What is a Placeholder Image Generator?
Mockups need images at the right dimensions before real assets exist. Placeholder services work: until you are offline, or the service rate-limits, or the client sees a third-party URL.
This generates the image on a local canvas: any size up to 4000px, your colors, optional label, downloaded as a PNG you own.
Frequently asked questions
Why not just hotlink a placeholder service?
Local files never break in demos, work offline, and keep client mockups free of third-party calls.
What is the size limit?
8-4000px per side: beyond that, canvases get memory-hungry for no mockup benefit.
Can I use these in production?
They are plain PNGs: use them anywhere, though presumably as temporary stand-ins.
SVG output?
PNG only for now; PNGs drop into every design tool without compatibility questions.
