The idea for Aspectr came during a client call that made me think: this is insane.
They described their workflow how they create ad assets:
- Brand team creates a hero image with 10MB
- my client sends it to an agency via email
- the agency resizes it for each platform and bills by the hour
- agency sends it back days later
- my client sends the resized assets to the next agency
- they upload assets into ad manager.
Repeat for every campaign. Every creative refresh. Everytime somebody forgets something.
In 2025, this should not exist. So I built Aspectr.
I built it with Claude & Claude Code. Here is how we split the work:
- I think: requirements, decisions, quality standards and questions until I am satisfied.
- Claude plans: system design, mockups and blunt feedback.
- Claude Code builds: code, debugging and shipping.
It took me around 60 hours which became 180 ad formats across 20 platforms.
There is a free trial if you want to try it. You find a short video walkthrough on the homepage that shows how it works and also links to help section.
I am curious:
If you have dealt with ad asset resizing before, Photoshop or other tools:
- Does this sound familiar?
- What worked?
- What frustrated you?
And if you try Aspectr:
- What could I improve?
- What did I miss?
If you like Aspectr, I´d like to hear that, too. :-)
