Presentation tools
Inspect size changes and formatting details before you edit. Try either tool with its built-in example.
Compare two versions and find which package parts account for the increase. You can also inspect one presentation.
Path-based comparison. No visual rendering or full payload validation.
See slide counts, explicitly declared font families and sizes, and empty text placeholders.
Inherited styling and visual appearance are not evaluated.
Your presentations stay in your browser. The tool code does not upload the files you choose. Website hosting is separate; see privacy details.
