How Does 2convert Work?

2convert runs a four-step pipeline that never touches a remote server. When you drop a file onto the page, the app detects its format, spawns a Web Worker, and routes the conversion to the right engine — createImageBitmap/OffscreenCanvas for images, FFmpeg.wasm for audio and video, and pdf.js / mammoth / marked / jsPDF for documents.

What Is a File Converter?

A file converter is a tool that translates a file from one format into another — for example, a PNG image into a JPG, a WAV audio clip into an MP3, or a DOCX document into HTML. Most online file converters upload your file to a remote server, run the conversion there, and email or download the result.

Which File Formats Does 2convert Support?

2convert supports 37 conversions across four categories. Images include PNG, JPG, WebP, GIF, SVG, BMP, and ICO. Audio covers MP3, WAV, OGG, FLAC, M4A, and AAC. Video supports MP4, WebM, MOV, and animated GIF output. Documents cover PDF, DOCX, TXT, Markdown, HTML, RTF, CSV, TSV, and JSON.

Is Browser-Based File Conversion Safe?

Yes. Because 2convert runs entirely client-side, your files are processed in the same sandbox as any other web page — isolated from other tabs, other origins, and your local filesystem. Nothing is uploaded, nothing is cached on a server, and nothing is logged. If you close the tab, every trace of your conversion is gone.
