About formatdeck

formatdeck is an independent collection of small tools for getting a file into the form you need. It is built and maintained by Nityananda Gohain.

A tool for the task in front of you

Open an iPhone photo in software that needs JPG. Get an image below an upload limit. Cut a section from a video or clean up pasted text. Each tool starts with the task, without an account or a queue.

Your browser does the processing

The website delivers the tool; your device does the work. Image tools use WebAssembly builds of established image libraries. The video cutter uses browser media APIs and an optional local FFmpeg engine. Text cleanup runs in JavaScript. Processing code is loaded when needed to keep the first page light.

This approach keeps file contents on your device and makes batch work possible without a server upload. Large files can still reach your browser’s memory or codec limits. The licences page lists the libraries that make these tools possible.

Clear results, including the tradeoffs

Converting a format can change quality, transparency or metadata. Compression can reduce pixel dimensions to meet a byte limit. Image results show the actual download size, dimensions, alpha-channel status and whether EXIF is present, so you can check what you are saving.

Local file processing and website measurement are separate. The privacy page explains the site’s analytics and gives you a Google Analytics preference control.
