Add Padding to Image

Add exact padding around a photo or fit it into a 1:1, 4:5, 16:9 or 9:16 canvas without cropping or stretching it.

Padded image

Your file is never sent to a server. It is read and processed by your own browser, and the results are not stored.

How to use it

  1. Choose a JPG, PNG or WebP image.
  2. Pick uniform padding in pixels, or an aspect-ratio preset for social and print sizes.
  3. Choose the background, convert, then download the padded image.

Limits worth knowing

  • The image itself is never scaled or cropped; only the canvas grows.
  • Uniform padding is limited to 2000 px per side and the canvas to 8192 px per side.
  • The padded canvas must stay under 40 megapixels.
  • Transparent padding requires PNG. JPEG output is flattened onto the chosen colour.
  • EXIF metadata is not copied into the output.

Padding without cropping

Most “make it square” tools crop the photo, which throws away the edges. Padding takes the opposite approach: the whole picture stays, and the canvas grows around it. For a product photo, a print layout or a social post that must not lose content, that is usually the safer choice.

The aspect presets solve the common cases. A 4:5 preset adds space above and below a landscape photo, for example, while a 9:16 preset adds space left and right of a portrait. The picture is centred to the nearest pixel.

Choosing a background

White is the default for forms and marketplaces. A brand colour can make a transparent logo sit on a consistent field. Transparent padding is useful when the result will be composited again, but it only survives in PNG; JPEG has no alpha channel.

Frequently asked questions

Does Add Padding to Image upload my files to any server?

No. Add Padding to Image runs in your browser, and the file is read there rather than sent to a server for processing. Our host still sees ordinary page-request metadata, which is described on the privacy page.

Is Add Padding to Image free to use?

Yes, Add Padding to Image is free, with no paid tier, no account, and no watermark added to your output. The limits are technical rather than commercial: file size, page count and supported formats are listed on this page.

What file formats and sizes are supported?

Add Padding to Image supports .jpg, .jpeg, .png, .webp files up to 25MB directly in your browser.

How is padding different from a border?

Padding enlarges the canvas around the picture, so the original pixels keep their size and gain breathing room. A border is drawn around the picture inside the same canvas. Use the Add Border tool when you want a visible frame rather than extra space.

Does the image get stretched to the new shape?

No. The original pixels are placed at their exact size and centred. Padding fills the remaining area with your chosen colour or transparency. Nothing is scaled or cropped.

Can I create a square image for Instagram?

Yes. Choose “Fit to aspect ratio” and Square · 1:1. The tool adds space on the short side and keeps the whole picture. For a 4:5 feed post or a 9:16 story, choose the matching preset.

Can the padding be transparent?

Yes for PNG output. JPEG cannot store transparency, so transparent padding is refused for JPEG or flattened to white. The tool states which behaviour applies before you download.
