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, accurate HEIC to HEIF conversion focused on archival fidelity and broader compatibility for photography workflows.

Optimized Conversion Speed

Perform HEIC to HEIF conversion quickly in-browser with minimal latency on modern devices.

Preserve Visual Quality

Maintain chroma fidelity and perceptual quality by avoiding unnecessary recompression when possible.

Broader Device Use

Convert HEIC samples to HEIF containers for applications that prefer HEIF file naming or specific container semantics.

Client-Side Processing

Files are processed in browser memory buffers to reduce external transfer of original media.

Simple Conversion Controls

Choose basic options like output profile handling and whether to attempt metadata copying.

Archive Friendly Output

Produce HEIF files suitable for archival workflows and downstream image editors.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare HEIC Source Structure

Inspect HEIC box layout to identify primary image and auxiliary items before conversion
Export camera-specific maker notes to XMP when archival metadata is required
Separate multi-frame Live Photos into distinct files if animation must be preserved
Check for embedded alpha image items and note whether they are standard HEVC alpha representations
Verify declared color space in HEIC before conversion to prevent accidental color shifts

Target HEIF Encoding Choices

Prefer container rewrap over re-encoding to retain original HEVC pixel data when possible
If re-encoding is required, select a high-quality HEVC profile to limit additional compression loss
Embed ICC profile into HEIF metadata to improve color consistency across editors
Avoid forcing 16-bit output unless source codestream supports higher bit depth to save storage
When archiving, keep both original HEIC and converted HEIF to ensure provenance

Compatibility and Workflow Verification

Test HEIF outputs in your target CMS and editing software to confirm HEVC decoder availability
Open converted HEIF in multiple viewers to validate EXIF timestamps and orientation tags
Run pixel-level comparisons for critical images to detect recompression artifacts
Confirm that alpha or layer representation maps correctly into your compositing application
Document any tool-specific metadata mapping rules for future batch conversions

Metadata, Privacy and Performance

Extract and archive XMP/EXIF sidecar files if your workflow requires immutable metadata copies
Process batches in groups of 20–50 HEIC files to reduce browser memory spikes during conversion
Remove GPS or sensitive EXIF fields prior to public distribution when privacy is a concern
Keep originals on secure storage until converted HEIF files are validated for archival use
Use local device processing to minimize network exposure of proprietary camera data

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.
