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 HEIC 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.
Frequently Asked Questions
Is my HEIC file uploaded to any server or cloud storage?▼
No. 100% of the conversion pipeline executes directly inside your browser using client-side WebAssembly, Canvas, and local memory. Zero bytes are transmitted across the network.
Can I adjust compression quality and scale when converting HEIC to PNG?▼
Yes. Open the settings drawer on any file item to customize compression quality (10–100%) and resolution scaling (25–200%) to balance file size and visual fidelity.
Is this HEIC to PNG converter free to use?▼
Yes, Askor Tools Universal File Converter is 100% free with no daily limits, watermarks, paywalls, or account registration requirements.
Can I batch convert multiple HEIC files into PNG simultaneously?▼
Yes. Drag and drop multiple HEIC files into the queue. The engine processes them concurrently and packages all converted PNG files into a single downloadable ZIP archive.
How does Askor Tools compare to cloud converters like CloudConvert?▼
Unlike CloudConvert or Zamzar which upload your sensitive files to remote third-party cloud infrastructure, Askor Tools runs entirely on your local device. This guarantees absolute data privacy, eliminates upload queue delays, and removes arbitrary file size caps.
