Choose up to 20 HEIC images, review the output settings and click Process images. The tool checks file contents, converts images locally and verifies the exported format and dimensions. Download one PNG image or a ZIP of completed results.
What this HEIC to PNG converter preserves
PNG avoids an additional lossy JPEG encoding step after HEIC decoding, but cannot restore detail lost in the source. PNG photos can be much larger. Only the primary still image is exported; HDR, Live Photo motion and depth layers are not preserved.
| Feature | How it works | Limit |

| Colour and metadata | Exports browser-rendered pixels; camera EXIF and original metadata are not copied | Colour, bit depth and file size can change |
How to convert HEIC to PNG online
This converter handles the complete HEIC to PNG workflow on one page, including multiple files. It does not require a desktop extension or an account.
- Choose original HEIC files or drag them into the tool.
- Review the PNG export notes and file size limits.
- Start processing. Each image shows its own completion or error message.
- Compare Original and Output, then download a file or the completed batch as a ZIP.
HEIC to PNG: quality and file size
PNG avoids an additional lossy JPEG encoding step after HEIC decoding, but cannot restore detail lost in the source. PNG photos can be much larger. Only the primary still image is exported; HDR, Live Photo motion and depth layers are not preserved.
The preview represents browser-rendered images. Keep your originals for archival storage and colour-critical work. The tool does not promise a smaller file or recover detail that was missing in the source.
Batch convert HEIC files without uploading
Files are processed sequentially in a separate Web Worker so the page stays responsive. Cancel stops the current worker and keeps completed downloads. A file that fails does not stop the rest of the batch.
Downloads remain available while this page is open. Clear all files to release their previews and results. Large batches can exceed mobile browser memory, so use fewer files if your browser stops processing.
Frequently asked questions
01Is this HEIC to PNG converter free?+
Yes. There is no sign-up, watermark or payment step. The displayed file size, image dimension and batch limits apply.
02Is HEIC to PNG better than HEIC to JPG?+
PNG is useful when you need a lossless encoding of the browser-rendered pixels or further editing. JPG is usually smaller and more convenient for sharing photographs. Neither export preserves all HEIC auxiliary data or HDR information.
03Are my images uploaded to a server?+
No. The page downloads its processing code, then reads and converts your chosen images locally. ZIP archives are also created on your device.
04Can I batch convert HEIC files?+
Yes. Add up to 20 images within the 80 MB input limit. Process the queue, then download files separately or use the ZIP button. The total generated output is limited to 120 MB.
05Why did one of my files fail?+
The tool checks actual file contents rather than trusting extensions. A mismatched format, corrupt file, animated image, unsupported HEIC variant or image over the resource limits produces a per-file error. Completed files remain downloadable.
