Q.What are placeholder images used for?
Placeholder images are dummy assets used during web development and design layout prototyping. They help visualize image positions, alignments, and sizes before final graphic designs are ready.

Image Placeholder Generator FAQs
Answers to common queries about dummy placeholders, image encoding formats, and security.
Q.Does this tool upload my sizing inputs or images?
No. Sizing, colors, text styles, and graphics are processed 100% locally in your browser sandbox using HTML5 canvas and SVG parsing. No server uploads are required.
Q.When should I choose SVG over PNG/JPEG?
Vector SVG placeholders are scalable without pixelation, have extremely small file sizes, and can be embedded inline inside HTML markup. PNG/JPEG formats are better for simulating standard photographic image layers.
Q.How does the copy inline URL feature work?
It generates a Base64-encoded Data URL (e.g. data:image/png;base64,...). You can paste this string directly into HTML image tags or CSS backgrounds without needing to upload separate files.
