PNG to HEIC Converter

Convert large PNG images to compact HEIC files for photo storage when transparency is not required in the destination.

Shrink Photographic PNG Files with HEIC Compression

PNG is ideal for uncompressed lossless graphics, but photographic PNG files can grow exceptionally large. Converting to HEIC provides an ultra-compact storage format for photos while maintaining high visual quality on Apple devices and compatible software.

Because HEIC reader support for alpha channels varies across third-party software, this conversion flattens transparent PNG backgrounds onto a solid white background. Brand logos, cutouts, and UI interface graphics requiring alpha transparency are usually better kept as PNG, WebP, or AVIF.

Transparency: Transparent PNG areas are automatically flattened onto white. Keep your original PNG or convert to WebP or AVIF if alpha channel transparency is essential for your workflow.

What You Get Converting PNG to HEIC

Major Photo Storage Savings

Photographic PNG images become substantially smaller after modern HEIC compression, freeing up valuable storage space.

Standard RGB Output

Transparent pixels and indexed color palette images are normalized into standard RGB for predictable viewing across platforms.

Selectable Quality Controls

Fine-tune compression levels to balance image clarity and file size for web previews, photo archives, or local device storage.

Source PNG Preserved

Your original PNG file remains unchanged while a separate, optimized HEIC image is generated for download.

What to expect: The output HEIC file will usually be far smaller, but the re-encoding becomes lossy. Flat graphics, vector icons, and sharp text may show compression artifacts more readily than natural photographs.

PNG to HEIC — Frequently Asked Questions

Transparent PNG areas are automatically flattened onto a solid white background to produce consistent, broadly compatible opaque HEIC output across viewer apps.

PNG uses uncompressed lossless encoding, whereas HEIC uses advanced modern spatial compression designed specifically for high image quality at significantly smaller file sizes.

Usually, no. Vector logos, UI icons, and crisp line art retain sharper edges and full alpha transparency when kept as PNG, WebP, or AVIF. HEIC is best suited for photographic PNG images.

Yes. You can adjust compression quality settings to balance fine visual detail against smaller output file size depending on your storage needs.

Yes. The conversion retains the exact original pixel width and height of your PNG image without cropping or downscaling proportions.

Yes. Indexed color palette images and palette-based PNGs are automatically normalized into standard RGB color outputs during HEIC encoding.

Yes. You can bulk upload up to 30 PNG images in a single request (up to 25 MB per file) and download all converted HEIC files together in a ZIP archive.

Yes. All uploads are transferred via encrypted HTTPS connections and are automatically deleted from temporary server storage immediately after processing completes.

Who benefits from converting PNG to HEIC?

These are common examples; the right workflow depends on the file, required output, and your organization’s handling rules.

Apple device users

Prepare an efficient HEIC copy for compatible iPhone, iPad, and Mac workflows. A typical use is compressing lossless photo scans for a compatible archive.

Mobile content teams

Create smaller photo derivatives for storage and transfer in HEIC-aware systems. A typical use is reducing oversized PNG camera exports.

Photographers

Test a modern HEIC output while retaining the original editing master. A typical use is creating HEIC copies for storage on Apple devices.

App testers

Prepare sample HEIC assets for upload, preview, and compatibility checks. A typical use is your original PNG file remains unchanged while a separate, optimized HEIC image is generated for download..
