Preparing your images

The right sizes, formats, and quality settings for showing your art online

01. Why image quality matters

When someone finds your exhibition on Plaarts, the first thing they see is your images. A blurry photo or a page that takes ages to load means they scroll past before they see the work.

The good news: getting your images right takes a few minutes, not hours. It's about saving them at the right size and in the right format. Nothing technical, just practical knowledge.

02. What sizes and formats to use

Save as WebP if you can, JPEG if you can't. WebP files are typically 50–80% smaller than JPEG with no visible difference, and every modern browser supports them. For images with text or sharp edges, PNG keeps things crisp.

Use caseDimensionsTarget size

80–85% Sweet spot for artwork

At 80–85% quality, most people can't tell the difference from the original, but the file size drops dramatically. For fine detail work like etchings or dense paintings, try 90%.

03. A free tool I recommend

VERT is free, open-source, and does everything you need. Drag your images in, pick a format, and download the result. Your files never leave your device. Nothing gets uploaded anywhere.
