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 PNG to XPM conversion for archival compatibility and lightweight Unix-friendly bitmaps.

Unix & X11 Ready

Convert PNG into XPM files formatted for legacy X11 toolchains and simple C-array inclusion.

Fast Local Processing

Conversions run in-browser without uploads, minimizing latency for many small PNG assets.

Predictable Raster Output

Raster pixels are translated into indexed XPM colors preserving visible color where possible.

Alpha Handling Options

Transparent and semi-transparent PNG pixels are mapped to XPM mask tokens or flattened to background.

Export Controls

Select palette size and choose whether to flatten alpha or emit a mask for compatibility.

Inspect Before Save

Preview indexed palette and mask mapping so you can verify results before downloading.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare PNG for Indexed Export

Reduce PNG color variance to simplify palette quantization and improve XPM fidelity
Flatten PNG semi-transparent regions onto a chosen background color to control XPM transparency token use
Convert PNG sRGB to the working color space before indexing to avoid unexpected palette shifts
Crop or trim PNG layers so the XPM encodes only required pixel data and smaller array sizes result
Save a copy of the original PNG with embedded ICC and EXIF for archival reference alongside the XPM

Control XPM Palette Size

Set a maximum palette count to balance XPM file size and visual accuracy during quantization
Use a shared palette for UI icon sets to ensure consistent colors across multiple XPM outputs
Prioritize critical brand colors before automatic quantization so XPM maps them exactly
When reducing palette, inspect posterization artifacts at 100% to validate acceptable tradeoffs
Export a palette map alongside XPM for reproducible reconversion or manual edits

Verify Visual & Structural Results

Preview the XPM text array to confirm width, height, and character-per-pixel encoding match expectations
Render the XPM in your target X11 tool or an XPM-aware viewer to validate transparency masking
Compare pixel-level differences between PNG and XPM with a diff or overlay to detect quantization errors
Check that any intended transparent token in XPM matches the background handling of your toolkit
Test C source inclusion by compiling a small program that loads the generated XPM to ensure syntax compatibility

Archival & Deployment Workflows

Store both PNG and XPM copies; treat PNG as the archival master due to richer metadata and alpha fidelity
Document conversion parameters (palette size, background flatten color) alongside XPM for future audits
Prefer XPM for small icons embedded in C sources, but keep PNG for print or color-managed pipelines
Automate batch conversions with consistent palette profiles to reduce drift across releases
Transfer completed XPM files over secure channels and verify checksums after deployment to systems

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.
