Canva is one of the most popular design tools on the web, used by millions for social media graphics, presentations, and marketing materials. Its image resizing capability is part of a much larger platform — which is both its strength and its limitation when all you need is to resize an image file.
Kordu's Image Resizer is built for exactly one job: take an image, set the dimensions, download the result. No account, no project canvas, no design workflow to navigate. Everything runs in your browser — nothing is uploaded to a server.
If you're already using Canva for design work, its resize tools fit naturally into that workflow. But if you just need to resize a photo or image file quickly and privately, Kordu is significantly faster and requires no signup.

Our verdict
Bottom line
For quick, private image resizing without an account, Kordu wins. It's purpose-built, browser-based, and zero-friction. Canva requires signup and frames resizing inside a full design tool — powerful, but overkill if you just need smaller dimensions on a file. Choose Canva if you already use it for design work or need extensive format options; choose Kordu for fast, private resizing with no overhead.
