When developing websites you might not always have real content to use in the building stage. That`s why web designers and developers often use placeholders to help with the design process. Placeholders give designers an idea of how their client`s website will look before the final content is available. So in this post we`ve put together 21 Useful Image, Text & Data Placeholders to help you visualize how a website or an app will look even though the actual content is not yet available.

JSONPlaceholder

It is an online REST service that you can use whenever you need some fake data. Run this code in a console or from anywhere that CORS and JSONP is supported. It’s like an image placeholder but for web developers and is used for tutorials, faking a server, sharing code examples and more.

Data Populator

A plugin for Sketch and Adobe XD CC to populate your design mockups with meaningful data. Goodbye Lorem Ipsum. Hello JSON.

Mocka

It is a very simple content placeholder that you can use for your website or web application, while loading your page’s content. It weighs very little (about 500 bytes minified and gzipped), is fully customizable and you can easily include it in your project’s CSS file, by using the Sass mixin provided. Alternatively, you can copy its code and inline it in your HTML for even faster loading.

Holder.js

Holder renders image placeholders entirely in browser. Placeholders can have custom colors, fonts, resizing behavior, and rendering engine (Canvas/SVG).

Fakeimg

When designing websites, you may not have the images you need at first. But you already know the sizes and inserting some placeholders can help you better seeing the layout. Don’t waste your time making dummy images for your mockup or wireframe. Fakeimg.pl is a little tool that generates images with an URL. Choose the size, the colors, even the text. It’s free and open-source.
