About CRW and HEIF

CRW

CRW (CRW) - Canon Raw CRW - original Canon RAW format before CR2. Best for legacy canon dslr photography, raw image processing.

HEIF

HEIF (HEIF) - High Efficiency Image File Format - container for HEVC-encoded images. Ideal for modern photography, ios/macos workflows, efficient storage and sharing.

FAQs

Is converting CRW to HEIF free?

Yes, GoConvertFile offers free conversion of CRW to HEIF for files up to 100MB. No registration required.

How long does it take to convert CRW to HEIF?

Most CRW to HEIF conversions complete within seconds for standard-sized files. Larger files may take longer depending on the conversion complexity.

What is HEIF best used for?

HEIF is ideal for modern photography, ios/macos workflows, efficient storage and sharing. High Efficiency Image File Format - container for HEVC-encoded images

Does converting CRW to HEIF lose quality?

Yes, converting CRW to HEIF uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.

What file size should I expect after converting CRW to HEIF?

HEIF files are typically 50-80% smaller than CRW files because HEIF uses efficient lossy compression. The exact reduction depends on quality settings.

Will transparency be preserved when converting CRW to HEIF?

No, HEIF does not support transparency. Any transparent areas in your CRW will be filled with a solid color (usually white) during conversion. Use PNG or WebP if transparency is needed.

What is CRW?

Canon Raw CRW — stored as image/x-canon-crw — uses lossless encoding to handle legacy canon dslr photography, raw image processing. Typical file sizes: varies by content.

What is HEIF?

HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.

When Should You Use CRW vs HEIF?

Use CRW When...

Reach for CRW when your priority is legacy canon dslr photography, raw image processing — its uncompromising quality ensures every detail is preserved.

Use HEIF When...

Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — its efficient compression makes sharing fast and storage minimal.

CRW vs HEIF: Key Differences

  • •CRW and HEIF diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Converting from CRW to HEIF changes compression type: lossy source becomes smaller but with some quality tradeoff.
  • •Transparency: Supports alpha channel transparency — converting from CRW will merge transparency into a solid background
  • •File sizes: CRW files typically range N/A and HEIF files 40-50% smaller than equivalent JPEG.
  • •Use case fit: CRW targets legacy canon dslr photography, raw image processing and HEIF targets modern photography, ios/macos workflows, efficient storage and sharing — your choice depends on which workflow stage you are serving.

Troubleshooting CRW to HEIF Conversion

  • !Converting CRW to HEIF gives blurry output → increase the quality setting before conversion
  • !Colors look different in HEIF than CRW → check color profile mismatch (sRGB vs Adobe RGB)
  • !File size changed more than expected → HEIF uses different compression, file size differences of 2-5x are normal
  • !Transparent areas in CRW turned white in HEIF → HEIF may not support transparency
