Convert HEIC to PDF online, for free.
High Efficiency Image Codec (HEIC) is a variant of HEIF that Apple adopted in 2017 when iOS 11 was introduced. The main advantage of HEIC is that it requires less space than JPEG (JPG) with no diminishment of image quality. Both HEIC and HEIF are based on High Efficiency Video Coding (HEVC).
HEIC opens by default on Apple iOS and related applications and operating systems, such as macOS, iOS 11, macOS High Sierra, Apple Photos, and Apple Preview. Android OS also supports HEIC. On Microsoft Windows, open HEIC with Zoner Photo Studio.
The best alternative program for opening HEIC is XnView MP, which works across platforms.

The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today. The reason PDF is so widely popular is that it can preserve original document formatting. PDF files always look identical on any device or operating system.
Most people head right to Adobe Acrobat Reader when they need to open a PDF. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use.
Most web browsers, like both Chrome and Firefox, can open PDFs themselves. You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. I highly recommend SumatraPDF or MuPDF if you're after something a bit more. Both are free.
