Free image resizer

Resize a photo to any size in pixels, then download it as JPG, PNG or WebP. Everything happens in your browser, so your photo is never uploaded.

Resize images automatically with a URL

Resizing one photo by hand is fine. Resizing a whole catalogue is not. With Frametile you do the same thing by editing the image's address, and every size is created on request:

https://frametile.com/api/YOUR_API_KEY/images/folder/photo/w_600,h_400,c_scale

Your settings above would look like this: w_600,h_400,c_scale,f_jpg,q_80

Common questions

How do I resize an image online?

Choose a photo, enter the width and height you want in pixels, pick a format and press Resize. Then download the result.

Is my photo uploaded anywhere?

No. The photo is resized by your browser and never leaves your device.

Does it keep the aspect ratio?

Yes, by default. Change the width and the height follows, so the picture is not stretched. Untick the box to set both sizes yourself.

Which format should I choose?

Use WebP or JPG for photos, and PNG for graphics or anything that needs a transparent background.
