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 PDF?
A PDF holds many pictures in one file that opens the same everywhere, which is what forms, schools, landlords and offices tend to ask for. Each picture goes on its own page as a JPG, so the PDF stays small.
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 turn iPhone photos into one PDF?
Choose all the photos at once, or drop them in one after another, and press Download the PDF. Each photo becomes one page, in the order shown. Remove one with its cross to leave it out.
Can I put several photos in one PDF?
Yes. Add up to 30 photos and each becomes a page, in the order shown. Choose Letter, A4 or pages the size of the pictures. On a paper size each photo is fitted inside a small margin and the page is turned to match it.
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.
