Most online PDF tools quietly upload your sensitive documents, financial statements, and personal photos to third-party cloud servers. Here is how Toolwel is fundamentally different.
1. File Read from Disk
Your PDF or image is loaded.
2. Uploaded Over Public Internet
Sent to remote AWS or cloud servers. Vulnerable to interception.
3. Saved to Remote Temporary Disks
Processed on shared server hardware. Retained until background cleanup runs.
1. Direct Local Memory Load
Read directly into your browser JavaScript ArrayBuffer.
2. Local WebAssembly Processing
Processed at near-native CPU speeds inside browser Web Workers.
3. Zero Outbound Packets
Converted file is downloaded immediately from RAM. Memory is purged upon tab close.
Engineered for lawyers, medical professionals, accountants, and privacy advocates who cannot legally or ethically upload client documents to the cloud.
Every file is parsed into temporary Uint8Array buffers. When you close the browser tab or hit refresh, memory is immediately garbage collected.
We do not track file names, metadata, or document contents. No user profiling, no cookies, and no analytics inspection.
Once Toolwel loads in your browser cache, you can disconnect your internet and execute PDF and image transformations in airplane mode.
Hardened browser execution rules block unauthorized third-party scripts from reading local canvas or WebAssembly memory buffers.

Straight answers about privacy, limits and how Toolwel works.
You can check this yourself: open your browser's developer tools, go to the Network tab, and watch while you convert a file. Your file is not sent anywhere. Ads, analytics and the speed test may still make their own requests.
