Add a Custom Border to Any Image Online
Frame a JPG, PNG, or WebP image without uploading it. Pick an exact border color and width, place the border inside or outside the photo, round the corners, preview the result, and download a new image in your preferred format.
How to use this tool
- 1
Add Your Image
Choose a JPG, PNG, or WebP file from your device, or drag it into the workspace. The browser reads the image locally and shows its dimensions.
- 2
Choose Width and Color
Move the width control from a thin line to a bold frame and use the color picker to select the exact border color you want.
- 3
Set the Border Position
Place the border outside to preserve every original pixel and enlarge the canvas, or place it inside to keep the original output dimensions.
- 4
Adjust the Corner Radius
Keep square corners at zero or increase the radius for a softer rounded frame. The live preview updates with every setting change.
- 5
Choose a Format and Download
Export the finished image as PNG, JPG, or WebP. The tool creates a new bordered copy and leaves your original file unchanged.
What it can do
Custom Border Width
Create anything from a subtle one-pixel outline to a wide 200-pixel frame, with safeguards for very small images when the border is inside.
Exact Color Picker
Select any border color and see its hexadecimal value, making it easy to match a brand palette, background, layout, or design system.
Inside or Outside Placement
Use an outside border when the whole photo must remain visible, or an inside border when the final width and height must stay unchanged.
Rounded Corner Control
Set the corner radius from square to strongly rounded and preview how the border and image edges will look before export.
PNG, JPG, and WebP Output
Choose lossless PNG, broadly compatible JPG, or efficient WebP according to transparency, photo compatibility, and file-size needs.
Private Browser Processing
Image decoding, border rendering, format conversion, and download creation happen on your device. TunerPage does not receive the working image.
Useful for
- Adding a clean frame around profile photos and social posts
- Matching product images to a consistent storefront or marketplace style
- Creating white borders around photographs before printing
- Using a brand color around thumbnails, cards, and presentation graphics
- Rounding image corners for website mockups and interface previews
- Expanding an image canvas without cropping any of the original content
Limits to know
- An inside border covers pixels along the original image edges instead of adding canvas space
- An outside border increases the final width and height by twice the selected border width
- JPG output cannot preserve transparent rounded corners, so those areas use a white background
- Very large images may require substantial browser memory while the full-resolution copy is rendered
- The tool creates one solid-color border and does not add patterns, textures, shadows, or decorative frames
Private browser processing
This tool runs locally in your browser. TunerPage does not upload the working file or text to its servers.
Frequently asked questions
How do I add a border to an image?
Add a JPG, PNG, or WebP image, choose the border width and color, select inside or outside placement, adjust the corner radius, and choose Create and download.
What is the difference between an inside and outside border?
An outside border adds new canvas space around the image and preserves every source pixel. An inside border draws over the edge pixels while keeping the original dimensions.
Can I add a white border to a photo?
Yes. Open the color picker and select white, then choose the desired width. An outside white border is useful for prints, galleries, and social layouts.
Can I make the image corners rounded?
Yes. Increase the corner radius to round both the border and visible image edge. PNG or WebP can keep transparent pixels outside rounded corners.
Will the border reduce my image resolution?
The image itself is not scaled. Outside placement increases the canvas dimensions, while inside placement keeps the original dimensions and covers pixels at the edges.
Which download format should I choose?
Choose PNG for lossless output or transparent rounded corners, JPG for widely compatible photographs, and WebP for efficient modern web images.
Is my image uploaded to TunerPage?
No. The file is decoded, previewed, rendered, and exported in your browser. The working image is not sent to TunerPage for processing.
Does the tool change my original image?
No. It creates a separate bordered file for download. Your original file remains unchanged on your device.
