There is some confusion here between resizing the image and decreasing the data file size. Email sees an image as data, and generally what it is saying is that there is too much data to be transmitted. That problem may be solved by compressing the data further, but compression does not change the image size. When a compressed image file is unpacked it should be the same size as it was prior to compression, but has lost some detail/information that was in the original. If you have ever received an image in email that requires you to scroll around because some of the image is "off screen" you have seen this in action. While some software automatically resizes the image to fit the screen, that cannot be relied upon, and it introduces additional artefacts over which you have no control. The good news is that that screen specific resizing does not usually have any effect on the image file itself, just the altered copy that is sent to the screen.

You should probably consider what use the recipient is going to be able to make of the image file at his end. If it will only be displayed on a phone screen, you do not need as big an image as if it is to be shown on a high resolution computer monitor. The best way to resize without losing control of the process is to use a photo editor that allows you to resize to a specific pixel height and width, and match that to the expected display the recipient will use. If you want to gamble on on the fly resizing at the recipient's end, then you should resize to the maximum number of pixels your file is likely to encounter. An image at 1080 x 1920 pixels will generally fill most screens with minimal adjustment, although it may get stretched a bit (with interpolation artefacts) to fill a high res monitor. If an image that size is too many MB for the transfer, then you can use a higher level of compression to shrink the file. If your recipient needs to do something other than look at your image, then you may need to send a larger file by another method like online file sharing sites.

An easy option is to upload your photo or photos to wetransfer.com. Go to the site, put in your email, your recipients email, a title, and a message. You can send up to 2GB of files free. Wetransfer will let you know when it is uploaded and sent, and when it is downloaded by the recipient. They have a week to download it.

Thanks so much for this tip.

It depends if one needs (wants) to send the original file size or just a reduced file size copy that will fit in an email, like for viewing on a computer, tablet, etc.. It depends on the purpose/requirement of the "send".

Examples and discussion of why using 2048-pixels on the 'wide side' of your image is your best bet, no matter what software is used to make this change:

Use WeTransfer. Do not have to resize.

The Fastone Photo Viewer also has “resizing.” Both programs are free and intuitive.

I was having same problem then I noticed a screen in composing the email if I wanted to rezize the pictures, offers 3 sizes, the smaller two work well. Pay attention to screens in your email.

I usually use links from Dropbox, and We Transfer is great, but when I use my Gmail, it switches large attachments to Google Drive and retains the original size.

Use a service like Drop Box.

Email is concerned with file size not image size or file type. There is no need to change the image size, i.e. pixel dimenisions.

The simpliest way is to use any photo editor, such as Windows Photo, Apple Photo or any other photo editor you may have. Open your jpg image and then immediately save (or export) it, but be sure to increase your file compression before exporting. Increasing your file compression will reduce your file size without reducing image size.

Increasing compression will degrade the image, but not to a degree that is noticeable to the viewer.
