Convert HEIC to PEF
Fast, free, and secure HEIC to PEF conversion. No registration required.
A fast, free heic to pef conversion tool that works offline — your files stay on your device from start to finish. HEIC Image was designed for iPhone and iPad photography, Apple Photos library storage. By converting to PEF Raw Photo, you unlock Pentax camera users and RAW photography processing. This conversion bridges two ecosystems: MPEG/Apple's HEIC Image and Ricoh/Pentax's PEF Raw Photo. Xonvert supports batch conversion — convert multiple files at once and download them all as a ZIP.
Why Choose PEF Format for Your HEIC Files?
There are strong reasons to convert HEIC to PEF:
Metadata handling: PEF Raw Photo has robust metadata support, allowing you to embed titles, tags, and descriptions that travel with the file.
Industry standard: In many image workflows, PEF Raw Photo has become the go-to format, making this conversion a frequent necessity.
API and automation: Many automated workflows and APIs expect PEF Raw Photo as input, making this conversion necessary for programmatic processing.
Editing flexibility: PEF Raw Photo files can be opened in a wider range of editing software, giving you more options for further modifications.
Collaboration ease: Team members and collaborators are more likely to have software that opens PEF Raw Photo natively, reducing compatibility friction.

Conversion Quality Deep Dive
HEIC Image encodes data using perceptual compression that prioritizes human perception. PEF Raw Photo prioritizes exact data preservation. The conversion maps between these approaches intelligently. HEIC Image's known limitation — limited Windows, Android and web browser support — is resolved when converting to PEF Raw Photo, which offers full sensor data from Pentax DSLR and mirrorless cameras. The HEIC Image source uses lossy encoding. The PEF Raw Photo output uses lossless encoding. This difference in compression approach means Xonvert carefully manages the transition to preserve maximum fidelity.
Converting between image formats is one of the most common file operations. When moving from HEIC Image to PEF Raw Photo, key considerations include color depth preservation, transparency support, and compression artifacts. Since HEIC Image is lossy while PEF Raw Photo is lossless, the conversion will perfectly preserve your current image data without further degradation — though it cannot restore details lost during the original HEIC Image compression.
Important: Converting from lossy HEIC to lossless PEF does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original HEIC encoding cannot be recovered.
