Why PrivaUtils exists

Most online utilities require uploading your files to remote servers. When you use conventional converters or formatters, your PDFs, database exports, API tokens, and code snippets pass through third-party infrastructure where they may be logged, cached on CDNs, or stored in temporary buckets.

Modern web browsers have direct access to multi-core WebAssembly, hardware-accelerated cryptographic primitives, and Canvas pipelines. PrivaUtils runs every calculation directly inside your tab. You can disconnect your network connection, and all 18 utilities continue working without interruption.

Technical architecture

Standard browser APIs replace remote server processing.

WebAssembly (Wasm)

PDF manipulation via pdf-lib and binary operations run at near-native speed without server round trips.

SubtleCrypto API

Hardware-backed cryptographic algorithms produce SHA-256, SHA-512, and secure random passwords using your operating system CSPRNG.

Web Workers

Parsing, sorting, and regex matching run off the main UI thread so the browser interface stays responsive during heavy operations.

{ }

BigInt Precision

64-bit integer values in JSON documents are preserved as BigInt instances, preventing truncation on Snowflake and database keys.

Operating principles

Guiding standards for all utilities on PrivaUtils.

Zero data ingestion

We cannot inspect, sell, or leak user files because the application does not have an upload endpoint. Work stays inside browser memory until you choose to download or clear it.

Air-gapped compatible

No account requirements

Every tool is available immediately. There are no registrations, confirmation emails, subscription tiers, or usage quotas.

Instant access

Stable page layouts

Ad placements and dynamic panels use pre-allocated container sizes so the page content never jumps while you work, maintaining a Cumulative Layout Shift of 0.00.

CLS 0.00 enforced

Open standards and network verification

PrivaUtils is built and maintained by privacy engineers. You can inspect network traffic using your browser developer tools to verify that zero payload requests are made during any operation.
