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, browser-based 3FR to XV conversion optimized for web publishing and archival workflows.

Native RAW Decoding

Decodes Pentax 3FR sensor RAW data to full-color raster before XV encoding for accurate tone mapping.

High-Fidelity Output

Produces XV images that prioritize visual fidelity and minimal artifacts suitable for screen display.

Efficient Batch Processing

Process dozens of 3FR files in one session with predictable memory patterns and batching controls.

Web-Ready Targets

Generates XV files configured for web delivery, balancing compression and perceived quality for browsers.

Client-Side Conversion

Files are decoded and encoded in the browser process; no server upload required for better privacy.

Adjustable Encoding

Choose compression level and color options to control XV size versus visual detail for publication.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare 3FR for Web Rendering

Apply white balance from 3FR metadata before encoding to XV to avoid color shifts in sRGB renderers
Perform lens corrections referenced in 3FR if your workflow includes distortion correction prior to XV export
Use noise reduction on 3FR sensor data to reduce compression artifacts when XV uses aggressive quantization
Export trimmed crop regions from 3FR to reduce XV file size for thumbnails and hero images
Embed a rendered ICC profile from the 3FR processing stage when you need predictable cross-device color

Configure XV Encoding

Select moderate XV compression to retain gradients from 3FR high-bit captures without large file sizes
Enable XV alpha only if you supply a mask; 3FR sources are opaque and masks must be generated before encode
If XV supports progressive decoding, enable it for faster perceived load of 3FR-derived images on the web
Downsample very large 3FR rasters to match typical viewport sizes to save bandwidth
Compare XV outputs at 1:1 with the demosaiced 3FR raster to set acceptable compression thresholds

Integrate into Web Workflow

Use XV responsive variants derived from a single 3FR master to serve appropriate sizes via srcset
Store original 3FR files as archives and publish only XV derivatives to CDN for faster page loads
Verify XV rendering across major browsers because support and profile handling can differ
Automate sidecar creation for EXIF fields you must reattach to XV if your CMS strips metadata
Test XV fallback delivery (JPEG/PNG) for clients or browsers that lack native XV decoders

Verify Output Integrity

Compare highlight rolloff between the 3FR raw render and XV to detect clipping introduced by encoding
Check embedded timestamps and focal length transferred from 3FR EXIF to XV for catalog consistency
Inspect shadow detail at 100% to ensure quantization during XV encoding does not add banding
Validate that any applied ICC profile produced the expected render on both sRGB and wide-gamut displays
Re-run sample batches when you change XV compression settings to confirm visual expectations

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.
