About MediaDocks
MediaDocks is a set of browser-based tools for working with recordings, images and documents, plus a library of guides that explain the formats behind them.
Purpose
What this site is for
Recordings are hard to search and hard to reuse. A two-hour lecture or interview holds a small amount of material you actually need, and the only way to find it is to listen. MediaDocks turns recordings into text, captions and summaries you can read, search and quote, and it covers the everyday conversions that surround that work.
The guides exist because the tools are easier to use well when you understand the choices: which subtitle format a platform wants, what a bitrate changes, why a video will not play. They are written to be read on their own.
How a guide is written and updated is described on the editorial standards page.
How it is built to behave
No media library
Files that must be processed on the server are handled in a temporary location scoped to the request. MediaDocks keeps no archive of what you upload or convert.
Work on your own files
The tools take files you provide. Many of them, such as the image, PDF and QR tools and the Background Remover, run entirely in your browser.
No account
There is no registration and no paywall. The privacy policy lists exactly which data is processed and which cookies exist.
Responsible use
You are responsible for the rights to any file you use. Rights holders can contact us through the copyright page.
What is here
The main parts of the site
Speech to text
Turns audio and video recordings into editable text with automatic language detection, and exports TXT.
Subtitles
Generates timed cues from speech or imports existing SRT and VTT files for editing, then exports SRT or WebVTT.
Audio summaries
Condenses a recording into an overview, key points, action items or question and answer pairs.
Audio extraction
Extracts the audio track from a video file you upload and returns it in the format you choose.
Images and documents
Converts and resizes images, turns PDF pages into images and images into PDFs, removes backgrounds, builds QR codes, and converts SVG and Base64.
Guides
A library of long-form explainers on video formats, codecs, bitrates, subtitles and transcription.
Responsible use and copyright
Only upload, convert or save material you own, that is licensed for your use, or that you have permission to use. MediaDocks cannot check the rights to a file, so that responsibility is yours.
If you hold rights to material and have a concern, the copyright page explains what to send and where.
