Image Resizing Guide
How Resizing Affects Image Quality
- Upscaling images (making them larger) can result in blurriness and pixelation
- Downscaling (making them smaller) generally preserves quality but can cause slight softening
- Always keep originals when working with important images
- For best results, resize images in increments rather than extreme changes
Resizing an image for a website, a form upload limit, or an email attachment usually means opening an editor just for one change. This tool resizes an image to exact dimensions directly in your browser, with no software and no upload.
Common ways to resize images
Resize image to specific size
Enter an exact width and height in pixels when a website, passport form or job portal asks for a fixed size.
Change image dimensions online
Keep the aspect ratio locked to resize an image online without stretching or squashing it.

Frequently asked questions
Will resizing make my image blurry?
Making an image smaller keeps it sharp. Making it much larger than the original can make it look soft, because new pixels have to be filled in.
What does lock aspect ratio mean?
It keeps the width and height in the same proportion, so the image is not stretched or squashed when you change one of them.
Which size should I use for a passport or visa photo?
Check the exact pixel size the form asks for, enter it here, and resize. If there is also a file size limit, use our Image Compressor afterwards.
Are my images uploaded?
No. Resizing happens in your browser and the image stays on your device.
