The Askor Privacy Guarantee
Traditional cloud converters require uploading your private files over the internet to remote servers, staging them in cloud storage buckets. Askor Tools eliminates that vulnerability by executing 100% of the conversion pipeline locally inside your browser sandbox.
Client-Side WebAssembly & Canvas
Your MP4 files are loaded directly into browser memory. Binary decoders and canvas engines transform data on your device without transmitting a single byte over the network.
Zero Data Retention & Zero Leaks
Because files never touch our servers, there are no databases, logs, or cloud backups where confidential legal documents, client assets, or personal records could ever be intercepted or leaked.
Zero Latency & No Queues
Cloud services place free users in slow conversion queues and bottleneck upload/download speeds. Askor Tools harnesses your local device CPU and GPU for immediate, latency-free conversions.
Truly Free & Unlimited
No daily conversion caps, no artificial file size limits, no watermarks, and no sign-up forms. Convert as many files as you need with batch ZIP packaging included.
