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, browser-based CR2 to HEIC conversion tuned for web publishing and efficient storage.

Lossless / Fast Conversion

Quickly transcode CR2 raw frames to HEIC with multi-threaded in-browser processing for rapid turnaround.

Smart Image Quality

Maintain photographic detail by mapping CR2 linear sensor data into HEIC's high-efficiency codec with controlled recompression.

Batch Ready

Convert dozens to hundreds of CR2 files into HEIC archives with predictable per-image throughput and ZIP export.

Web & Device Compatible

Produce HEIC outputs optimized for modern browsers and iOS/macOS ecosystems while retaining typical web color intent.

Client-Side Processing

All decoding and HEIC encoding occur in the browser memory; files are not uploaded to external servers by default.

Adjustable Encoding

Choose quality target, chroma subsampling, and output resolution to balance file size and visual fidelity for web use.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Decodes

Apply consistent white balance in CR2 before conversion to avoid unexpected color shifts in HEIC
Export CR2 with camera-specific tone settings if you want those looks baked into HEIC pixels
Crop CR2 in advance to reduce final HEIC file size and speed up batch runs
If CR2 contains multiple raw variants, label them so conversion maps correct exposure presets
Use a calibrated monitor when adjusting CR2 decodes to ensure HEIC output matches web expectations

Control HEIC Encoding

Select higher HEIC quality to retain CR2 fine detail and minimize HEVC smoothing artifacts
Disable chroma subsampling when converting high-ISO CR2 to preserve color edges in HEIC
Limit HEIC output bit depth reduction to avoid banding from CR2 tonal data
Choose constrained resolution exports for thumbnails to lower HEIC payloads
Generate progressive HEIC-compatible previews when integrating with CMS image pipelines

Verify Metadata and Color

Check EXIF timestamps copied from CR2 into HEIC for consistency with original camera data
Confirm embedded ICC or mapped color space in HEIC matches your web display profile
Inspect HEIC at 100% to compare sharpness and highlight rolloff versus CR2 source
Validate orientation and lens tags preserved from CR2 to avoid rotated web thumbnails
Use sample images to test HEIC pipeline in your CMS before mass migration from CR2 archives

Batch Workflow Stability

Process CR2 in groups of 20–50 to balance memory use and avoid browser tab crashes
Keep originals: archive CR2 files separately since HEIC conversion flattens raw editability
Close other memory-heavy applications during large CR2-to-HEIC batches to maintain speed
Verify a subset of converted HEIC files on target devices (Safari, iOS, Chrome) after each batch
If metadata fidelity is critical, export sidecar XMP from your raw editor before conversion

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.
