All Online Tools is a collection of 262 file utilities for PDFs, images, Word, Excel, PowerPoint, OCR, archives, text and everyday calculations. The difference from most online converters is where the work happens: the processing code is sent to your browser, and your files stay on your device. There is no upload endpoint and no file storage. When you choose a file, it is read locally by JavaScript and WebAssembly, processed in a Web Worker, and handed back as a download. Nothing is transmitted, queued or retained. You can verify this yourself: open your browser's network panel while using any tool, or disconnect from the internet after the page loads, and most tools keep working.
