Private media tools for everyday files
KlasseHand Media Tool is a collection of browser-based media utilities for everyday conversion, compression, resizing, trimming, and audio extraction tasks.
It was created to make common file chores easier for people who need a practical result quickly, without creating an account or sending every file through an upload workflow.
Most tools process selected files locally on your device using browser APIs or WebAssembly conversion libraries. That design keeps ordinary files private by default and makes the workflow transparent: choose a file, adjust settings, preview where available, and download the output.
Tools we maintain
The site focuses on practical media tasks: compressing videos to a target size, converting MOV to MP4, creating GIFs, converting GIF to MP4, extracting MP3 audio, trimming and resizing video, converting common image formats, and converting HEIC photos to JPG.
Review and maintenance
Tool pages and guides are reviewed against the current interface before publication. When a setting, output format, privacy behavior, or known limitation changes, the related page should be updated so the written guidance continues to match the tool.
Reporting problems
If a tool fails, produces an unexpected result, or a page needs a correction, contact support@klassehand.com with the page URL, browser, device, input format, and the setting you selected. Do not send private source files unless specifically requested through a support process you trust.
