How do I convert CR3 files to HEIC using LetsConvert?

Upload your Canon CR3 RAW files to LetsConvert, select HEIC as the output format, and click Convert. You can batch-upload multiple CR3 images. The service uses on-device encoding to maintain your camera's original settings, and you can preview the converted HEIC files before downloading them. No software installation is required.

Why should I convert CR3 files to HEIC?

CR3 is Canon's RAW format that captures unprocessed sensor data, but it's only natively supported by Canon software and select editors. HEIC uses HEVC compression to reduce file size by up to 50% while retaining high image quality. Converting CR3 to HEIC makes your photos compatible with iOS, macOS, and Windows (with HEIF extensions), and is ideal for sharing or archiving.

What happens to metadata and color profiles when converting CR3 to HEIC?

Our converter preserves EXIF metadata, ICC color profiles, and 10-bit HDR data during the CR3-to-HEIC conversion. However, because HEIC is a compressed format, RAW-specific adjustments like white balance and exposure are baked into the output. This means you lose the ability to re-edit those parameters after conversion, so we recommend keeping a copy of the original CR3 for future edits.

CR3-TO-HEIC

Convert Canon CR3 RAW to HEIC for universal device support. HEVC compression cuts file size while preserving metadata, color profiles, and 10-bit depth.
