I built 167 browser tools that don't upload your files. Here's what I learned

The creator of toolsdocks developed 167 free browser-based tools for PDFs, images, video, audio, text, and spreadsheets to prioritize privacy. Unlike traditional online tools that upload data to servers, these tools process files locally on the user's device. This approach eliminates data leaks into logs or databases, removes upload and download wait times for large files, and avoids usage limits or signup walls, ensuring sensitive information like JWTs or customer data never leaves the device.
