Expand Canvas Free Online: Add Margin or Square Background
Expand photo canvas into square, portrait, or widescreen layouts without cropping the original image, using blur, solid, or transparent padding.
Expand Canvas is useful when a platform needs a different aspect ratio than the photo you already have. Instead of cutting off content, you can keep the original image fully visible and build the extra frame space around it for social posts, ads, thumbnails, and catalog layouts.
How to Use It
- Upload your image and wait for the local preview to load.
- Adjust the settings: Pick a target layout like square, 4:5, 16:9, or custom size, then choose anchor position and padding fill style.
- Download the result: Download the processed file directly to your device.
Controls and Options
Choose the target aspect ratio first, then pick an anchor and fill style so the original image stays balanced inside the new frame.
Formats and Output
Supports JPG, PNG, and WebP. Transparent padding is best exported as PNG, while blur or solid backgrounds can be saved as PNG, JPG, or WebP.
Frequently Asked Questions
Does Expand Canvas crop the original image?
No. The tool keeps the full image visible and only adds space around it to fit the new layout.
When should I use blurred padding?
Blurred padding works well for social content and thumbnails because it fills the new frame without introducing harsh empty borders.
Can I make a square post from a landscape image?
Yes. Choose the Square preset and Pixlane will add padding instead of cropping the landscape photo.
Is Expand Canvas free to use?
Yes. Expand Canvas is free, browser-based, and private.
Are my files stored on a server?

How long does processing take?
