Free HEIC to PNG Converter with Private Batch Processing
Convert HEIC to PNG online without uploading your iPhone photos. Create high-quality PNG files at the original pixel dimensions, process a batch, and download individual images or one ZIP.
Lossless PNG output
The browser preserves the decoded pixel dimensions and transparency. No quality setting is needed for PNG.
Your HEIC and HEIF files stay on this device throughout conversion.
No files selected
Conversion runs locally in your browser. Your HEIC or HEIF files never leave this device.
How to convert HEIC to PNG online
Choose HEIC or HEIF photos, run the private browser conversion, then download each PNG or save the completed batch in one ZIP file.
Choose HEIC or HEIF files
Add up to 20 iPhone photos or other .heic and .heif images, with a 25 MB limit for each file.
Convert locally in your browser
Select Convert to PNG. Each file is decoded on your device and queued separately so one invalid image does not stop the batch.
Download PNG files or a ZIP
Download results one at a time, or select ZIP after two or more images have finished converting.
Batch convert HEIC to PNG without an upload
The converter focuses on the settings people need most: a local conversion queue, original dimensions, lossless PNG encoding, and convenient batch downloads.
| Control | Setting | Effect |
|---|---|---|
| Batch size | Up to 20 files | Converts multiple HEIC photos sequentially to control browser memory use |
| File limit | 25 MB each | Supports typical iPhone HEIC images while preventing excessive local memory use |
| PNG quality | Lossless | PNG encoding does not use a quality slider or add lossy compression |
| Image dimensions | Original pixel size | Keeps the decoded width and height instead of resizing the photo |
| Privacy | Local browser processing | Selected HEIC files are not sent to a conversion server |
| Batch download | Individual PNG or ZIP | Saves one result immediately or packages a completed batch |
HEIC vs PNG: quality, size and compatibility
HEIC stores photos efficiently, while PNG favors lossless decoded pixels and broad compatibility. Converting changes the file format, not the original source file.
| Characteristic | Source | Output |
|---|---|---|
| Compression | Efficient HEVC-based image compression | Lossless PNG compression |
| Typical file size | Usually compact for camera photos | Often substantially larger for photographic images |
| Compatibility | Common on Apple devices but inconsistent elsewhere | Supported by browsers, editors and most upload forms |
| Transparency | Supported by some HEIC images | Supported |
| Pixel dimensions | Source width and height | Preserved by this converter |
| Metadata | May contain EXIF, GPS, HDR and auxiliary data | This tool exports visible pixels and does not copy source metadata |
Private HEIC conversion on Windows, Mac and iPhone
A WebAssembly HEIC decoder runs inside the page, so the same workflow works in a modern browser across desktop and mobile devices.
High-quality PNG without another lossy step
The HEIC image is decoded and written with lossless PNG compression. The process preserves decoded pixels but cannot restore detail already removed by HEIC compression.
Secure local processing
HEIC decoding, PNG encoding and ZIP creation happen in the browser. Your photos remain on the device unless you choose to share the downloaded results.
Works on Windows, macOS and mobile
No HEIC extension, desktop software or account is required. A current Chrome, Edge, Firefox or Safari browser can run the converter.
Designed for bulk HEIC conversion
Files are processed sequentially to reduce memory pressure. A failed or unsupported image reports its own error without discarding completed PNG files.
HEIF input is supported too
The file picker accepts both .heic and .heif containers. The output is always a standard .png image with a matching base filename.
Metadata is intentionally removed
The PNG contains rendered pixels rather than EXIF, GPS, camera comments, Live Photo video or the original HDR representation.

HEIC to PNG converter FAQ
How do I convert HEIC to PNG?
Choose one or more HEIC files above, select Convert to PNG, and download each result or the completed batch as a ZIP. The conversion runs locally in your browser.
Is this HEIC to PNG converter free?
Yes. You can convert up to 20 HEIC or HEIF files per batch within the displayed 25 MB per-file limit without creating an account.
Can I batch convert HEIC to PNG?
Yes. Add up to 20 files, convert them in one queue, download individual PNG images, or save two or more completed results in a ZIP archive.
Can I convert HEIC to PNG without losing quality?
The PNG encoder is lossless and preserves the decoded pixel dimensions. It does not add JPEG-style compression, but it cannot recover detail already lost in the original HEIC encoding or preserve the original HDR representation.
Is it secure to convert HEIC to PNG online?
This converter processes files locally with browser code and WebAssembly. Your selected HEIC photos are not uploaded to this site's servers.
How do I convert HEIC to PNG on Windows?
Open this page in a current Windows browser, choose the HEIC files, and select Convert to PNG. You do not need to install the Windows HEIF Image Extensions for this browser-based workflow.
How do I convert HEIC to PNG on a Mac?
Use the same converter in Safari, Chrome or Firefox on macOS. Add one image or a batch, convert locally, and download the PNG results or ZIP archive.
Can I change HEIC to PNG on an iPhone or iPad?
Yes. Open this page in a modern mobile browser, select HEIC photos from Files or the available photo picker, and download the converted PNG files. Large batches may work better in smaller groups on devices with limited memory.
Why is the converted PNG larger than the HEIC file?
HEIC is optimized for compact photographic storage. PNG uses lossless compression, which often produces a much larger file for a detailed camera photo even when the visible dimensions are unchanged.
Does the PNG keep EXIF, GPS or Live Photo data?
No. The converter exports visible image pixels and does not copy EXIF, GPS, camera metadata, auxiliary depth images, animation or Live Photo video data.
Are HEIC and HEIF the same?
HEIF is the container format, while HEIC commonly refers to HEIF images encoded with HEVC. This converter accepts both .heic and .heif file extensions.
Convert HEIC photos to PNG privately
Add an iPhone photo or a complete HEIC batch, keep the original pixel dimensions, and download lossless PNG output without uploading the source files.
