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, transparent VIFF to PNG conversions with clear tradeoffs between fidelity and file size for image workflows

Fast Rasterization

Convert VIFF packed pixel streams to PNG bitmaps quickly using optimized browser decoding and single-pass encoding.

Preserve Visual Fidelity

Maintain native pixel values and gamma where possible; avoid unnecessary resampling to retain VIFF detail.

Broad PNG Support

Output PNGs open in editors, web browsers, and CMS platforms without special plugins or wrappers.

Client-Side Processing

Files are processed in-memory in your browser session so original VIFF data is not uploaded to external servers.

Adjustable Output

Choose transparency handling and bit-depth flattening options to balance file size against editing flexibility.

Ideal for Archival or Editing

Produce lossless PNGs suited for archival workflows or downstream raster editors like GIMP and Photoshop.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare VIFF Source Structure

Inspect VIFF header to confirm bit depth and alpha presence before conversion
Flatten or export specific VIFF layers you need preserved into separate files
If VIFF contains multiple frames, export the intended frame to avoid accidental flattening
Normalize premultiplied alpha in VIFF to ensure correct RGBA conversion into PNG
Extract embedded ICC or XMP from VIFF when color-critical workflows require reattachment

Choose PNG Encoding Strategically

Select 16-bit PNG when VIFF contains high dynamic range to avoid quantization loss
Prefer 8-bit PNG when file size is critical and the source tonal range permits downsample
Enable PNG filtering for better compressibility on photographic VIFF content
Omit alpha in PNG exports if VIFF alpha is not meaningful to reduce file size
Compress batch outputs into ZIP when storing converted PNG archives for distribution

Verify Output in Target Tools

Open converted PNG in a color-managed app to confirm ICC mapping from VIFF
Check transparency edges at 100% zoom to detect premultiplied alpha artifacts
Compare histograms of VIFF and PNG to spot banding after bit-depth changes
Validate dimensions and aspect ratio to ensure VIFF pixel geometry was preserved
Test PNG import into the intended CMS or editor to confirm compatibility

Workflow Safety and Performance

Process VIFF batches in groups of 20–50 to prevent browser memory pressure
Keep original VIFF archives until PNG outputs are validated for editorial needs
Close memory-heavy browser tabs during large conversions to maintain speed
Use local editors for any post-conversion color grading to avoid re-encoding losses
Download converted PNGs promptly and clear temporary in-memory buffers

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.
