HEIC → JPG/PNG Converter — About

What this converter solves

Apple's devices capture photos as HEIC to reduce storage usage and preserve features like Live Photos. Many web apps, CMS platforms, and legacy DAM systems still expect JPG or PNG uploads. The converter bridges that gap without exposing private media to third-party services.

Designers and QA teams also use it to normalize assets before handing them to clients or automation suites. Because everything runs locally, you can review sensitive shots on shared workstations with confidence.

How the conversion pipeline works

When you add files, the tool streams each HEIC into a WebAssembly decoder based on libheif. The decoded bitmap is then re-encoded using MozJPEG for JPG exports or a pure JavaScript PNG encoder. Temporary buffers are released immediately after download links are generated.

Optional metadata preservation copies over core EXIF fields by parsing them from the original container and writing them into the JPG output. This keeps capture time, device model, and orientation intact for systems that rely on those fields.

Operational best practices

• Batch up to 20 photos at a time for the smoothest experience on mid-range laptops.
• Use the quality slider to balance fidelity and file size when preparing social media or marketing assets.
• Disable metadata when sharing imagery externally to avoid leaking location or device information.
• Archive original HEIC files if you need to re-export in a lossless format later.

Support and roadmap

Future updates will improve ZIP performance, add drag-to-reorder batch queues, and explore AVIF output once browser support is more consistent. Share feedback through the contact form linked in the site footer so the roadmap can prioritize your workflows.
