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?

Convert AVIF images to SUN format quickly and reliably, optimized for batch workflows and editing chains.

Fast Batch Processing

Process large AVIF batches with parallel transforms to SUN for rapid archival or toolchain ingestion.

High-Fidelity Raster Output

Produce SUN raster files with minimal resampling to maintain visual detail from AVIF sources.

Batch Productivity

Queue hundreds of AVIF files and export SUN counterparts with consistent parameters for bulk workflows.

Workflow Friendly

SUN outputs are tailored for legacy rendering engines and archival systems requiring Radiance-style assets.

Configurable Options

Adjust output dimensions, color handling hints, and compression policy to suit downstream SUN consumers.

Local Client Processing

Conversions run in-browser memory buffers to reduce exposure of AVIF content during large batch jobs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Sources

Inspect AVIF EXIF timestamps and export them to sidecars before conversion to SUN
Flatten layered AVIF composition in source tooling to control final raster appearance
Convert animated AVIF sequences into frame folders to avoid losing frames during SUN export
Normalize AVIF color profile to sRGB if target SUN consumers lack ICC support
Downscale oversized AVIF only when target SUN viewers have strict pixel dimension limits

Target SUN Encoding Choices

Select 16-bit raster output if downstream Radiance tools require high precision for SUN
Choose explicit background color to control how AVIF alpha flattens into SUN pixels
Enable lossless raster output to avoid re-quantization after AVIF decoding
Use consistent naming to pair SUN files with AVIF sidecar metadata for archives
Prefer ZIP packaging for bulk SUN outputs to simplify transfer and storage

Integration & Verification

Test SUN import into your target rendering engine with a representative AVIF sample
Compare pixel histograms between decoded AVIF and SUN to catch color shifts
Automate checksum or pixel-diff spot checks on batch conversion outputs
Validate dimension and DPI metadata exported as sidecars alongside SUN
Confirm file-readback on intended OS and tools before large-scale archival

Batch Performance & Privacy

Group AVIFs into 20-50 file batches to balance memory and throughput in-browser
Keep conversions local to reduce exposure; avoid uploading sensitive AVIFs to servers
Close background apps to free CPU for faster AVIF AV1 decode and SUN write
Use progressive batching and verify first batch results before proceeding
Immediately archive or encrypt SUN outputs and metadata sidecars after 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.
