Image Resizer — Frequently Asked Questions
Does resizing an image reduce quality?
Downsizing an image slightly reduces detail since pixels are reduced. However, the visual quality remains excellent at normal viewing sizes. Upsizing may show some softness. For best quality, avoid resizing more than 200%.
What does "Maintain aspect ratio" do?
When enabled, changing the width automatically adjusts the height proportionally (and vice versa), preventing your image from looking stretched or squished. Disable it if you need an exact non-proportional size.
What's the maximum image size I can resize?
Since all processing happens in your browser, the limit depends on your device's memory. Most modern devices can process images up to 50–100MB without issues. Output dimensions can be up to 10,000 pixels.
