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?

Reliable, camera-raw to portable grayscale conversions optimized for photographers and image pipelines.

Fast Camera-RAW Decode

Rapidly demosaic ARW sensor data so you can preview and export PGM images without long waits.

High-Fidelity Grayscale

Convert Bayer-interpolated ARW data into accurate single-channel PGM with controlled luminance mapping.

Efficient Batch Handling

Process hundreds of ARW files into PGM batches with predictable throughput and memory-aware scheduling.

Wide Editor Support

PGM output is compatible with scientific tools, legacy image viewers, and command-line image processors.

Client-Side Processing

All decoding and conversion occur locally in browser memory to reduce privacy exposure for RAW files.

Control Exposure & Gamma

Adjust basic tonal controls like exposure, white balance assumptions, and gamma before exporting to PGM.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare ARW for Grayscale

Demosaic ARW with an accurate camera profile to avoid color-to-luma artifacts
Apply linearization or camera gamma before mapping to PGM to retain shadow detail
Adjust white balance on ARW first; white balance affects luminance conversion
Remove hot/dead pixels in ARW preprocessing to prevent speckles in PGM outputs
Export exposure-corrected previews to verify highlight roll-off prior to batch export

Choose PGM Bit Depth

Select 16-bit PGM when preserving ARW dynamic range to reduce quantization error
Use 8-bit PGM only for disk-limited delivery where smaller size outweighs tonal fidelity
When mapping 14-bit ARW to 16-bit PGM, apply appropriate scaling to preserve midtones
Store original ARW alongside PGM to enable later color reconstructions or edits
Compress batch outputs into ZIP for archival while keeping PGM uncompressed for analysis

Verify Output for Workflows

Open PGM results in the analysis tool you use (MATLAB, ImageMagick) to confirm numeric ranges
Check histogram of PGM to detect clipping introduced during raw-to-gray mapping
Compare original ARW luminance samples vs PGM pixels for calibration validation
If your pipeline needs metadata, export sidecar JSON with EXIF from ARW to accompany PGM
Test a representative camera model ARW to ensure consistency before bulk processing

Performance and Privacy

Process ARW in groups of 20–50 files to balance memory and throughput in browser
Close other heavy tabs to free memory; raw decode is CPU and RAM intensive
Use local processing to avoid uploading sensitive ARW files to external servers
If networked storage is slow, copy ARW locally before batch converting to minimize I/O stalls
Download PGM outputs promptly and remove temporary browser caches to protect sensitive images

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.
