Why convert HEIC to PNG instead of JPG
Both conversions make your iPhone photos compatible with Windows, Android, and web platforms. The difference is quality.
HEIC to JPG applies lossy compression. The output is compact but loses a small amount of detail. This is fine for sharing, social media, and everyday use.
HEIC to PNG applies lossless compression. Every pixel decoded from the HEIC container is preserved exactly in the PNG output. The file is larger, but the quality is the highest possible extraction from your original photo. Choose PNG when you plan to edit the photo, use it in a design project, or archive it at maximum fidelity.
How the free HEIC to PNG conversion works
OnlyFiles uses the heic2any JavaScript library to decode your HEIC file directly in your browser. The library reads the HEIC container, decompresses the HEVC-encoded image data, and outputs a lossless PNG file.
The entire process runs locally in your browser tab. No data is sent to any server. You can verify this by monitoring the Network tab in your browser's developer tools during conversion. Zero outbound requests occur.
The output PNG preserves the full color depth and resolution of the decoded HEIC image. EXIF metadata, including camera settings and date taken, is preserved when present in the original file.
HEIC to PNG vs HEIC to JPG
| Attribute | HEIC to PNG | HEIC to JPG |
|---|---|---|
| Compression | Lossless | Lossy (92% quality) |
| File size | Larger (3-8 MB typical) | Smaller (1-3 MB typical) |
| Quality | Pixel-perfect extraction | Very slight quality loss |
| Best for | Editing, design, archival | Sharing, uploading, email |
| Transparency | Supported | Not supported |
For most people converting iPhone photos for everyday sharing, HEIC to JPG is the practical choice. HEIC to PNG is the right choice when you are working on a project where quality matters, when you plan to edit extensively, or when you need to preserve the absolute best version of the image.
Common questions about free HEIC to PNG conversion
Is HEIC to PNG truly lossless?
The PNG output preserves every pixel that the heic2any library decodes from the HEIC container. No additional compression or quality reduction is applied during the conversion. The output represents the highest quality extraction possible from your HEIC file.
Why is the PNG file much larger than the original HEIC?
HEIC uses HEVC compression, which is extremely efficient. PNG uses lossless compression, which preserves more data. A 3 MB HEIC photo can produce a 6 to 10 MB PNG. This is the expected tradeoff for lossless quality.
Can I batch convert multiple HEIC files to PNG?
Yes. Drop multiple HEIC files onto the converter. Each one converts individually in your browser. All conversions happen locally with no server contact.
