Photo privacy tools
JSON tools
Why use private browser tools?
Photos, contracts, and pasted JSON can contain information you would rather not send to an unknown server. Local File Tools performs the work in your browser, so you get the convenience of an online tool without transferring the input itself.
Nothing is uploaded
This is a static site with no server that accepts your files or pasted data. Processing runs in your browser, with expensive work isolated in Web Workers.
No account or tracking
Use every tool without registering. There are no analytics, tracking pixels, first-party cookies, or third-party fonts.
Frequently asked questions
Is this actually free?
Yes. Every tool is free to use without an account, subscription, daily quota, or watermark. Each tool page explains its relevant size and batch limits.
Do I need to install anything?
No. It runs in the browser tab you already have open. There is no app or extension to install.
Which browsers are supported?
Any current version of Chrome, Edge, Firefox, or Safari. The image and PDF-rendering tools need OffscreenCanvas support, available in Safari 16.4 and later.
How is this different from other online tools?
Many online tools send files or pasted data to a remote server. These tools process the input on your device instead, and the public source code makes that privacy boundary inspectable.
