Privacy Proof — No-Upload Architecture
Every tool on Toollora processes files in your browser. You can verify it yourself in under 30 seconds.
Verify it yourself (30 seconds)
You can confirm that no file ever leaves your device using your browser’s built-in developer tools:
- 1Open any tool page, for example the PDF Merger.
- 2Open the developer tools: press F12, or Ctrl+Shift+I on Windows or Cmd+Option+I on Mac.
- 3Click the "Network" tab and keep it open while you work.
- 4Drag a file into the tool and process it exactly as you normally would.
- 5Watch the request list as you work. You will see local assets load (scripts, styles, fonts) — but you will never see your file’s name, size or contents in any request. No upload endpoint exists to receive your data.
How the no-upload architecture works
All file processing is implemented with browser-native APIs that run on your own device: the Canvas 2D API for image editing, pdf-lib and pdf.js for PDF manipulation, Tesseract.js and MediaPipe WebAssembly for OCR and AI segmentation, and the Web Crypto API for hashing.
When you select a file, the browser reads it into memory locally as a File object. Everything downstream — compression, conversion, merging, rendering, recognition — happens inside JavaScript that runs on your own CPU. The result is displayed on screen or downloaded as a blob created in your browser.
A few tools download their processing engine on first use, such as the OCR language model or the AI segmentation model, from a public content delivery network. That is code downloaded to your device for processing — it is never your file, and it never uploads your data.
What we guarantee
No uploads
No Toollora server ever receives your file contents. There is no backend storage for uploaded files.
No accounts, no file tracking
Every tool works without an account. We do not log, store or fingerprint your files.
No limits, no ads
No daily usage caps and no ads around your work — local processing is free and unlimited.
Verifiable, not just claimed
You can confirm the claim yourself in the Network tab — no blind trust required.
Start with a private test
Open any tool, process a sensitive file, and watch the Network tab. You will see no outgoing file data.
