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 raw DNG camera files to XPM for legacy compatibility and simple raster archiving without server uploads.

Fast Local Processing

Client-side conversion runs quickly in-browser using optimized decoding and rasterization pipelines.

Pixel-Accurate Rasterization

We render DNG sensor data into full-resolution bitmaps before encoding to XPM to preserve visible detail.

Legacy Format Support

XPM produces simple, widely readable ASCII or binary pixmap files for older tools and X11 environments.

Client-Side Privacy

Files are processed in browser memory; no DNG source leaves your device unless you download results.

Batch Conversion Ready

Queue multiple DNGs for sequential rasterization and XPM export with predictable memory usage.

Control Output Size

Choose export resolution to balance XPM file size versus archive fidelity for long-term storage.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Raw Development

Apply consistent white balance in your raw editor so the rasterized XPM reflects the intended neutral tones
Export a verified preview or flattened TIFF if you need exact tonal reproduction in addition to XPM
Embed or export ICC profiles separately before conversion because XPM cannot store them reliably
Bake lens corrections and noise reduction into the DNG-derived bitmap to avoid inconsistent raster results
Save sidecar XMPs to retain edit parameters that XPM will not carry

Manage Output Encoding

Select lower resolution when XPM size matters because XPM stores raw pixels and grows quickly with dimensions
Use indexed color or palette reduction when acceptable to shrink XPM footprints for archival delivery
Normalize dynamic range in the DNG development step to prevent banding after 8-bit conversion
Test representative scenes to choose dithering or quantization settings prior to batch export
Compress output ZIP archives for long-term storage instead of relying on XPM internal size

Verify Visual Fidelity

Compare histogram of the rasterized XPM against the developed DNG to detect clipping introduced by 8-bit conversion
Inspect shadow and highlight details at 100% to confirm demosaic and tone mapping results
Check that any transparent regions map to the XPM transparency index and are not partially alpha-blended
Open XPM in target legacy software to validate color rendering without ICC support
Spot-check several images from each camera model, since DNG variants can differ in embedded matrices

Workflow Robustness

Process large batches in groups of 20–50 DNGs to limit browser memory spikes and ensure consistent exports
Keep original DNGs archived alongside XPMs because XPM cannot reproduce raw development steps later
Use checksum or manifest files to verify batch integrity after conversion
Close unnecessary browser tabs and free memory to reduce conversion failures on mobile or low-RAM devices
Download converted archives promptly; relying on cached browser state risks accidental loss

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.
