File Format Statistics 2026

Original data from the AllFileBox catalog of 147 tools across 11 categories, plus citable file format facts for journalists, researchers, and developers.

Updated 2026-05-19

AllFileBox catalog snapshot

AllFileBox ships 147 production tools as of 2026, grouped into eleven categories. Most tools run entirely in the browser; a minority require server processing for heavy operations like OCR, media transcoding, and PDF repair. The catalog is localized into 70 languages and served from a single Next.js codebase.

  • PDF — 25 tools (compress, merge, split, OCR, repair, convert to and from Word, Excel, PowerPoint, JPG, PNG, PDF/A, watermark, page numbers, organize, protect, unlock, remove metadata, flatten).
  • Image — 14 tools (JPG, PNG, WebP, HEIC, AVIF conversions plus compress, resize, crop, rotate, grayscale, watermark).
  • Text — 14 tools (word counter, case converter, JSON formatter, base64, URL encoder, HTML entities, markdown to HTML, diff, lorem, sort, deduplicate).
  • Unit converters — 8 tools (length, weight, temperature, area, speed, volume, time, data size).
  • Color — 5 tools (HEX/RGB/HSL/CMYK converter, picker, palette generator, gradient generator, contrast checker).
  • QR Code — 3 tools (QR generator, QR reader, barcode generator).
  • Developer — 15 tools (regex tester, cron generator, UUID, hash, JWT, timestamp, CSS/JS/HTML minify, YAML validator, password generator).
  • Archive — 4 tools (zip files, unzip files, extract RAR, create TAR).
  • AI — 5 tools (summarizer, translator, smart renamer, file analyzer, PDF chat) backed by Cerebras llama-3.3-70b with seven-day response caching.

Format adoption facts

PDF (Portable Document Format) was published by Adobe in 1993 and standardized as ISO 32000 in 2008. The PDF/A long-term archival profile is ISO 19005, first ratified in 2005.

HEIC and HEIF use the HEVC codec (ISO/IEC 23008-12, 2015). Apple adopted HEIC as the default iPhone camera format in iOS 11 in 2017. Most non-Apple software still requires a conversion step.

WebP was released by Google in 2010 and is supported by every major browser since 2020 (Chrome, Edge, Firefox, Safari 14, Opera). AllFileBox includes lossless and lossy WebP conversion in both directions.

AVIF (AV1 Image File Format) was standardized in 2019 by the Alliance for Open Media. Browser support reached parity in 2024. AVIF achieves roughly 50 percent smaller files than JPEG at equivalent quality.

Why browser processing is faster

AllFileBox runs heavy work directly in your browser using WebAssembly. There is no upload round trip, no queueing on a shared worker, and no rate-limited API in front. End-to-end latency scales with your device, not with our infrastructure.

  • PDF tools use pdf-lib and pdf.js compiled to WebAssembly. A 5 MB PDF compresses to roughly 30 to 50 percent of its original size depending on whether it is image-heavy or text-heavy.
  • Image tools use the Canvas API plus WebP and AVIF encoders compiled to WebAssembly. JPG to WebP typically reduces file size by 25 to 35 percent at visually equivalent quality.
  • Text tools (diff, format, validate) operate entirely in memory and never touch the network. Token-by-token diff handles 100 KB inputs without dropped frames on modern hardware.
  • AI tools call Cerebras llama-3.3-70b over HTTPS with response caching for identical prompts. The cache TTL is seven days, so popular queries return instantly after the first request.

Privacy posture in numbers

Server-side uploads are deleted within 30 minutes by a cron job that runs every 30 minutes. Browser-only tools never see file contents at the network layer. Encrypted-at-rest object storage uses AES-256. Zero contents are logged or retained beyond the cleanup window.
