Recommendation on image formats, size and dimensions.
For the best image formats on AhaSlides, it is recommended to follow these general rules:
The supported image formats are JPEG, PNG and GIF.
The maximum file size is 15 MB.
Images will look best in an aspect ratio that is as similar to your presentation screen ratio as possible, but feel free to try images with other dimensions as well!
The standard ratio for most screens is 16:9 or 4:3. Try a higher resolution in case the picture doesn't look sharp.
