I have configured "Save As Preferences" and have set them so Snagit Editor always saves images as .jpg.
The problem is that when I do not save the image, but rather copy the image from Snagit Editor (using the Copy All button) and then paste it into an email, the image format is always .png.
Can this be changed?
You want to find the Share properties for Clipboard. In SnagIt 11 this is under the Share tab in the SnagIt Editor.
Click the double-ended arrows to the right of the word Outputs. This should open the Share Properties window.
Within the Image File tab, select Always Use this file format and select JPG. Then click Apply and Ok.
When I tried pasting into a new email using Microsoft Outlook, I don't really know what format that image is in other than if I right-click on it and pick "Save as picture..". The file type in the save dialog shows PNG, but that's Outlook deciding on that format.
How are you seeing that it is PNG?
The user who reported this was pasting images into an online task management program which would occasionally return errors about the png image.
I had to find an online tool that would tell me what format the copy/paste image was because I couldn't tell either, and found this site which tells me whether I am pasting a jpg or png file: https://codepen.io/netsi1964/pen/IoJbg
