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, accurate CRW to RLE conversion for web publishing and archival workflows with clear technical guidance.

Optimized Throughput

Browser-based conversion optimized for single-file CRW inputs, minimizing wait times for web assets.

Preserve Raw Detail

Extracts sensor-derived RGB from CRW raw data to maximize tonal detail before encoding to RLE.

RLE Output for Legacy Tools

Produces RLE-packed bitmaps suitable for legacy decoders and some print workflows.

Client-Side Processing

Conversions run in the browser memory to minimize external transfer of original CRW photographs.

Accessible Controls

Basic exposure and color-space options let you influence the rasterization step prior to RLE encoding.

Direct Download

Receive a single RLE file or ZIP archive ready for immediate inclusion in web asset pipelines.

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your CRW files; large RAW files benefit from desktop browsers.

Adjust Settings

Pick target bit depth and color space; choose sRGB for web or 16-bit for archival rasters.

Convert

Start conversion; we demosaic CRW into an RGB raster then encode runs into RLE.

Download Result

Save the RLE output or a ZIP, and export EXIF sidecars if metadata is required.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare CRW for Rasterization

Apply camera white balance in CRW before demosaic to avoid color shifts in the RLE raster
Convert CRW to a linear or sRGB render intent explicitly to control tone mapping outcomes
Flatten any layered edits in your RAW editor so compositing is baked into the raster prior to RLE encoding
Export a sidecar XMP if you need to preserve original EXIF maker notes separate from the RLE output
Trim unused CRW previews to reduce memory usage during batch demosaicing

Choose Target Encoding

Select 16-bit output when preserving shadow detail from high-dynamic-range CRW files for archival RLE
Prefer 8-bit sRGB RLE for compatibility when the RLE consumer only supports standard byte-per-channel decoders
Use lossless RLE packing to avoid additional quantization after demosaicing to preserve pixel fidelity
If downstream tools require ICCs, export the profile separately since RLE embedding is not guaranteed
Match output dimensions to the intended print or web size to prevent resizing artifacts after RLE encoding

Verify Post-Conversion

Open the RLE in the target decoder to confirm channel order and expected color appearance after rasterization
Check highlights and shadows at 100% to detect demosaic-induced artifacts from CRW sensor interpolation
Confirm that any alpha you composited into the raster is represented correctly by the RLE consumer
Compare histograms between CRW-derived raster and RLE to ensure no unexpected clipping occurred
Test a sample in your web pipeline, then transcode RLE to PNG/WebP if browser delivery is required

Workflow Reliability

Process CRW batches in groups of 20–50 to balance browser memory and avoid crashes during demosaic
Close heavy GPU-accelerated tabs when running conversions to free system resources for accurate color processing
Keep original CRW files until you validate the RLE outputs and any exported metadata sidecars
Use desktop browsers for very large CRW files because mobile environments may truncate processing
Schedule verification steps in your pipeline to detect missing EXIF or ICC details early

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.
