What is a HEIC file?

HEIC is the format iPhones and iPads save photos in. It holds the same photo in about half the space of a JPG, but Windows, Android, many websites and most print shops cannot open it.

Apple chose it because it keeps a photo at the same quality in half the space, and it can hold extras such as the depth of a Portrait photo and the moving part of a Live Photo. The converter keeps the still photo.

Why PNG?

A PNG keeps every pixel exactly, so it loses no more detail however often it is edited and saved, and it keeps transparency. Print-on-demand suppliers such as Printful ask for PNG print files for that reason.

Nothing is uploaded

Converters that upload your photos keep a copy on someone else’s server, at least for a while. This one does the work in your browser, on your own device, so private photos stay private. The pictures are also saved fresh, so the camera details and GPS position phones write into every photo are not copied into the new files.

Printing the photo

A 12 MP iPhone photo (4032 × 3024 pixels) prints sharp up to about 13 × 10 inches at 300 DPI, and about twice that as a poster seen from a step back. The print size calculator works it out for any picture. Then put it on a poster or a mug.

How do I convert HEIC to PNG?

What is a HEIC file?

HEIC is the format iPhones and iPads save photos in. It holds the same photo in about half the space of a JPG, but Windows, Android, many websites and most print shops cannot open it.

Should I choose PNG or JPG for an iPhone photo?

JPG, for most photos: it is a fraction of the size and looks the same. Choose PNG when the photo will be edited and saved several times, or when it is a screenshot or a graphic with sharp edges and flat colors.

Will the PNG be larger than the original?

Usually, yes. PNG keeps every pixel without loss, so a photo can come out three to five times larger than as a JPG or WEBP. Nothing is lost on the way to PNG, and a transparent background stays transparent.

Are my files uploaded?

No. The converter runs in your browser: files are opened and saved on your own device and never sent to SlapMake or anyone else. Browsers other than Safari cannot open HEIC themselves, so the first time a HEIC decoder (libheif) is loaded from slapmake.com.

How many files can I convert at once?

Up to 30 at a time, each up to 50 MB and 100 megapixels. Camera data and GPS position are not copied into the new files. A picture larger than a phone browser can hold is made as large as it allows, and the page says so.
