FREQUENTLY ASKED QUESTIONS

Everything You Need to Know About ToolLoom, Client-Side Privacy & In-Browser Tools

Yes, absolutely. ToolLoom is engineered from the ground up on modern WebAssembly and client-side web APIs. When you drop a PDF, image, video, or audio file, it is loaded exclusively into your browser's private sandbox memory. Zero bytes of your file contents, names, or metadata ever leave your computer or touch remote cloud servers.

ToolLoom compiles battle-tested C, C++, and Rust libraries—including FFmpeg, libvips, and PDFium—directly into WebAssembly (WASM). Your device's native CPU threads and GPU hardware execute the conversion, compression, and media rendering pipelines locally at near-native speeds.

Yes. Once you load a tool page, the necessary WebAssembly binaries and assets are cached by your browser. You can turn off your Wi-Fi, work on an airplane, or operate in air-gapped secure corporate networks—all processing routines continue to execute completely offline.

ToolLoom imposes zero server quotas, daily limits, or paid speed tiers. Because processing occurs directly on your machine, capacity is limited only by your device's available RAM and browser allocation. Most modern laptops and phones can effortlessly process multi-gigabyte video files and extensive document collections.

No. ToolLoom is completely frictionless. There are no mandatory account registrations, passwords, email verification links, or credit cards required. Open any tool, drop your files, apply your desired operations, and save your output immediately.

Because ToolLoom operates client-side with zero data transmission, your organization retains 100% data residency and full sovereignty. No third-party data processing agreements (DPAs) or external storage risks are incurred because your confidential legal, financial, and medical documents never traverse external networks.

ToolLoom's batch automation engine utilizes multi-threaded Web Workers to distribute computational tasks concurrently across all physical CPU cores on your hardware. This allows you to resize 300 graphics, rename archives, or convert 50 documents simultaneously without freezing your browser interface.

ToolLoom is compatible with all modern desktop and mobile browsers supporting WebAssembly, including Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, Brave, and Opera across macOS, Windows, Linux, Android, and iOS.

Yes. The PDF suite allows you to digitally sign, reorder pages, extract sections, add watermarks, and annotate contracts directly in your browser. Unlike traditional online PDF tools that upload sensitive agreements to remote clouds, ToolLoom ensures your signatures and sensitive clauses remain private.

All file buffers exist exclusively in volatile browser RAM allocated to that specific tab session. As soon as you finish your task, download your result, or close the browser tab, the allocated memory is immediately garbage collected and cleared. Zero residual data remains on disk or in cache.
