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, batch-oriented BMP to SIX conversion with clear behavior notes and productivity-first controls.

Fast Batch Processing

Parallel in-browser conversion accelerates large BMP batches without server uploads or waits.

Predictable Raster Output

Converts BMP pixels to SIX raster frames with minimal interpolation and controlled sampling.

Scale-Friendly Workflows

Designed for 10–200 image batches, keeping per-image latency low and throughput consistent.

Wide SIX Target Support

Produces SIX files suitable for viewers and pipelines that accept SIX raster containers.

Client-Side Processing

All conversion runs in the browser memory, reducing external upload exposure for sensitive BMPs.

Conversion Controls

Adjust resolution and color handling; note some BMP attributes may be flattened or dropped.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Source BMP Preparation

Flatten layered editor exports to a single BMP to avoid unexpected composition changes in SIX
Convert 16-bit BMPs to 8-bit if your SIX target lacks 16-bit support to prevent silent downsampling
Embed a clear background color in BMP when alpha cannot be preserved by the chosen SIX profile
Strip unnecessary BMP palette chunks before batch conversion to reduce processing overhead
Standardize BMP DPI and dimensions to avoid per-image resampling artifacts in SIX outputs

Target SIX Encoding Choices

Select lossless SIX profiles for archival use to keep BMP detail intact during compression
Choose compressed SIX profiles to reduce size when storing many converted BMPs in archives
Enable alpha support in SIX only if source BMPs have 32-bit channels to avoid extra file bloat
Match SIX color space to BMP ICC profile where possible to minimize color shifts
Prefer SIX profiles with metadata blocks if you need to transfer simple EXIF from BMP

Verification and QA

Open sample SIX outputs in your pipeline viewer to confirm alpha and color mapping from BMP
Compare pixel-level detail at 100% to detect any compression-induced banding post-conversion
Validate metadata presence in SIX when BMP contained camera tags important to workflows
Test print or soft-proof one converted SIX file to ensure color fidelity for print jobs
Run checksum comparisons on small batches to catch accidental alterations during processing

Batch Reliability & Privacy

Group BMPs by resolution to keep memory usage predictable and avoid browser thrashing
Process 20–50 BMPs per batch to balance throughput with stable client-side memory usage
Keep original BMP archives until final SIX outputs are verified to prevent data loss
Use secure local storage practices; conversion runs in-browser but temporary files may exist in RAM
Download ZIP archives promptly and clear session caches to reduce footprint after large batches

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.
