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 SGI conversion tailored for photographers and legacy workflows

Fast AVIF Decoding

Efficient AVIF decoding pipeline converts modern compressed images quickly for immediate use in legacy SGI format.

High Fidelity Rasterizing

Preserves pixel-level image detail when rasterizing AVIF's compressed frames into SGI's uncompressed bitmap structure.

Legacy SGI Output

Produces .sgi/.rgb files compatible with older imaging tools and renderers that expect raw raster buffers.

Color Handling

Converts sRGB and profile-less AVIF sources into SGI raster while noting color profile embedding limitations.

Client-Side Processing

All decoding and re-encoding run in your browser session memory, minimizing external upload exposure.

Uncompressed Archive Ready

Outputs are uncompressed SGI files suitable for archival, editing pipelines, or image stacks in DCC tools.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Sources

Verify AVIF bit depth and choose files with intended 8/10/12-bit channels to avoid unexpected quantization
Flatten layered exports before AVIF creation because AVIF is already a flattened container and layers cannot be recovered
Extract EXIF/XMP from AVIF if you require camera metadata preservation since SGI lacks standard metadata containers
Keep original AVIF ICC profiles as sidecar files to maintain color fidelity after SGI conversion
Trim or select the desired AVIF frame when source is animated because only one frame will become the SGI image

Target SGI Considerations

Choose 16-bit SGI when converting 10/12-bit AVIF to reduce banding risk; verify your SGI consumer accepts 16-bit
Expect file size expansion: provision storage because SGI stores uncompressed raster buffers
Map AVIF alpha to SGI alpha plane only if downstream software supports it; otherwise export a separate alpha file
If you need embedded profiles, store ICC sidecars alongside SGI because embedding is not standardized
Use lossless intermediate steps when further editing to avoid iterative quality loss after conversion

Workflow Integration

Test SGI output in your target editor (e.g., legacy renderers or compositors) before batch processing
Automate verification by comparing histogram and channel values between AVIF source and SGI result
When integrating into DCC pipelines, keep naming conventions consistent for frame sequences converted from animated AVIF
Use checksum or file-size checks to detect truncation issues after large batch downloads
If color-critical, perform soft-proofing in the SGI-consuming application referencing the source ICC profile sidecar

Performance & Privacy

Process batches in groups of 20-50 AVIF files to balance memory use and speed in-browser
Close other memory-heavy tabs to prevent browser process eviction during large AVIF decodes
Confirm network stability before downloading expanded SGI archives to avoid incomplete downloads
Handle sensitive camera metadata locally — extract and store before conversion if retention is required
Clear temporary conversion buffers in the browser after download to reduce local memory footprint

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.
