Frequently Asked Questions

Common questions about HEIC to PNG conversion

How does in-browser HEIC to PNG conversion protect my privacy?

Unlike legacy file converters that upload your confidential files to cloud servers, OpenFileConverter runs 100% locally on your computer or phone using Rust WebAssembly. Your original HEIC files never leave your device memory, guaranteeing zero retention.

What is the main difference between HEIC and PNG?

HEIC (High Efficiency Image Container) provides apple iphone camera captures and modern high-density photo storage, while PNG (Portable Network Graphics) is optimized for logos, screenshots, graphics with transparency, and high-precision diagrams. Converting allows you to balance file size, compression fidelity, and platform compatibility.

Does converting HEIC to PNG degrade visual quality?

No. OpenFileConverter uses high-fidelity chroma subsampling with configurable quality levels (default 92%), ensuring virtually indistinguishable image fidelity with sharp edges and rich colors.

Can I convert multiple files in batch?

Yes. You can drag and drop up to 100 files simultaneously. Because processing executes in parallel on your local CPU threads, batch jobs finish in seconds without queue wait times.
