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 AVIF to HDR conversion tailored for high-dynamic-range delivery and device compatibility

Optimized HDR Encoding

Convert AVIF sources to HDR-ready images with tuned tone mapping and efficient pixel pipeline for bright highlights.

Retain High Bit Depth

Preserve expanded luminance and extended color precision where possible; output targets aim to keep perceptual fidelity.

Device-Friendly Outputs

Produce HDR images compatible with HDR-capable displays and adaptive fallback for SDR devices when required.

Client-Side Processing

Conversions run in your browser memory buffers to avoid uploading source pixels, protecting privacy and speed.

Tone Mapping Controls

Adjust tone mapping strength, white point and saturation to suit target display peak luminance and viewing intent.

Alpha & Layer Handling

Alpha channels are preserved where target supports transparency; layered or animated AVIF frames are flattened.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Sources

Verify AVIF color primaries and transfer function to inform tone mapping choice
Prefer AVIF encoded at 10–12 bit depth to reduce banding when expanding to HDR
Extract and review EXIF orientation to avoid accidental rotations during conversion
If AVIF contains animation, export frames individually to retain intended temporal data
Avoid recompressing AVIF after heavy edits; use original masters for best HDR fidelity

Target HDR Encoding

Select an HDR container that supports high bit depth to store expanded luminance
Enable embedding ICC profiles when the target container and downstream tools accept them
Choose lower compression on the HDR target to preserve highlight recoverability
If alpha is required, confirm the HDR target supports transparency before export
For print or editing, prefer lossless or near-lossless settings to keep edit headroom

Workflow Verification

Preview converted HDR on both HDR display and SDR fallback to validate tone mapping
Compare histograms pre- and post-conversion to detect clipped highlights or crushed blacks
Test converted files in the target CMS or player to confirm ICC handling
Open outputs in an HDR-aware editor to ensure bit-depth and gamma are intact
When sharing, provide an SDR JPEG/PNG fallback for recipients without HDR hardware

Performance & Privacy

Process batches of 20–50 AVIF images to balance memory use and throughput
Run conversions in a single browser tab to minimize memory paging and CPU contention
Close GPU-heavy web apps to ensure available acceleration for color transforms
Keep local copies of originals; conversion cannot recover data stripped by earlier compression
Confirm downloads immediately; large HDR files can be sizable and prone to partial transfers

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.
