Free Online File Tools
Every tool runs in your browser, so your files stay on your device. No signup, no watermark, no upload.
How FileMock Tools Work
Most online file tools upload your files to a server, process them there and send the result back. FileMock tools do the work in your browser instead, on your own computer or phone. Your files are never sent anywhere, and large batches don't have to wait for an upload.
The tools are free to use as often as you like, with no account and no watermark. New tools are added regularly.
Need Test Files?
FileMock started as a test file generator for developers and QA engineers. It creates real video, audio, image and document files of an exact size, also directly in your browser.
