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?

Professional AVIF to VIFF conversion tuned for high-fidelity raster exports and technical workflows.

Fast Local Processing

Convert AVIF to VIFF quickly in-browser using optimized decoding and encoding pipelines for immediate results.

Pixel-Accurate Rasterization

Focus on maintaining chroma and luminance fidelity when rasterizing AVIF’s compressed frames to VIFF bitmaps.

Alpha Channel Awareness

Preserves AVIF alpha when target supports transparency; otherwise flattens with configurable background color.

Conversion Controls

Adjust color space handling and bit-depth assumptions to match downstream VIFF pipelines and editors.

Client-Side Safety

Files are processed in browser memory only; nothing is uploaded by default, reducing external exposure.

Workflow Integration

VIFF output is suitable for scientific imaging stacks and legacy systems that expect native VIFF raster containers.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Sources

Verify AVIF contains the expected primary frame when images were exported from encoders that produce sequences
Check AVIF color space (YCbCr vs RGB) and note any embedded ICC profile before converting
Confirm AVIF alpha exists if you need transparency and avoid flattening loss by selecting alpha-aware VIFF profiles
Downscale very large AVIFs only if target VIFF consumers require lower resolution to save disk
Extract and store AVIF EXIF/XMP separately when metadata transfer into VIFF is required

Target VIFF Encoding

Choose a VIFF profile that supports your needed bit depth to avoid quantization from AVIF 10/12/16-bit sources
If VIFF lacks alpha, select a compositing background color to control flattening outcomes
Expect larger VIFF files; plan storage and use lossless ZIP packaging for transfers
Opt for VIFF variants that accept embedded ICC if your pipeline relies on color-managed edits
When preserving scientific metadata, prefer explicit metadata embedding tools post-conversion

Integration & Editing

Test VIFF output in your analysis software before batch converting entire datasets
If downstream editors don’t accept VIFF, convert AVIF to TIFF instead for broader compatibility
Validate pixel integrity by comparing histograms between AVIF source and resulting VIFF
For animation-origin AVIFs, export each frame as separate VIFF files to preserve sequence ordering
Record conversion settings per batch so reprocessing yields reproducible outputs

Performance & Privacy

Process batches of 20-50 AVIF files to balance memory use and throughput in-browser
Keep background browser tabs closed to free RAM when decoding large AVIF bitstreams
Ensure a stable network only if you choose to upload results; local processing requires no transfer
Download converted VIFFs promptly; temporary in-memory buffers are reclaimed after session
Use sample exports to check that pixel mapping and any chosen color transforms meet acceptance criteria

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.
