Frequently asked questions
- Do I get free credits to try Change PowerPoint Slide Size?
- Yes — new accounts get 3 free credits to spend on any tool, Change PowerPoint Slide Size included. After that you only pay for what you run.
- How many credits does Change PowerPoint Slide Size cost?
- Everything runs in your browser and nothing is uploaded: free accounts pay 1 credit per run, and Pro or Pro+ members run it as often as they like.
- Is the content I paste private?
