Frequently Asked Questions
Does this image resizer upload my file to a server?
No. Every resize happens locally in your browser using the Canvas API, so your image stays on your device.
What is the best format for resized images?
JPEG is usually best for photos because it keeps file sizes small. PNG is better for graphics, screenshots, and transparent images. WebP often gives smaller files than JPEG with similar quality.
Will resizing an image reduce quality?
Shrinking an image usually looks fine, but enlarging it can make it softer or blurrier because new pixels have to be generated. Lower export quality settings can also reduce file size at the cost of detail.
How do I keep the original aspect ratio?
Turn on the maintain aspect ratio option when using custom dimensions. Changing the width will automatically update the height, and vice versa.
