About formats

TXT (Plain Text) is the most fundamental digital document format, storing unformatted text as a sequence of character codes with no embedded styling, layout instructions, or metadata beyond the characters themselves. The foundation of plain text computing traces to the ASCII standard published in 1963 by the American Standards Association (now ANSI), which defined 128 character codes including uppercase and lowercase Latin letters, digits, punctuation, and control characters. Modern plain text files typically use UTF-8 encoding, a variable-width Unicode scheme that encompasses virtually every writing system worldwide while maintaining backward compatibility with ASCII. Line endings vary by platform convention — LF on Unix/macOS, CR+LF on Windows — though most contemporary tools handle both transparently. One advantage is absolute universality — TXT files can be created, read, and edited on every computing device ever manufactured, from 1960s mainframes to modern smartphones, without any specialized software. The minimal overhead is another core strength: plain text carries zero formatting baggage, making TXT files ideal for configuration files, log output, data interchange, source code, scripts, and any context where content must be processed programmatically. Plain text serves as the substrate for structured formats like CSV, JSON, XML, YAML, and Markdown, and remains the input/output medium for virtually all command-line tools and programming environments. Despite decades of richer alternatives, TXT endures as the one truly universal document format.

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 TXT to AVIF?

AVIF offers superior compression over WEBP and JPG. Your text renders into an ultra-small, high-quality image for modern browsers.

What supports AVIF?

Chrome, Firefox, Safari (16.4+), and Edge display AVIF natively. Support is growing rapidly across platforms and apps.

How small are AVIF files?

AVIF achieves significantly smaller file sizes than JPG and WEBP at comparable quality — ideal for bandwidth-conscious use cases.

Is TXT to AVIF free?

Free conversion is available on Convertio. Premium plans offer more volume for web performance optimization workflows.

Is AVIF good for text?

AVIF lossless mode renders text with perfect clarity. Even lossy mode preserves readable text at very small file sizes.

Works on all browsers?

Major modern browsers support AVIF. For older browsers, consider WEBP or PNG as fallbacks alongside your AVIF images.
