Why use our Image Resizer?
Every platform wants a different image size — a square for Instagram, a wide banner for YouTube, an exact pixel size for a form upload. Our resizer covers the most common targets with one-click presets, plus full manual control when you need an exact width and height.
"Lock aspect ratio" keeps your photo looking natural by scaling width and height together, so faces and objects never look stretched. Turn it off only when you deliberately want a different shape.
Frequently Asked Questions
Will resizing distort my image?
Not if "Lock aspect ratio" stays on — width and height scale together so proportions are preserved. Turn it off only if you intentionally want to stretch or squeeze the image.
Can I resize to an exact Instagram or YouTube size?
Yes. Use the preset dropdown to jump straight to Instagram Square, Instagram Story, YouTube Thumbnail and other common social media sizes.
Does resizing reduce file size too?
Usually, yes — smaller dimensions mean fewer pixels to store, so the file size typically drops as well. For dedicated file-size control, use our Compress Image tool.
Can I make an image bigger than the original?
Yes, you can enter dimensions larger than the original, but enlarging a photo beyond its native resolution can make it look soft or blurry since no new detail is created.
What image formats are supported?
JPG, PNG and WebP. The resized image keeps the same format as the one you uploaded.
