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 AVIF to MNG conversion focused on preserving visuals for multi-frame workflows and sharing.

Fast Local Conversion

Converts AVIF files to MNG quickly in your browser without uploading to a server, minimizing transfer time.

Visual Fidelity Focus

Preserves pixel data quality where possible, reducing re-encoding artifacts during AVIF→MNG raster export.

Wider Viewer Support

Generates MNG outputs intended for legacy or specialized viewers that prefer multi-frame PNG-based containers.

Batch-Friendly

Process multiple AVIF assets in a single session; optimized memory patterns for groups of images.

Client-Side Privacy

Files are processed in browser memory buffers; media does not need to be uploaded to external servers.

Adjustable Output

Choose frame order and basic export settings such as frame delay; advanced encoder controls are limited.

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your AVIF file or sequence into the converter interface.

Adjust Settings

Set frame order, frame delay, and choose 8- or 16-bit export if available in your browser.

Convert

Click convert to decode AVIF frames and encode them into an MNG container in-browser.

Download Result

Save the resulting MNG file or download a ZIP with frame previews and metadata report.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare AVIF Sources

Inspect AVIF frame timing metadata and normalize delays before conversion to avoid inconsistent MNG playback
Flatten any AVIF composition layers into explicit frames if your workflow expects discrete images
Convert HDR AVIF to a mapped SDR color space if your MNG target viewers lack HDR handling
Check AVIF alpha premultiplication settings and correct source compositing to avoid halo artifacts
Extract critical EXIF fields you rely on, since some metadata may not transfer identically

Optimize Target MNG

Choose 16-bit PNG frames when preserving high dynamic range from AVIF bit-depths is essential
Limit frame count or use frame diffs to reduce MNG file bloat for long sequences
Embed essential ICC profiles into MNG ancillary chunks when viewer color accuracy is required
Use indexed palettes for simple graphics exported from AVIF to shrink MNG size
Generate a separate static PNG fallback for viewers that cannot play MNG

Verify Across Platforms

Test resulting MNG in the exact target application or device to confirm alpha rendering
Open converted MNG in both legacy viewers and specialized image tools to check frame order
Compare histogram and highlight clipping between AVIF source and MNG output to detect tonal shifts
Confirm metadata presence in a hex viewer if provenance or copyright tags are critical
Validate playback timing on the lowest-spec device in your audience to ensure accessibility

Performance & Privacy Workflow

Process AVIF batches in groups of 20–50 to optimize browser memory and avoid tab crashes
Keep all conversion operations client-side to maintain privacy of original AVIF camera files
Close unused tabs and disable heavy extensions to free memory for high-resolution AVIF decoding
Checksum source AVIF files before conversion to detect accidental corruption prior to export
Download converted MNG immediately and archive originals to a secure storage solution

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.
