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 BMP raster images to high-precision PFM files for photography and professional color workflows.

Fast Conversion

Quick client-side conversions leverage multi-core browsers to produce PFM outputs in seconds for typical photos.

High Precision Output

PFM stores 32-bit float per channel for high dynamic range, ideal for retaining tonal detail from BMP sources.

Editing Ready

PFM is supported by professional tools and HDR pipelines that accept floating-point raster formats.

Local Processing

Files are processed in-browser memory buffers; nothing is uploaded by default to protect originals.

Pixel-Accurate Rasterization

We rasterize BMP scanlines directly into PFM float buffers, preserving per-pixel color where possible.

Straightforward Workflow

Simple upload, optional settings, and a direct PFM download or ZIP for batch jobs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare BMP Source Structure

Verify BMP bit-depth: 24-bit RGB promotes cleanly to 32-bit float without channel remapping
If BMP contains 32-bit ARGB, confirm alpha semantics so PFM alpha receives correct transparency values
Flatten any editor-layered exports into a single BMP to avoid losing layer data during conversion
Check BMP row padding and uncommon BMP encodings; malformed headers can change pixel offsets
Standardize BMP color space externally because PFM lacks a native ICC container for automatic reattachment

Manage PFM Output Characteristics

Expect PFM size growth: 32-bit float per channel multiplies disk usage versus 8-bit BMP
Use PFM as an intermediate for HDR edits, then export to 16-bit TIFF for print-ready files
Store original BMPs alongside PFMs to retain any provenance metadata not represented in PFM
When preserving transparency, validate alpha channel interpretation in your HDR toolchain
Compress batch PFMs into ZIP archives for transfer and archival to reduce storage overhead

Integration and Workflow

Test your target editor for PFM importability; many apps require plugins or conversion utilities
In automated pipelines, convert PFM back to a color-managed format before raster-based compositing
Use PFM for floating-point blending and then tone-map to 8/16-bit outputs for distribution
Validate numeric range after conversion—some BMPs encoded with nonstandard gamma need correction
Document the conversion step in asset metadata to preserve workflow traceability across teams

Verification, Privacy and Performance

Inspect converted PFMs at 100% zoom to confirm no channel swapping or byte-order issues occurred
Run small test batches (20-50 files) to profile memory usage on target machines before full runs
Keep conversions local in-browser to reduce exposure of original BMPs when privacy is required
Close other memory-intensive apps to avoid browser swapping when processing very large BMPs
Immediately verify color fidelity on calibrated monitors as PFM float precision can reveal latent artifacts

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.
