Quick answer

To add a border to an image online: go to pixeltools.io/beautify, upload your photo, then use the Canvas panel to set a background color or gradient and increase the padding around the image — that padding is your border. Adjust the corner roundness if you want soft edges instead of a sharp rectangle, then export as PNG or JPG. Nothing is uploaded to a server; the image is processed in your browser.

What 'adding a border' actually means

A photo border is extra space around the edges of an image, usually filled with a solid color, gradient, or pattern, so the photo reads as framed rather than edge-to-edge. This is different from a frame overlay drawn on top of the image (which crops into the photo) — a proper border adds new canvas around the original photo without cutting anything out. PixelTools' beautifier does this by placing your image on a larger canvas and letting you control the background and the padding (the border thickness) around it.

Solid color vs. gradient borders: which to pick

A solid white or black border is the classic choice — it works with any subject, matches a Polaroid or print-frame look, and doesn't compete with the photo's colors. Use white for a clean, minimal look or black for a bolder, high-contrast frame. A gradient border adds visual interest and works well for social media posts or promotional images where you want the frame itself to catch attention. Match the gradient's tone to your photo's palette (warm gradient for warm photos, cool gradient for cool ones) so the border complements rather than clashes.

How much padding should a border have?

For a subtle border, keep padding small relative to the image — just enough to separate the photo from whatever background it's placed on next (a website, a slide, a social feed). For a print-style or Polaroid look, use a thicker, often uneven border (more padding on the bottom than the sides/top). There's no single correct number: increase the padding until the framed image looks balanced at the size you'll actually display it, then export and check it at that size before finalizing.

Rounded corners vs. sharp corners

Sharp rectangular corners give a classic, print-like border and are the safer default for professional or portfolio use. Rounded corners give a softer, more modern look that tends to work better for app screenshots, UI mockups, or casual social posts. If you're bordering a screenshot rather than a photo, a small corner radius on both the image and the outer canvas usually looks the most polished.

Exporting the final image

Once the border looks right, export as PNG if you need maximum quality or transparency support, or JPG for a smaller file size — JPG is usually the better choice for photos with a solid or gradient border since there's no transparency to preserve. If the final file is too large for where you're posting it (email, a website, a form upload), run it through a compressor afterward without affecting the border you just added.
