Tools for practical questions
VideoTools is built for creators who need to plan a file size, choose an export bitrate, estimate SD card capacity, or know how long an upload takes. The goal is to answer those questions quickly without creating an account or uploading media to a server.
How calculations work
All calculations run locally in your browser. Formulas and unit conversions are transparently displayed on each tool page.
Actual encodes vary with variable bitrates (VBR), codecs, metadata, and network conditions. Treat each result as a reliable planning estimate.
