Online tools that process your files locally, without uploading
Most free online tools work by uploading your file or text to a server, processing it there, and sending the result back — which means your documents, photos, and data pass through infrastructure you don't control. Tabreon takes the opposite approach for most of its tools: the work happens in your browser, on your own device, so your input is never uploaded. This page lists exactly which tools run locally and which ones don't, so you can decide what is safe for sensitive files.
Where each Tabreon tool runs
| Runs entirely in your browser | Needs a brief server step | |
|---|---|---|
| Developer tools (JSON, Base64, hashes, UUIDs, JWT, and more) | Yes — input never uploaded | No |
| Text tools | Yes — input never uploaded | No |
| QR code generator | Yes — generated on your device | No |
| PDF tools (merge, split, rotate, watermark, extract, remove pages) | Yes — file never uploaded | No |
| Image resize, compress, crop | Yes — image never uploaded | No |
| HEIC, SVG-to-PNG, TIFF, GIF-to-APNG conversion | No | Yes — uploaded for the few seconds the conversion takes, then discarded |
| Feedback, early-access signup, feature-request voting | No | Yes — stores only what you submit |
