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 PNG Sources

Flatten layered PSD exports to PNG before converting to avoid losing editor layer structures
Ensure PNG alpha is correct and premultiplied state matches your target renderer to avoid halos
Convert 16-bit PNGs to a verified 8-bit preview if your HEIC encoder will downsample, then re-evaluate quality
Crop and resize PNGs to final display dimensions to reduce HEIC bitrate needs
Strip irrelevant PNG textual chunks you don't want mapped into HEIC metadata to reduce metadata mismatches

Target HEIC Encoding

Choose higher quality setting for hero imagery to avoid HEVC compression artifacts in gradients
Enable alpha encoding for assets that require transparency on supported viewers; keep a PNG fallback for unsupported clients
Test HEIC outputs on representative mobile and desktop targets to validate color and transparency rendering
Use downscaling and chroma subsampling cautiously when preserving sharp text in PNG-derived graphics
When file size matters, iterate quality settings and compare PSNR/visual artifacts against the original PNG

Workflow Integration

Include HEIC detection in your web server logic to serve PNG fallback for legacy clients using User-Agent or Accept headers
Run automated checks to confirm ICC profile mapping preserved from PNG to HEIC on CI for consistent color across releases
For CMS thumbnails, pre-generate responsive HEIC sizes from a high-res PNG master to speed delivery
Validate converted HEIC in editors like Photos (macOS) or HEIC-aware viewers to ensure expected rendering
Document which image variants in your asset pipeline should remain PNG (icons, simple UI elements) versus HEIC

Verification & Performance

Measure rendered output at 100% zoom to detect banding introduced by HEIC compression on gradients
Batch-convert representative samples to estimate memory and CPU load for production pipelines
Keep original PNG archives if exact lossless recovery is required for future edits
Prefer groups of 20-50 files per batch to maintain stable memory use during client-side conversion
After conversion, verify transparency and metadata in target browsers or image processing tools before deployment

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.
