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, reliable HEIF to PNG conversions tailored for batch workflows and color-accurate outputs

Fast Batch Processing

Convert dozens of HEIF images in parallel using optimized browser-side routines for quick throughput.

Lossless PNG Output

Produce lossless PNG files suitable for editing and print where HEIF lossy compression would be undesirable.

Broad Device Support

PNG target ensures universal desktop, mobile, and web compatibility when HEIF is unsupported.

Client-Side Processing

Files are decoded and encoded in the browser memory to reduce external upload exposure.

Alpha & Transparency Handling

Preserves HEIF alpha when present by mapping transparency to PNG; verify per-file results.

Efficient Workflow Controls

Adjust output resolution and process large sets with consistent per-image timing for planned jobs.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare HEIF Sources

Inspect HEIF for embedded alpha or auxiliary images before batching to decide per-file export behavior
Normalize EXIF orientation in HEIF files to avoid manual rotations after PNG rasterization
Check HEIF bit depth and downsample nonstandard depths only if target tools require 8/16-bit PNG
Separate animated HEIF into frame sequences prior to batch to retain temporal ordering
Validate camera-specific HEIF variants (Apple vs Android encodings) to anticipate metadata differences

Manage PNG Outputs

Estimate storage for PNG outputs since lossless conversion expands HEIF compressed sizes
Group outputs into ZIP archives to reduce transfer overhead for large batches
Enable 16-bit PNG only when editing software supports it to avoid unnecessary size increases
Keep originals when converting for archival so HEIF compressed masters remain available
Label batch exports with resolution and bit-depth metadata for downstream asset management

Validate Post-Conversion

Compare color using embedded ICC chunks and proof in target editor to confirm gamut mapping
Open converted PNG at 100% zoom to inspect edge artifacts from HEIF decoding
Verify alpha channel presence by toggling backgrounds in an editor for compositing checks
Confirm important EXIF fields (capture time, orientation) are present in PNG text chunks
Run checksum comparisons for automated batch pipelines to ensure file integrity

Batch Performance & Privacy

Process groups of 20-50 HEIF files to balance memory use and throughput in the browser
Close other CPU- and memory-heavy tabs to improve conversion speed and reduce swap
Keep sensitive HEIF sources local; conversion occurs in-memory to limit external exposure
Monitor available disk space before exporting large PNG batches to avoid incomplete writes
Schedule large exports during off-peak hours to prevent device overheating on mobile

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.
