Extend Canvas / Add Padding — Solid or Transparent Border
Add solid or transparent padding around an image: Polaroid white borders, fill out a target ratio, or give an icon breathing room. Set all sides uniformly or each side separately. Works on desktop, tablet & mobile — batch, local, no upload.
Extending the canvas adds a solid or transparent margin around the original image — it enlarges the canvas without changing the image itself (a geometric operation, not AI outpainting). Common for Polaroid-style borders, giving logos / product shots whitespace, or padding an image to a larger size. Set all four sides uniformly or top / right / bottom / left separately, with a solid or transparent fill. Processing runs entirely in your browser — no upload.

Extend Canvas FAQ
No. This tool adds geometric padding (solid / transparent margins) and does not generate content. True AI outpainting needs a server-side model, which conflicts with this sites local, no-upload approach — so we dont do it.
JPG has no alpha channel, so transparent automatically switches to a white fill. Save as PNG or WebP to keep transparency.
Yes — turn off "uniform on all sides" to set top / right / bottom / left separately.
No. Extending the canvas runs entirely in your browser.
