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.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare PEF for Conversion

Confirm white balance in the PEF to avoid color shifts after demosaic during PNG export
If lens corrections are required, apply them in a raw editor before conversion to PNG
Export PEF with a chosen camera profile to control the color transform applied to PNG pixels
Crop or mask PEF frames early to reduce PNG file size and processing time
Remove bracketed or duplicate PEF captures to streamline batch conversion efficiency

Optimize PNG Output Size

Select 8-bit PNG for web thumbnails to reduce size while accepting reduced tonal depth
Use 16-bit PNG when preserving PEF's dynamic range for printing or heavy post-editing
Downscale large PEF sources to target display dimensions to minimize PNG payloads
Strip non-essential textual metadata from PNG to save bytes when EXIF is not needed
ZIP batch PNGs for faster downloads and easier CMS uploads

Verify Visual Consistency

Preview PNGs in an sRGB environment if you exported PEF to sRGB for web consistency
Compare histograms of PEF render vs PNG to check highlight rolloff and shadow detail
Confirm embedded ICC presence in PNG if color-managed rendering is required by the CMS
Inspect skin tones and focal sharpness at 100% after conversion from PEF demosaic
Open PNGs in target browsers to validate gamma and color rendering before publishing

Workflow Reliability & Privacy

Process PEF files client-side to prevent transferring raw captures over networks
Group PEFs into 20–50 file batches to balance memory use and throughput during conversion
Keep a PEF archive until after PNGs are validated so you can re-render with different settings
Close other heavy applications while converting large PEF batches to avoid browser memory limits
Download converted PNGs promptly and verify checksums if you rely on exact file transfer

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.
