Images by Edmund review
If I’m putting six screenshots into an article, I want them to load quickly and still be readable on a phone. Images by Edmund is a free Mac app that can resize a batch and export it to WebP from one window. It requires an Apple silicon Mac with macOS 15 or later.
Make web copies in a separate folder
After taking the screenshots with CleanShot X, I’d drag their PNGs into Images by Edmund, choose WebP and enter the width the article needs. Pick a separate folder at export so the original captures are still handy when a screenshot needs replacing.
Check the smallest text before publishing
The app shows the output size before you save. I’d compare the files and open a couple of exports against the article’s actual background, especially if they have transparent edges. If a particular WebP is larger or makes a tiny menu label harder to read, I’d keep that one as a PNG.
Anabel’s take
I’d use this when an article has a whole set of screenshots. I’d decide what to keep by opening the page on my phone, where the words and thin lines in the pictures are usually hardest to see.
