Frequently Asked Questions
What image formats can I resize?
Our image resizer supports all common image formats including JPEG, PNG, WebP, and GIF. The output format will match your original image format to preserve quality.
Will resizing reduce image quality?
When reducing image size, quality is generally well-preserved. When enlarging images, some quality loss may occur as the tool needs to interpolate new pixels. We use high-quality image smoothing for the best results.
What does 'maintain aspect ratio' mean?
Aspect ratio is the proportional relationship between width and height. When enabled, changing one dimension automatically adjusts the other to prevent image distortion.
Is there a maximum size limit?
The tool can handle most image sizes, but very large images may take longer to process. For best performance, we recommend images under 10MB.
Are my images uploaded to a server?
No, all image processing happens directly in your browser. Your images never leave your device, ensuring complete privacy and faster processing.
