Formats

Each format page covers uses, strengths, weaknesses, compatibility, conversion, and security. PDF conversion is intentionally not offered yet.

• JSON

  JSON is a text format for structured data. Learn what it is good at, where it fails, how to open it, and how to convert it locally with ConvertPass.

• YAML

  YAML is a whitespace-sensitive data format used for Kubernetes, CI, and config. Learn the compatibility traps, including implicit typing, and convert it locally.

• CSV

  CSV is a table as text. The hard part is quoting: commas, quotes, and line breaks inside fields. Learn how to convert it without naive splits.

• XML

  XML is a tagged document format with attributes, namespaces, and a long security history around external entities. Learn how ConvertPass maps it to JSON.

• TOML

  TOML is a configuration format with tables and a relatively small grammar. Learn how it compares with JSON and YAML, and convert it locally.

• .env

  dotenv files store KEY=value pairs for local configuration. Learn quoting rules, what ConvertPass does not expand, and why these files should stay local.

• PNG

  PNG is a lossless raster format with a chunk structure that can hold text, EXIF, and AI workflows. Learn when to use it and how to inspect chunks.

• JPEG

  JPEG is a lossy format for photographs. It has no alpha, stores EXIF including GPS, and re-encodes poorly if you stack compression.

• WebP

  WebP can be lossy or lossless and can include alpha. Browser support is now broad. ConvertPass encodes WebP when the browser can.

• AVIF

  AVIF stores stills using AV1 compression. It can be very small. ConvertPass only offers AVIF encode when this browser actually can.

• GIF

  GIF is an indexed-colour format famous for animation. ConvertPass can decode GIFs the browser can draw, but canvas conversion flattens animation to a still.

• HEIC

  HEIC/HEIF is common on iPhones and awkward on the web. ConvertPass does not advertise HEIC conversion until it can be done reliably in the visitor’s browser.

• SVG

  SVG is XML that draws vectors. It can also contain scripts. ConvertPass treats SVG as untrusted markup and does not execute it as a document.

• MP4

  MP4 (ISO BMFF) is the common video container for H.264 and AAC. Learn how it differs from WebM and MOV, and inspect files locally.

• MOV

  MOV is Apple’s QuickTime container, close cousin to MP4. Editing codecs inside MOV are a poor web delivery choice.

• WebM

  WebM is a Matroska-derived container typically holding VP8, VP9, or AV1. It is royalty-friendly on the web and less universal in editors.

• AVI

  AVI is an old Windows container. It still appears in archives. Codec support in browsers is poor; ConvertPass may not inspect the video track.

• MKV

  Matroska (MKV) can hold almost any codec. That flexibility is why browsers and some editors refuse random MKV files.

• MP3

  MP3 is lossy compressed audio. ConvertPass’s phase-one tools do not transcode audio; they may report duration when the browser can decode the file.

• WAV

  WAV usually stores uncompressed PCM. Files are large. It is an interchange format for editing, not for social video.

• PDF

  PDF is a document format that can contain text, fonts, images, and scripts. ConvertPass does not currently convert PDF in either direction, on purpose.
