Why Use Placeholder Images
Placeholders reserve the exact space real images will take, so layouts can be built and reviewed before the photos or artwork exist. Labelling each one with its dimensions tells designers and content teams precisely what to supply. Locally generated files also avoid relying on third-party placeholder services that may be slow, change or disappear.
SVG placeholders are only a few hundred bytes and stay sharp at any zoom, which suits prototypes and documentation. PNG is best for flat colours, JPEG for files that must be small at large sizes, and WebP for modern browsers. Remember to replace placeholders, and to give real images meaningful alt text, before going live.
Key Takeaways
- Reserve the space: Exact dimensions prevent layout shifts later.
- SVG is tiny: Ideal for prototypes and docs.
- Swap before launch: Placeholders are for building, not shipping.
