When to use an image resizer
Use this free image resizer when a website form rejects oversized photos, when you need social-ready dimensions, or when product images must match a listing template. Resizing dimensions is often better than only compressing if the photo itself is much larger than the display size.
After resizing, you can also compress the image to reduce file size, or convert the format for JPG, PNG, or WebP delivery.
Frequently asked questions
Does resizing an image reduce file size?
Often yes, because fewer pixels usually mean a smaller file. For the best size reduction, resize first and then use the Compress Image tool.
Can I keep the original aspect ratio?
Yes. Keep aspect ratio enabled and change either width or height. The other value updates automatically to avoid stretching.
Will my photo be uploaded?
No. This resize tool processes the image in your browser and does not upload it to the server.
