You could combine them into one ZIP file, but that creates a barrier for the recipient who will need to unzip it. For example, if you have created a few different examples of an Instagram advertisement and want to send it to someone for review, you would need to send all the images separately.
The best reason to convert a PNG to a PDF is that you want to include multiple image files within one file that can be viewed on any system. This is one reason why converting between the two formats might be useful. For example, you can upload a PNG to Instagram but you can’t upload a PDF. However, image files can be needed for other reasons. Image files aren’t great for documents because one file can’t have multiple pages. In fact, it will even look the same across operating systems, so a PDF from a MacBook will look the same on a Windows laptop. If you create a PDF on your smartphone, it will look the same on a laptop, and vice versa. The advantage of saving your documents in this format is that PDF files look the same on any screen. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.PDF files are documents that usually contain text, links, and sometimes images. Creating a PDF can involve compressing a file, making it take up less storage space. They can be viewed on almost all devices. PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. It is maintained by the International Organisation for Standardization (ISO). The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. PDF stands for ‘Portable Document Format’ file.
This compression can affect quality, but this loss of quality isn’t noticeable to most users. JPG is a ‘lossy’ format, meaning that it is compressed to save storage space and make it easier to share. JPEG stands for Joint Photographic Experts Group, which is the name of the committee that standardised the format. However, you can usually adjust settings to save into other formats if needed. Many cameras, smartphones, and basic photo or drawing programs will automatically save into JPG format. JPGs are 2D pixel-based ‘raster’ images, which makes them better for photographs or scans, rather than digital illustrations which are often better as ‘vector’ images. JPG is a universal format which can be opened by almost all image-viewing or -editing programs, by web browsers, and by certain other apps, and they’re supported by most devices. JPG, or JPEG, is one of the most widely used digital image formats.
