Frequently Asked Questions — Dummy Image Generator
What file formats are supported for generating placeholder images?
Zip Safari supports PNG, JPG, and WebP formats. We recommend using PNG if you plan to style layouts requiring transparency, or JPG/WebP for optimized lightweight previews.
What is the maximum layout dimension I can generate?
Our online generator supports canvas dimensions from 1x1 pixels up to a maximum of 4000x4000 pixels, meeting the demands of standard high-density wireframes and mockups.
Can I customize the font style and size of the text?
Yes. You can select font size scales ranging from Small (24px) up to Huge (96px), and specify any hex colors for the background canvas and the center text labels.
