Frequently Asked Questions
How do I resize an image without stretching it?
Check the "Lock aspect ratio" box in our Image Resizer. When you change the width, the height automatically adjusts to maintain the correct proportions. Your image will never look stretched.
What is the best image size for social media?
Instagram: 1080×1080px (square) or 1080×1350px (portrait). Twitter: 1200×675px. Facebook: 1200×630px. LinkedIn: 1200×627px. Use our resizer to hit these exact dimensions.
Can I resize images in bulk?
Currently our resizer handles one image at a time. For bulk operations, resize your first image, note the settings, and process the rest individually — each takes just seconds.
Does resizing reduce image quality?
Reducing dimensions (downscaling) maintains quality well. Enlarging images (upscaling) will make them look blurry or pixelated. For best results, always start with the largest version of your image.
