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

  1. Upload your image (JPG, PNG, or WebP).
  2. Set padding values for each side (top, right, bottom, left) and choose a background color.
  3. Download the padded image instantly.

Padding Use Cases

Print bleed margins3-5 mm equivalentWhite
Presentation slides50-100 px per sideMatch slide color
Text space below imageBottom only, 100+ pxWhite

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.
