Frequently Asked Questions

What is heictopng.io?

heictopng.io is a free online tool that converts HEIC and HEIF image files to PNG quickly and directly in your browser.

Is heictopng.io really free?

Yes. There are no hidden fees, watermarks, or sign-up requirements. Convert as many batches of files as you need, whenever you need to.

Do I need to create an account?

No. heictopng.io works with zero sign-up. Just open the site and start converting.

Do you upload my photos to a server?

No. Image files are processed locally in your browser and are not uploaded for conversion.

Will converting HEIC to PNG lose image quality?

Lossless mode preserves decoded pixel quality and the selected dimensions, but the PNG output can be larger than the source HEIC or HEIF file. Smaller-file mode reduces the color palette and may slightly reduce color detail.

How many files can I convert at once?

You can convert up to 10 files per batch, with a maximum file size of 50 MB per file and a 150 MB total batch limit.

Does heictopng.io work on Windows?

Yes. Since it runs entirely in your browser, heictopng.io works on Windows, Mac, Linux, Chromebook, and mobile devices, with no software installation required.

Why can’t Windows open my iPhone photos?

iPhones save photos in Apple’s HEIC/HEIF format by default, which is not natively supported by many versions of Windows Photo Viewer without additional codecs. Converting them to PNG makes them broadly viewable without extra software.

Does the converted PNG keep my photo’s metadata (EXIF data)?

No. The current converter focuses on image conversion and does not copy EXIF metadata such as the date taken, GPS location, or camera information to the PNG.

Can I use heictopng.io with Adobe Lightroom?

Yes. Converting files to PNG first can make importing and editing more consistent in Lightroom or other editing software with limited HEIC support.

Should I convert HEIC to PNG or JPG?

It depends on your use case:

• PNG is best when you need lossless quality, transparency support, or plan to edit the image further.
• JPG is best for smaller file sizes and everyday sharing where slight compression is acceptable.

If you are not sure, PNG is the safer choice for preserving image quality.

How do I stop my iPhone from saving photos as HEIC?

On your iPhone, go to Settings > Camera > Formats and select “Most Compatible” instead of “High Efficiency.” New photos will be saved as JPG, but existing photos will not be converted.

Is there a mobile app?

Not currently. heictopng.io works directly in your mobile browser, so there is no app to download.
