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.

How to Convert Files

Follow these simple steps to convert your files

Upload Source File

Select or drag and drop your HEIF files; check sample images for expected alpha and metadata.

Adjust Settings

Pick HEIC quality preset and choose whether to include metadata boxes when offered.

Convert

Start conversion; the browser will rewrap or transcode HEIF image items into HEIC container variants.

Download Result

Save converted HEIC files or download a ZIP; inspect in target apps to confirm fidelity.

Tips and Best Practices

Optimize your conversion workflow with technical recommendations.

Prepare Source HEIF Containers

Inspect HEIF item boxes for primary image and auxiliary images before conversion to identify layers or edits
Export original camera RAW when HEIF contains non-destructive edits to avoid flattening required edits
Check for vendor-specific EXIF fields that may not map cleanly into HEIC and export them separately if important
If HEIF contains alpha, tag sample files and test conversions to confirm whether alpha channels are preserved
Normalize color space in source HEIF to sRGB or retain embedded ICC to reduce color shifts on conversion

Target HEIC Encoding Choices

Choose higher HEVC quality preset to keep chroma and detail when re-encoding HEIF imagery
Select 10-bit profiles only if target devices and editors advertise 10-bit HEIC decoding support
Prefer rewrap mode when available to avoid pixel transcoding and keep file size similar to source
Avoid aggressive compression presets that can introduce banding on low-contrast gradients
Bundle converted HEICs into ZIP when distributing to platforms that lack native HEIC support

Verify Outputs in Target Apps

Open converted HEIC in the intended mobile or desktop viewer to confirm color rendering and alpha handling
Compare EXIF camera tags and orientation values against the HEIF source to confirm correct rotation
Zoom to 100% in an editor to inspect compression artifacts introduced during HEV C re-encode
Test a representative sample of frames for multi-image HEIF sources to detect accidental flattening
Validate embedded ICC behavior by viewing in an ICC-aware editor to check color fidelity

Optimize Privacy and Performance

Process HEIF files client-side to keep camera images on device memory buffers and reduce upload exposure
Group large HEIF batches into 20–50 file sets to minimize browser memory pressure during HEIC encoding
Close memory-heavy tabs and apps before batch conversion to free CPU and avoid dropped frames
If metadata sensitivity is a concern, strip EXIF/XMP during conversion and keep originals archived offline
Download and verify converted HEIC files promptly, then clear browser temporary data to protect privacy

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.
