Resize Images Online
Scale the artwork, then place it on a target canvas instead of stretching the subject. PNG, JPG and WebP are accepted; export PNG, JPG, WebP or GIF.
What this tool does
Stores often require a fixed frame such as 1200×1200, while source photos are rarely square. Separate image size and canvas size so the subject can stay proportional and sit centered with clean margins.
This is not a cropper. It scales and places the image. If you must cut the edges, compose that crop first, then use this page to export a consistent frame.
The default canvas is 1200×1200 and can be changed. Process multiple files and choose the output format required by the destination.
The tool is free. Keep the unresized original and treat the result as a delivery copy.
Use cases
- Product photos placed on a square catalog canvas
- App icons exported to a fixed pixel box
- Social frames prepared to a required width and height
- Design handoff with one shared canvas size
How it works
- Select PNG, JPG or WebP images.
- Set image size and canvas size separately.
- Choose an output format and convert.
- Check centering and proportion, then download.
Frequently asked questions
What is the difference between image size and canvas size?
Image size is the scaled artwork. Canvas size is the final file frame. If they differ, the image is centered.
Will it stretch the subject?
The artwork is scaled to the image width and height you enter. To keep proportion, match those values to the source ratio and let the canvas fill the required frame.
Is this a cropper?
No. It resizes and places images. There is no freeform crop tool on this site.
Which formats are supported?
Input: PNG, JPG, WebP. Output: PNG, JPG, WebP or GIF.
Can I resize a batch?
Yes. Select multiple files and download a ZIP.
