Generate customized dummy image placeholders, tweak ratios, and grab instant Base64 Data URL or SVG markup completely locally in your browser.
100% Secure Client-Side Placeholder Engine
This generator is built entirely inside your browser memory sandbox. It utilizes standard HTML5 Canvas and SVG rendering APIs to compile image assets completely locally.
No uploaded files, sizing dimensions, or configurations ever touch our servers. Your data and layout structures remain strictly private on your computer.
Download your placeholder images instantly as PNG, JPEG, or clean vector SVG files.
Choose from pre-selected professional gradients or customize solid backgrounds using an interactive picker.
The placeholder text size dynamically adjusts to fit your target width/height boundaries, or customize it manually.
Frequently Asked Questions
Explore comprehensive answers, technical specifications, and helpful guidance for processing your documents.
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.
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.
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.
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.
