How do I convert a CRW file to HEIC with LetsConvert?

Step 1: Drag and drop your CRW file (Canon Raw) into the converter. Step 2: Select HEIC as the output format and adjust the quality slider (default 90 preserves detail). Step 3: Click Convert — the raw Bayer data is demosaiced and encoded with HEVC in seconds. Step 4: Download the resulting HEIC file and import it to Photos on iPhone or macOS.

Why would I want to convert CRW to HEIC?

CRW is a Canon raw format that contains unprocessed sensor data, which is very large and requires specialized software to open. HEIC uses the HEVC codec to pack processed image data into about half the file size of a high-quality JPEG, while supporting 16-bit color depth and metadata. Converting CRW to HEIC makes your photos compatible with iOS, macOS, and many web services, and reduces storage footprint without visible quality loss at high quality settings.

What technical attributes are preserved when converting CRW to HEIC?

During conversion, the raw sensor data is demosaiced to create a full-color image. The converter preserves the original resolution, ICC color profile, and EXIF metadata (camera settings, date, GPS) in the HEIC container. Since CRW is a raster raw format, no vector geometry or layers are present, but all pixel-level detail is retained up to the selected output quality. HEIC supports 8-bit or 10-bit color depth depending on your chosen compression profile; transparency is not applicable for raw photos, and the orientation tag is copied from the source.
