Your input stays on your device.
When you select a file or paste text, openbhai.com processes it in your browser. Image editing, developer tools, and other file processing happen on your device. Your tool inputs are not uploaded.
Try the offline test
- Open the Watermark tool and wait for it to load.
- Disconnect Wi-Fi and mobile data.
- Choose both images, add the watermark, and download the result.
It keeps working because the processing happens in your browser. Some other tools download format-specific processing code the first time you use it; after that code has loaded, they can keep working offline too.
What uses the network?
Your browser downloads the site and the processing code it needs, including image codecs. Image-processing assets are served by the same host as this website. We also use PostHog for limited website analytics. Your files, their contents, filenames, and pasted text (including JSON, tokens, and configuration) are never included in network requests.
What is stored?
The tools hold your input in memory while you work. Developer tools do not save input history; Clear all removes input and results from the workspace. Closing the page clears the workspace. Downloads stay wherever you save them. Browser storage used for anonymous analytics is separate and never contains your files or tool inputs.
Limited analytics
We use PostHog to understand visitor counts, referring websites, countries, device and browser categories, pages viewed, and approximate time spent on pages. We collect page-view and page-leave events only. URL query strings and fragments are removed, and external referrers are reduced to their site origin. PostHog stores a random anonymous identifier in this browser for up to 30 days so repeat visits and sessions can be counted; it is not linked to a name, email address, or account.
We do not use session replay, automatic click or form tracking, heatmaps, error or performance capture, surveys, advertising tracking, or named user profiles. We do not send pasted text, tokens, file contents, filenames, form values, or tool settings to PostHog. PostHog processes technical data such as an IP address and browser information to provide coarse country and device statistics.
A note about image details
Resizing, cropping, and converting produce a new image and generally remove metadata, including camera information. Lossless PNG optimization can retain metadata; it is not a metadata-removal tool. Browser decoding can change color profiles or reduce high-bit-depth images to 8-bit color. PNG optimization preserves the original pixel data.
Simple by design
