Add Padding to an Image Online
Image Padding Generator lets you add padding to an image in your browser — surround a photo, icon, or logo with even whitespace, a solid background color, or transparent space, all without cropping the original. Set the final canvas size, choose how much margin you want, and download a perfectly spaced result.
It is built for app icons, favicons, logos, and product thumbnails that need consistent breathing room, and for social posts where you want to make an image square without cutting anything off. Drop in a picture, dial in the padding, and export to PNG, JPG, or WebP.
How to Add Padding to an Image
Add your image
Drag and drop an image onto the upload area, click to browse, or press Ctrl+V (Cmd+V on Mac) to paste from the clipboard. PNG, JPG, WebP, and GIF files are supported.
Set the canvas size
Pick a preset (32 up to 1024 px) or type custom width and height up to 4096×4096. Turn on Lock Aspect Ratio to keep the shape when you change one dimension.
Adjust padding and background
Drag the Padding slider from 0% to 50%, or switch the unit to pixels for exact spacing. Keep the background Transparent for icons, or pick a solid color for the margin.
Position and download
Drag the image on the canvas to reposition it, then choose PNG, JPG, or WebP and click Download. Switch to Batch mode first to pad many images and save them as a ZIP.
Features
Flexible Canvas Sizes
Use common presets from 32×32 to 1024×1024, or enter any custom size up to 4096×4096 pixels for matching icon sets.
Percentage or Pixel Padding
Set padding as a percentage of the canvas (0–50%) for proportional spacing, or switch to exact pixel values for precise control.
Transparent or Colored Background
Keep the padding transparent for PNG icons, or pick any solid background color to surround your image.
Auto-Trim Transparent Edges
Trim Transparent detects and removes existing transparent edges from the source so new padding stays accurate.
Multiple Fit Modes
Choose Contain to show the whole image, Cover to fill and crop, or Stretch to fill the area exactly.
Fill Transparent Areas
Fill Icon replaces see-through pixels inside the icon with a solid color while leaving the outer padding transparent.
Corner Radius
Round the image corners from 0% to 50% to create squircle or fully circular icons, leaving the background rectangular.
Free Positioning
Drag the image anywhere on the canvas, turn on center guides for alignment, or click Center to snap it back.
Rotation Support
Rotate images 90° clockwise, 90° counter-clockwise, or 180° without opening a separate editor.
Quality Modes
Use Smooth rendering for photos and illustrations, or Pixelated mode to keep crisp edges on pixel art.
Batch Processing
Switch to Batch mode to pad multiple images with the same settings and download them all as a single ZIP file.
Multiple Export Formats
Export as PNG for transparency, JPG for smaller photos, or WebP for modern compression, with an adjustable quality slider.
Settings Persistence
Canvas size, padding, fit mode, and other preferences are saved in your browser and restored on your next visit.
Frequently Asked Questions
How do I add padding around an image?
Add your image, set the canvas size, then drag the Padding slider. The tool centers your image and surrounds it with the spacing you choose — transparent or a solid color — before you download the result. Nothing is cropped from the original.
How do I add white space without cropping the image?
Use Contain fit mode. It scales the entire image to sit inside the padded area while keeping its aspect ratio, so the whole picture stays visible and the extra space becomes padding. Turn off Transparent and the margin fills with your chosen background color.
How do I make an image square for Instagram?
Set the same width and height (for example 1024×1024) for a square canvas, keep Contain fit mode, and add a little padding. A solid white background gives the classic bordered-photo look, while a transparent background keeps a PNG see-through.
Can I choose the padding background color?
Yes. Uncheck Transparent and use the color picker to set any background color for the padding. Leave Transparent on and the margin stays see-through, which is ideal for icons exported as PNG.
What image formats are supported?
You can load PNG, JPG, WebP, and GIF images. For export, choose PNG (best for transparency), JPG, or WebP, with a quality slider for the JPG and WebP formats.
What is the maximum canvas size?
The canvas supports dimensions up to 4096×4096 pixels. Very large images may take a little longer to process depending on your device.
What is the difference between Contain, Cover, and Stretch?
Contain shows the complete image, leaving padding on the sides when the aspect ratios differ. Cover fills the whole padded area and may crop parts of the image. Stretch resizes the image to fit the area exactly, which can distort it if the ratios do not match.
Can I pad multiple images at once?
Yes. Switch to Batch mode using the toggle at the top, add several images, and they are all processed with the same settings. Click Download ZIP to save the whole set in one archive.
How does Trim Transparent work?
When enabled, the tool scans the image to find the bounds of its non-transparent pixels and treats that area as the real content, ignoring any existing transparent edges. This keeps your new padding accurate even if the source already had uneven transparent borders.
Are my images uploaded to a server?
No. All processing happens locally in your browser using the Canvas API. Your images never leave your device, and nothing is stored or tracked.
