Most online tool sites upload your files to their servers, run the operation there, and send the result back. That's a lot of trust to hand a website you found through a search result.
The hidden cost of "free"
When a free tool uploads your file, you're trusting that the operator:
- deletes it promptly,
- doesn't train on it or resell it, and
- secures it in transit and at rest.
That's three promises you can't verify.
A better default
Toolknot takes the opposite approach - tools run in your browser whenever the operation allows it. Your data stays on your device, and there's nothing to leak because nothing was uploaded.
Privacy isn't an afterthought. It's the default.
When cloud processing is genuinely required (some AI tools), we're explicit about it and keep the footprint minimal. The principle stays the same: your data, your device, by default.
Frequently asked questions
What does private-by-default mean for online tools?
It means the tool processes your files locally in your browser instead of uploading them to a server, so your data never leaves your device.
Do online tools upload my files?
Most do. They send your file to a server, process it there, and return the result. Toolknot avoids this by running tools client-side whenever possible.
