimized hinting.

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 PT3 to AVIF?

AVIF offers the best compression available today — significantly smaller than JPEG, PNG, or even WebP at equal quality. Font glyphs stay crisp and files stay tiny.

How do I open an AVIF file?

Chrome, Firefox, Safari, and Edge all support AVIF natively. GIMP, Paint.NET, and most modern image viewers also handle the format on desktop.

Does AVIF support transparency?

Yes. AVIF supports alpha transparency alongside its superior compression — your PT3 font glyphs can overlay any background without quality compromise.

Can I batch convert PT3 to AVIF?

Yes. Upload all your PT3 fonts at once — Convertio outputs individual AVIF images for each, optimized for modern web delivery.

Is this free?

Completely free. No AV1 encoder needed on your end — upload PT3 and get AVIF from any browser on Convertio.
