Features

📱

iPhone Photos Welcome

Convert the HEIC files your iPhone and iPad create by default into PNG files that work everywhere.

🖼️

Lossless Quality

PNG preserves every pixel of detail from the decoded image with zero compression artifacts.

🔲

Transparency Support

Unlike JPG, PNG carries full alpha-channel transparency — useful for edited or composited images.

🔒

Private by Default

A WebAssembly decoder works in your browser. Your photos are never uploaded or seen by any server.

How to Use the HEIC to PNG Converter

  1. Drag and drop a HEIC or HEIF photo into the upload area, or click browse files to select one from your device.
  2. Wait a moment while the decoder runs. The first conversion loads a small decoder library, so it can take a few extra seconds on the first use.
  3. Watch the preview appear and check the file-size stats — the PNG will typically be larger than the HEIC since it is lossless.
  4. Click Download PNG to save the converted file, or click Reset to start over with another photo.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

HEIC photos often contain private details — locations, faces, and personal moments. Most online converters ask you to upload the file before processing, which puts that data at risk. TinyToolzz takes a different approach: a WebAssembly HEIC decoder runs entirely on your device.

The preview and the final PNG are both produced in your browser memory. Nothing is sent over the network, stored, logged, or shared. When you leave the page or click Reset, the image data is released from memory, and the original HEIC on your device is never modified.

Frequently Asked Questions

What is a HEIC file?
HEIC (High Efficiency Image Coding) is the default photo format on modern iPhones and iPads. It compresses photos more efficiently than JPG, so files stay smaller. The trade-off is compatibility: many Windows apps, older phones, and some websites cannot open HEIC files.
Why should I convert HEIC to PNG instead of JPG?
PNG is a lossless format, so converting HEIC to PNG preserves every bit of detail from the decoded image without any additional compression artifacts. PNG also supports full alpha-channel transparency, which matters if your HEIC source contains transparent elements. JPG is lossy and discards detail on every save. Choose PNG when quality matters more than file size.
Will the PNG be larger than the HEIC?
Almost always, yes. HEIC uses modern compression that is significantly more efficient than PNG. A converted PNG is typically 2–5 times larger than the original HEIC. If file size is a concern, consider the HEIC to JPG converter instead, which produces smaller files at the cost of lossy compression.
Does converting HEIC to PNG preserve transparency?
Yes. Unlike JPG, PNG supports an alpha channel, so any transparent pixels in the decoded HEIC are carried through to the PNG output. However, most standard iPhone photos are fully opaque, so transparency only applies in rare cases such as edited or composited images.
Does the converter keep my photo metadata?
No. Photo metadata such as GPS location, camera settings, and capture time is not copied to the output PNG. If you need to keep that metadata, make a copy of the original HEIC before converting, because the PNG is a separate file and the original remains untouched on your device.
Are my HEIC files uploaded to a server when I convert them?
No. The HEIC to PNG tool runs entirely in your browser. A WebAssembly decoder turns your photo into a PNG locally on your device, and the file is never transmitted, stored, or recorded on any remote server.
