❓ Frequently Asked Questions (FAQ)

How does image resizing work?
Image resizing changes pixel dimensions by resampling - adding or removing pixels while maintaining visual quality using interpolation algorithms.
Will resizing reduce image quality?
Downsizing (making smaller) maintains quality well. Upsizing (making larger) can reduce quality and cause pixelation. Always start with high-resolution originals.
Are my images uploaded to a server?
No! All resizing happens in your browser. Your images never leave your device, ensuring complete privacy.
What's aspect ratio and why maintain it?
Aspect ratio is the proportional relationship between width and height. Maintaining it prevents distortion and stretching of your images.
Can I resize multiple images at once?
Yes! Our tool supports batch processing. Upload multiple images and resize them all to the same dimensions.
What image formats are supported?
We support JPG/JPEG, PNG, and WebP formats - the most common image types used on the web and social media.
Should I resize before or after editing?
Edit first, resize last. Work with full-resolution images during editing, then resize to final dimensions as the last step.
Can I resize images on my phone?
Yes! The image resizer works perfectly on smartphones and tablets. Resize images anywhere.
What's the difference between resizing and cropping?
Resizing changes dimensions by scaling the entire image. Cropping removes portions to change dimensions. Both are useful for different purposes.
How do I know what size to use?
Check the platform's recommended dimensions. We provide common presets for social media, websites, and other uses.
