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, reliable BMP to XBM conversions for archival compatibility and legacy system integration.

Efficient Conversion

Quickly convert BMP bitmaps to compact XBM source code for legacy C/C++ inclusion.

Legacy Compatibility

Produce XBM files compatible with older X11 toolchains and embedded UI builds.

Pixel-Accurate Rasterization

Raster pixels are mapped directly to XBM monochrome bits with predictable results.

Local Processing Option

Convert in-browser to reduce upload risk; verify outputs before distribution.

Control Dithering

Choose dithering or thresholding to manage grayscale-to-1bit conversion tradeoffs.

Embed Ready Output

Generate C-style XBM arrays ready for inclusion in source repositories.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare BMP for Monochrome Output

Convert BMP to grayscale if original color hues mislead thresholding results
Crop BMP to target icon area to reduce unnecessary XBM array size
Manually adjust BMP contrast to improve black/white separation before converting
Flatten any embedded alpha in BMP to a defined background color to control XBM foreground mapping
Ensure BMP dimensions are exact multiples required by target UI to prevent runtime scaling

Optimize XBM for Embedding

Select thresholding for silhouette icons to keep minimal ASCII size in XBM array
Use ordered dithering when BMP fine texture must be implied in 1-bit XBM
Trim BMP empty margins to shrink the generated C array and reduce binary footprint
Store original BMP alongside XBM in version control to retain full-color archival copies
Compress XBM output with repository-friendly tools or convert to header-only format for inclusion

Verify Rendering in Target Toolchain

Compile XBM into a small test program to check bit order against the display driver
Compare rendered XBM to BMP at 1:1 to validate dithering and threshold choices
Test XBM on target embedded device to confirm expected byte alignment and endianness
Inspect the XBM macros for width/height correctness to ensure layout matches UI expectations
If glyphs appear inverted, invert bits or swap foreground/background mapping before finalizing

Archival & Workflow Integrity

Retain original BMP files with EXIF and ICC as the canonical archival source for color restoration
Document conversion parameters (dither threshold, background color) alongside each XBM file
Avoid using XBM for photographs; prefer it only for icons, masks, or UI bitmaps in archives
Use batch grouping of similar BMP assets to reuse identical thresholds and ensure consistent output
Verify checksums after conversion to detect accidental truncation of ASCII XBM files

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.
