# Add Border — Add a border to photos on Mac

Pad photos with an even white, black, coloured, blurred or transparent border. Part of OneMacTools, 151 private tools in one native Mac app (macOS 26 or later); category: Images. Runs on your Mac; nothing is uploaded.

The canvas grows outwards, so the photo itself is never cropped. Choose a thickness in pixels or as a share of the width, so a batch of different sizes looks the same, and a white, black, custom, blurred-photo or transparent border. Optionally round the photo's corners.

## How to use it
1. **Drop your photos.** Drag in one photo or a whole batch. Each one gets its own bordered copy.
2. **Choose the thickness.** Pick a fixed size in pixels, or a percentage of the width so photos of different sizes get borders that look the same.
3. **Choose the colour.** White, black, transparent, a blurred copy of the photo itself, or Custom with your own hex colour. Turn on rounded corners if you want a softer look.
4. **Click Add Border.** The canvas grows outwards by the border on all four sides, so nothing in the photo is cropped.
5. **Open the results.** The bordered copies are saved in a dated folder in Downloads › OneMacTools. Use the Preview (eye) button to check them, or Show in Finder.

## Options
- **Thickness:** How wide the border is on every side: 10, 20, 50 or 100 px, or 2%, 5% or 10% of the photo's width. The default is 5% of width, which keeps a batch of mixed sizes looking consistent. The percentage is worked out from the width and applied to all four sides, so the border is always even.
- **Colour:** White, Black, Transparent, Blurred photo or Custom. Blurred photo fills the border with a soft, slightly darkened blur of the same picture. Transparent saves a PNG so the border can sit on any background.
- **Colour (hex):** Only shown when Colour is Custom. Type a hex value such as #F4E9DC, or a simple name like grey, red, blue or yellow. If the value can't be read, the border falls back to white.
- **Round the photo's corners:** Rounds the corners of the photo inside the border, by a small amount relative to its shorter side. The corners show the border colour, or stay see-through with a transparent border.

## Tips
- Use a percentage thickness for batches. A 20 px border looks thick on a small image and thin on a 4000 px phone photo; 5% of width looks the same on both.
- For an instant-print look, use a white border at 5–10% of width, then make the bottom deeper by cropping or placing it in a collage.
- Blurred photo works well for social posts: the edges pick up the photo's own colours, so it never clashes.
- Choose Transparent with rounded corners when you want a rounded photo to drop onto a web page or slide.
- Borders on a JPEG are saved as JPEG at high quality. If you'll edit the file again later, start from a PNG to avoid compressing it twice.

## Questions
**How do I add a white border to a photo on a Mac?**
Drop the photo onto Add Border, leave Colour on White, choose a thickness and click Add Border. You get a new copy with an even white frame on all four sides.

**Does adding a border crop my photo?**
No. The canvas grows outwards to make room for the border, so every pixel of the original photo is still there.

**Can I add the same border to many photos at once?**
Yes. Drop them all in together. Choose a percentage thickness so the border looks the same whatever each photo's size.

**How do I add a coloured border?**
Set Colour to Custom and type a hex value such as #1E90FF into Colour (hex). A few names like black, grey, red and blue work too.

**Can the border be transparent?**
Yes. Choose Transparent and the copy is saved as a PNG with see-through padding, which is useful for adding space around a logo or cut-out.

**What does the Blurred photo border do?**
It fills the border with a blurred, slightly darker version of the same photo, so the frame matches the picture's colours instead of being a flat colour.
