Finally a thumbnail editor that works natively in Safari without downloading anything. Drag and drop from Finder, Command+Z to undo. Feels like a real Mac app.

My MacBook only has 128GB storage. Can't install another big app. This runs in Chrome and takes zero storage. Perfect for creators with limited space.

I switch between my iMac at home and MacBook on the road. Same tool, same projects, nothing to sync. Browser-based is the way.

Was using Photoshop but it's slow on my older Intel Mac. This loads instantly and the AI features work great. Actually prefer it now.

Tips for Making Great Thumbnails
Use Chrome or Safari for best performance. Both work great on Mac and support all features.
Drag images directly from Finder into the editor. Faster than clicking the upload button.
Learn the keyboard shortcuts. Command+Z, Command+S, Command+C save significant time.
Export to a dedicated thumbnails folder in Finder. Keep your work organized.
Use the mobile preview feature. Most viewers watch on phones, not Macs.
Common Mistakes
What to Avoid
Downloading unnecessary Mac apps when the browser version has all the features you need.
Using outdated Safari or Chrome versions. Update your browser for best performance.
Forgetting to allow file downloads in Safari settings if exports fail.
Not using Command shortcuts. They make editing much faster than clicking.
