Why is border width set as a percentage instead of a fixed pixel number?

A percentage scales sensibly regardless of the image's original resolution — a border that looks right on a small image would look too thin on a much larger one at the same fixed pixel width, so scaling proportionally keeps the visual weight consistent across different image sizes.

Can I add the same border to multiple images at once?

Yes, upload several images and the same border width, color, and corner style applies to all of them, downloaded together as a ZIP — useful for giving a matching set of photos a consistent frame.

What's the difference between solid and rounded corner style?

Solid keeps sharp right-angle corners on the border, the traditional framed-photo look. Rounded softens the outer corners of the whole bordered image into a curve, a more modern style often used for social media or app-style image previews.

Does adding a border crop or resize my original image?

No — the original image is placed at its full original size, and the border is added around it, so the final image is larger than the original by the border width on each side rather than the source content being cropped or shrunk to make room.

Can I use a custom color that's not in the preset swatches?

Yes, the custom color picker next to the presets lets you choose any color at all, so the border can match a specific brand color or a shade picked directly from another image.

Will the border be added to a transparent image with a transparent background too?

Yes — the border is drawn as an opaque solid color regardless of what's beneath it, so it appears correctly even around an image with a transparent background, like a PNG logo.

Is my image uploaded to a server for this?

No. The border is drawn entirely in your browser using canvas, and your images are never transmitted anywhere.

Why add borders to images with Tools Root

A border can turn a plain photo into something that reads as intentionally framed — for a portfolio, a social post, or a printed keepsake. This free image border tool adds a solid or rounded-corner border directly in the browser, with full control over width and color.

Proportional sizing, batch-friendly

Setting border width as a percentage of the image's own size keeps the border looking correctly proportioned whether it's applied to a small thumbnail or a full-resolution photo, and applying the same settings across a batch of images at once keeps a whole set visually consistent.

A free photo border and frame tool with no watermark

Photo editing apps often lock border and frame features behind a paid tier. This tool adds a clean, customizable border at no cost, with a genuine choice of color and corner style rather than a small set of fixed preset frames.

Common use cases

Adding a consistent white border to a set of photos before posting to social media, framing a product photo for an online listing, adding a rounded-corner border to app screenshots for a portfolio, creating a printable photo with a traditional frame border, or giving a batch of event photos a matching branded border color.

Before or after adding a border

If the image needs cropping or resizing first, Resize Image and Crop Image handle that ahead of framing, and Watermark Image can add a text or logo overlay afterward.

Choosing a border width that looks intentional

A very thin border can read as accidental or barely noticeable, while a very wide one starts to dominate the image itself — a width in roughly the 2 to 6 percent range tends to read as a deliberate, classic frame for most photos, though a bolder statement border can work well for social graphics specifically designed around a thicker frame.

Matching a border color to its context

A plain white or black border tends to work neutrally across most photos and contexts, while a custom brand or accent color makes more sense when the framed image is going somewhere with an existing visual identity to match, like a business's product photos or a themed social media account.
