How browser-only processing works
Core tools on this site run entirely in your browser using local memory, browser APIs, canvas, and downloadable blobs.
What we do not do
- We do not upload your files to a server for core tool processing.
- We do not log pasted text or file contents.
- We do not store processed files after the browser session ends.
- We do not send filenames to analytics.
What your browser does
- Reads files from your device only after you choose them.
- Processes JSON, CSV, YAML, and image operations locally.
- Creates downloadable files in memory using Blob URLs.
- May store optional local preferences only when you explicitly enable them in future updates.
Limitations
Very large files depend on your device memory and browser capabilities. When a file is too large, the page shows a warning before processing.
