How Web Pure Tools works
Web Pure Tools is built around local, browser-based processing — your files are handled on your own device.
1. You select a file
You pick a file from your device — a PDF, an image, a scanned document. Nothing is sent anywhere when you choose it.
2. Your browser processes it locally
Whenever technically possible, the operation runs directly inside your browser using JavaScript and WebAssembly. Compressing a PDF, converting an image, extracting text with OCR — it all happens on your machine.
3. You download the result
The final file is generated on your device and downloaded straight to it. No copy is kept on a server.
Do my files leave my device?
No. For the supported local tools, files are processed in your browser and are not uploaded to Web Pure Tools servers.
Are my files stored?
No. Web Pure Tools does not store, read or retain your files, because they are not uploaded for the supported local tools.
Why browser-based?
- Privacy: sensitive documents (contracts, IDs, medical notes) never leave your device.
- Speed: no waiting to upload and download large files.
- No sign up, no watermark and no artificial limits.
Limitations
Performance depends on your browser, available memory, file size and device. Very large files may be slower on older devices. This is the honest trade-off of doing the work locally instead of on a powerful server.
