Re-sizes images right inside the browser BEFORE uploading them.
As of April 2026, Canvas Image Resize is a WordPress image plugin with 1.0K+ active installations and a 4.6/5 rating from 10 reviews. It has been downloaded 13K+ times in total. Requires WordPress 3.3.2+ and PHP false+. Available on WordPress.org since 2016. Downloads are down 18% this week. Top alternative: Firelight Lightbox.
If you host your site in a poor environment, WordPress may fail uploading large images as the process of creating the different sizes and thumbnails takes a large amount of CPU usage.
With this Plugin the images are simply resized to a maximum dimension (of for example 1600 x 1600 pixels) right in your browser before uploading them.
The nice side effect is that unnecessary big images are resized to a fine size to still provide a usable, qualitative image.
