What if my images are too big for upload into NewZapp?

            The maximum physical file size for an image to be uploaded into your NewZapp images library is 1MB. The primary reason for this is to help safeguard you against including images in your campaign which might be slow to download on the recipient's screen or device. If you are are on a fast broadband connection you might not be aware of the limits that other people might have, especially on a mobile device. Waiting for your image to download could be annoying and prompt the recipient to delete your email or unsubscribe from further comms.

            So whilst the system allows you to upload an image of up to 1MB, the smaller the file size of your image the better!

            NewZapp checks your images are within maximum file size limits as you upload them into your images library.
            If your are seeing a message on screen that upload has failed then either:
            1. Your image is larger than 15MB which means it fails the first upload check, or
               
            2. Your image was smaller than 15MB but even after the system optimised it during the upload process, it was still over 1MB which means it fails the second upload check.
            Should your image fail to upload then this article is to help you rectify the problem.

            What does 1MB mean?
            This means that a file is 1000 kilobytes in size.
            Kilobytes are also sometimes shown in capitals as KB (e.g. 1000KB) or as 1MiB.
            1000 kilobytes = 1 MB, or 1 MiB, or 1 megabyte.

            When viewing files in File Explorer you will usually see image sizes shown in KB:


            Why is my image so large?

            Most organisations use images as part of their marketing work and when these are purchased, the provider of the image is likely to supply it in a high resolution so that you can use the image for a variety of large scale purposes such as posters or display material. You don't need such a large format when using images for digital means, such as on a website or within an email.  

            Is 1000kb the same as 1000 pixels?
            No. Pixels are a different kind of measurement. Every image is made up of a grid of pixels, the more pixels the image is made up of, the bigger it appears on screen. As a rough guide, the majority of emails are between 600 and 700 pixels wide.  

            How to I make my image smaller?
            If you open your image at 100% (actual) size you will see that it's much larger than you require for your email, so the image needs to be compressed before you use it in your email. NewZapp includes a compression process as it uploads your images, but if your image is too marge for NewZapp to accept, here are a couple of options we can suggest:

            1. Your own default image editor
            When you open an image to view or edit it, your PC or laptop will use a default program such as Windows Photo Viewer, or Paint. Within this program you  will be looking for tools to edit / resize.

            As we don't know how big your own images are, it will be safest to advise you on how to reduce it's pixel dimensions, as that in turn will make your image a smaller file size. As a bench mark, we'd suggest you reduce your image down to a size that is not more than 700 pixels wide or tall, and always keep the "Maintain aspect ratio" option ticked (which prevents your image from being distorted as it's reduced in size).

            2. A third party site 
            One of our favourites is a free to use site called tinypng.com. On this site a very clever little panda compresses images by optimising them. The end result is a smaller more compact image that should be much more flexible for use in digital work, such as on a website or in NewZapp emails. The site can optimise jpeg and png file formats, both of which are compatible with your NewZapp account.

            TinyPNG doesn't ask you to specify the size you want your image to be, it will just use it's own judgement on the maximum compression that can be used to maintain image quality.

            After you have dropped an image onto the TinyPNG dropzone, compression takes place and you will see the new file size of your image. If you've reached your target then you can click to download the image to your own 'Downloads' folder ready for upload into NewZapp.

            It's worth noting here that if your image is very large (eg. tens of MB in size) then this process might not give you an image that is small enough in one step, and you may need to save the image and then run through the process a second time.

            Is 1MB the idea image file size to aim for?
            Well, to be honest, not really. Don't forget that the smaller the kb file size the quicker the image will load on screen. Most images can be perfectly crisp and sharp at 50kb.

            And what about image file format?
            NewZapp's drag and drop editor allows the upload of JPG, GIF (including animated gifs) and PNG image files. View the complete How to... Images user guide for more information.

            How will I know if, after all this, my image is the right pixel size for my email campaign?
            The good news is that once an image has been uploaded into your NewZapp account, the drag & drop editor will reduce the image down in size again if the block that you drop your image onto doesn't need an image that's as large as the original. You'll see it snap down on screen as you drop it, for a perfect fit.
