What file formats do you support?

We support over 100 file formats including images (JPG, PNG, GIF, WebP, TIFF), documents (PDF, DOC, DOCX, TXT), videos (MP4, AVI, MOV), audio (MP3, WAV, FLAC), and many more specialized formats.

Yes, absolutely. We use enterprise-grade encryption for all file transfers. Your files are automatically deleted from our servers after conversion, and we never store or access your personal data.

What is the maximum file size?

The maximum file size for free users is 100MB per file. Premium users can convert files up to 1GB. For larger files, we recommend our batch processing feature.

How long does conversion take?

Most files convert in under 30 seconds. The exact time depends on file size and format complexity. Our advanced algorithms ensure the fastest possible conversion while maintaining quality.

Can I convert multiple files at once?

Yes! Our batch processing feature allows you to upload and convert up to 50 files simultaneously. This is perfect for bulk conversions and saves significant time.

Do I need to create an account?

No account is required for basic conversions. However, creating a free account gives you access to batch processing, file history, and priority support.

Why Choose Our Converter?

Fast, reliable CR2 to HEIF conversion for sharing, editing, and storage across modern devices.

Fast Batch Processing

Quickly convert multiple Canon RAW CR2 files to compact HEIF images for faster uploads and sharing.

High Image Fidelity

Keep photographic detail via HEIF's modern compression while minimizing visible artifacts from CR2 source data.

Device-Friendly Output

Produce HEIF files optimized for iOS, macOS, and many modern Android viewers for efficient device playback.

Scalable Workflows

Handle studio batches or single-shot shoots; our pipeline scales from dozens to hundreds of CR2 images.

Client-Side Processing

Conversions run in-browser memory buffers to reduce server transfers and limit exposure of raw camera files.

Control Over Output

Adjust resolution, color rendering intent, and compression strength to balance file size and visual quality.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare RAW for Decoding

Verify CR2 white balance or supply custom white-balance values before decoding to HEIF to avoid baked-in color shifts
Apply lens corrections in your RAW editor prior to conversion because HEIF encodes a flattened raster
Merge CR2 sidecar edits into the decoded image if using nonstandard XMP tags to ensure edits appear in HEIF
Crop or rotate CR2 within the RAW stage so the HEIF output is encoded at final composition
Export demosaiced previews when needing a quick HEIF reference rather than a full RAW decode

Choose Target Encoding

Select HEIF profile with 10-bit encoding to retain more tonal range from 12–14 bit CR2 sources
Increase HEIF quality factor to reduce compression artifacts in textured shadow regions from CR2 highlights
Embed ICC profile in HEIF if you require consistent color across managed apps and devices
Avoid maximum compression when planning further edits because HEIF re-encoding can amplify artifacts
Use lossless HEIF profiles for master copies if available to keep more detail than standard lossy HEIF

Verify Visual Results

Compare HEIF output against CR2 at 100% to inspect demosaic edge artifacts and chroma interpolation effects
Check shadow noise levels post-tone mapping because CR2 noise can be amplified when mapped to lower bit depth
Open HEIF in target devices to confirm color rendering and gamut mapping match expectations
Confirm that critical EXIF fields such as GPS, timestamp, and orientation are present after conversion
If color appears off, reprocess using an alternate color matrix or embed an ICC profile during conversion

Workflow & Privacy

Keep original CR2 files archived for reversible RAW edits; HEIF is a final-raster delivery format
Process batches in groups of 20–50 CR2 files to balance memory use and speed in-browser
Avoid uploading CR2 files to third-party services when metadata sensitivity is a concern; prefer client-side conversion
Close other heavy apps to free RAM for demosaicing and HEIF encoding on resource-limited devices
Download converted HEIFs promptly and verify before deleting source CR2s if storage constraint requires removal

Fast Processing

Close unused tabs for maximum throughput.

Client-Side Privacy

No media leaves your device.

Broad Compatibility

Output files work across all operating systems.

Pro Tip

For batch conversions, process in groups of 20-50 files to optimize memory usage and avoid browser slowdowns.
