Add Image Padding
Add precise breathing room around any browser-supported image. Set each side independently, choose a fill color, and export the expanded canvas.

What this tool does
A larger canvas is filled with the selected color before the source image is drawn at the left and top offsets.
Processing stays in the current browser tab. Closing or resetting the page releases temporary preview URLs.
Supported formats and limits
The file picker accepts the formats shown above. Actual decoding support is controlled by the browser. Images above 60 megapixels are blocked to reduce memory crashes, and canvas-generated output does not retain source metadata.
| Stage | Behavior |
|---|---|
| Input | Browser-decoded image files |
| Processing | Local Canvas, File, and Blob APIs |
| Output | New downloadable result |
Tips for better results
- Start from the highest-quality practical source.
- Check small text and edges at full preview size.
- Keep a copy of the original because browser exports may remove metadata.
- For large batches, process fewer files at a time on mobile devices.
FAQ
Does Add Image Padding upload my image?
No. Processing runs in your browser. The page does not send the selected image to a processing server.
Which image formats work with Add Image Padding?
The tool accepts the formats listed on the page, but decoding still depends on your browser. AVIF and some unusual files may not open in older browsers.
Will image metadata be preserved?
Canvas-generated image outputs normally omit EXIF and other source metadata. The batch rename tool copies original bytes, while its ZIP changes filenames only.
What happens with very large images?
The tool rejects images above its pixel safety limit because large canvases can exhaust memory, especially on phones. Resize the source first if needed.
Can I use the downloaded result immediately?
Yes. The download is a newly generated image or report. Check the preview and dimensions before publishing or archiving it.
