About fileclay
fileclay converts and edits files in your browser. Your files stay on your device from start to finish.
What it does
Images, audio, video, documents, spreadsheets, PDFs and archives. Pick a file, choose the output and download the result.
Nineteen tools cover PDF jobs such as merging, splitting, signing and compressing, and the format guide explains 117 file types.
How it works
Most online converters upload your file, process it on a server and send back a link. fileclay has no upload step.
The page downloads a conversion engine, and that engine runs on your own device. The work uses your processor and memory, and the result is saved straight from your browser.

Check it yourself
Convert a file with your browser's network panel open. No request carries your file. You will see small analytics requests with counts and format names, described in the privacy policy.
Or convert something once, turn off your connection and convert again.
Limits
Speed and size depend on your device. Long videos on a phone are slow and can run out of memory, so fileclay warns you before it starts.
The browser version of the engine does not cover every codec combination. fileclay cannot read text from scans or edit the existing text of a PDF.
Built on
Images, audio and video rely on FFmpeg, compiled to WebAssembly. FFmpeg is not ours: it is the work of the FFmpeg project and its authors, distributed here under the GPL. PDF work relies on pdf-lib and PDF.js. All licenses and sources.
