When a border is the right tool
Borders separate an image from a similar-toned page background and hold a grid of thumbnails together. Use one where you need that edge without changing the canvas size.
Image Border Resizer
A border is drawn inside the existing edge of the picture, so the image keeps its dimensions while the frame sits over its outer pixels. Set the thickness and the colour here, and check that nothing important sits close enough to the edge to be covered.

Image Border Resizer常見問題
Does a border reduce the visible picture?
Yes, the frame covers the outer band of the image. If the picture must stay untouched and the canvas grow instead, add padding.
What border width should I use?
Scale it with the image: a few pixels vanish on a large file while the same setting swamps a small icon.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Framed image.
What should I check before using the result?
Open the Framed image in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.

Before downloading the result
Open the Framed image next to the original at full size and check text edges, faces, and flat backgrounds; re-encoding softens detail long before it looks wrong in a thumbnail.
What this image border resizer does
Add a border around an image and place the result on a consistent canvas. You can choose the final width and height, border width, border color, background color, and output format. The tool is useful for product catalogs, social posts, presentation graphics, thumbnails, and image sets that need the same visual spacing.
The border is drawn inside the final canvas. The target dimensions describe the complete downloaded image, including the border and the image area. This keeps a batch of outputs predictable when it moves into a website, store listing, or design workflow.
How to add a border and resize
- Upload one or more JPG, PNG, WEBP, or SVG images.
- Enter the final canvas width and height.
- Set the border width in pixels and choose a border color.
- Choose the image fit mode, background color, and output format.
- Select Create & Download to save the result. Multiple images are downloaded as a ZIP file.
Common uses for image borders
A border gives separate images the same outer spacing when their source dimensions are different. White borders are common for product images and marketplace catalogs. Dark borders can help screenshots stand out on light pages. A border can also make a portrait or landscape photo fit a square layout without cutting away the subject.
Choosing the output format
PNG is a good choice for sharp graphics and images that need clean edges. JPG is useful for photographic images and usually creates smaller files. WEBP can reduce file size when the destination supports it. Always check the receiving service's current format and size requirements.
Privacy and file handling
The image is read and processed in the browser. The result is created with the Canvas API and saved through the browser download flow. No server-side image processing is required for this tool.
Frequently Asked Questions
Are the final dimensions exact?
Yes. The width and height fields describe the complete output canvas. The border is included inside those dimensions.
Can I add the same border to several images?
Yes. Upload multiple files and the same border and canvas settings are applied to each result.
Does a border improve image quality?
A border changes the canvas and layout. It cannot restore detail that is missing from a small source image. Review the row preview the list draws at output size, especially when enlarging a photo.
