Free PDF, Video, Audio & Image Tools — Fast, Private & No Upload

File Studio is a set of everyday tools for PDFs, photos, audio and video that run inside your web browser. When you open a file in a tool it is processed on your own phone or computer and the result is handed back as a download — the file is not uploaded. There is no account and no watermark; the site is supported by ads.

Use it to get a scanned PDF under a portal's size limit, resize a photo and signature for an exam form, convert iPhone HEIC photos to JPG, sign or password-protect a PDF, or trim a voice note and compress a video for WhatsApp. Each tool page explains how the tool works, its limits, and exactly what happens to your file.

Guides

How File Studio works

The tools use browser features such as WebAssembly, the Web Audio API and WebCodecs, so the processing happens on your device. A few features need a download the first time (for example the speech-recognition model behind Auto Subtitles), and Share Files sends files directly to the device you connect to.
