Need extra whitespace around your image? The MyPDF Add Padding tool extends the canvas in any direction with a custom background color — ideal for social media aspect ratios, print margins, and presentation layouts.
How to Add Padding
- Upload your image (JPG, PNG, or WebP).
- Set padding values for each side (top, right, bottom, left) and choose a background color.
- Download the padded image instantly.
Padding Use Cases
| Use Case | Padding Amount | Background |
|---|---|---|
| Instagram square fit | Auto to fill 1:1 | White or black |
| Print bleed margins | 3-5 mm equivalent | White |
| Presentation slides | 50-100 px per side | Match slide color |
| Text space below image | Bottom only, 100+ px | White |
Practical Tips
- Use equal padding on all sides to center a landscape image within a square canvas for Instagram.
- Set transparent background (PNG only) if you need padding without a visible color fill.
- Match the padding color to your website or social media profile background for a seamless look.
What is the difference between padding and border?
Padding extends the canvas with a flat background color. A border adds a visible outline or frame around the image. Both increase the overall dimensions.
Can I add padding asymmetrically?
Yes. You can set different padding values for each side — for example, add 200 px to the bottom for caption space while keeping other sides at 0.
