Image Border Maker guide
Add an even solid-color border around a JPG, PNG, or WebP image by expanding its canvas.
What this tool does
The Image Border Maker adds the selected number of pixels to all four sides of an image. A 40-pixel border increases both width and height by 80 pixels because it adds 40 pixels on each opposing edge. The original image remains centered without stretching, cropping, or resampling.
The new area is filled with one solid color chosen through the browser color picker. Output uses the source image’s supported format and retains the original image pixels at their decoded dimensions. The browser creates a new downloadable file and leaves the source untouched.
This tool makes an outside border rather than drawing a stroke over the image. As a result, none of the original edge content is covered. It does not create patterned frames, drop shadows, captions, separate widths per side, transparent padding, or print bleed guides.
How to use it
- Choose a JPG, PNG, or WebP image up to 25 MB for the bordered canvas.
- Enter a border width from zero through 2,000 pixels.
- Pick the solid border color.
- Select Add border.
- Check the reported output dimensions and download the new image.
Choose width according to the source resolution. Forty pixels can look substantial on a small icon but narrow on a large photograph. For a proportional frame, calculate the border as a percentage of the shorter image dimension before entering pixels.
Use Round Image Corners when the asset needs transparent curvature rather than an added rectangular frame.
Benefits
- Adds equal padding on every edge
- Preserves the complete original image area
- Reports expanded output dimensions
- Supports solid colors and common web formats
- Prevents unsafe oversized canvas output
- Runs locally without an upload
Format and layout notes
The border becomes permanent pixel content. JPEG cannot store transparency, but this tool uses an opaque selected color in every format. Re-encoding can remove unsupported metadata and alter file size. If a publishing system will crop or resize the upload automatically, test that workflow before choosing the final border width.
