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 JFI Source

Export the highest-quality JFI frame from your camera or editor to avoid repeated recompression artifacts
Verify if JFI contains an alpha mask and select the frame that includes desired transparency before conversion
If JFI holds tiled vendor metadata, flatten or export a standard image layer to ensure predictable PNG output
Inspect embedded ICC profiles in JFI and choose to preserve or convert to sRGB to control color shifts
For multi-frame JFI, pick the representative frame or export frames individually to keep intended image content

Configure PNG Output

Select 8-bit channels for web delivery to reduce PNG size while preserving perceived color fidelity
Choose 16-bit PNG only if target editors support it; otherwise downsample to avoid incompatibility
Enable alpha preservation when JFI includes masks and you need transparency for overlays or UI assets
Adjust PNG filter and compression level to balance CPU time and resulting file size
When preserving ICC profile, confirm target viewer supports embedded profiles to maintain color consistency

Validation & Workflow

Open converted PNG in a color-managed editor to confirm ICC profile mapping and avoid unexpected gamut clipping
Compare pixel-level detail between JFI and PNG at 100% zoom to detect downsampling or artifacting
Check EXIF and textual chunks in PNG if provenance or capture settings must be retained for CMS ingestion
Test PNG transparency over both dark and light backgrounds to ensure mask correctness
Preview PNGs on target devices (mobile, tablet, desktop) for accessibility and responsive layout checks

Performance & Privacy

Process JFI batches in groups of 20-50 to limit peak memory usage and keep browser responsiveness
Close non-essential tabs to free memory when converting high-resolution JFI images
Use client-side conversion to avoid uploading proprietary JFI files to remote servers for privacy
Download converted PNGs immediately and archive originals to avoid accidental data exposure
When converting large archives, compress final PNG outputs into ZIP to simplify sharing

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.
