How do I crop an image to ad size for free?

Use Alvseike's free Ad Cropper. Open the tool, drag and drop your image onto the drop zone, select your target ad size from presets like leaderboard or medium rectangle, adjust the crop area, and export. It's free, with no uploads and no file-size caps.

What are the standard ad sizes for banners?

Common IAB ad sizes include leaderboard (728x90), medium rectangle (300x250), large rectangle (336x280), skyscraper (160x600), and mobile leaderboard (320x50). The Ad Cropper includes these presets, so you don't have to remember them.

Can I crop a large image for an ad without losing quality?

Yes. The Ad Cropper processes your image locally, so there are no file-size caps. You can crop high-resolution images without quality loss. Just adjust the crop area to the desired ad size and export in PNG or JPG format.

Is it safe to use an online ad cropper with my images?

Alvseike's Ad Cropper is safe because it runs entirely in your browser. Your images are never uploaded to any server. This means your creative stays private and secure. There are no third-party trackers or data collection during the process.

Can I crop multiple images to ad size at once?

The Ad Cropper processes one image at a time. If you have multiple images, you'll need to crop them individually. However, the process is fast, and you can quickly repeat it for each image without any upload delays.

How to Crop an Image to Ad Size

Need to crop an image to ad size for a banner, social post, or display campaign? The Ad Cropper lets you do it in seconds, right in your browser, without uploading your file to any server. Just drag and drop your image onto the drop zone, choose your target ad size, and export the perfectly cropped creative.

Why Use a Dedicated Ad Cropper?

Generic photo editors are overkill and often lack the preset dimensions you need for digital advertising. A dedicated ad cropper comes with standard ad sizes built in, so you don't have to remember that a leaderboard is 728x90 or that a medium rectangle is 300x250. It saves time and reduces errors, especially when you're producing multiple creatives for a campaign.

Step-by-Step: How to Crop an Image to Ad Size with Alvseike's Ad Cropper

Here's the entire process, from start to finish:

Open the Ad Cropper tool in your browser. No sign-up, no account, no software to install.
Drag and drop your image onto the drop zone. You can also click 'browse' to select a file from your computer. The tool accepts common formats like JPG, PNG, and WebP.
Select your target ad size from the list of presets. Choose from standard IAB sizes like leaderboard (728x90), medium rectangle (300x250), large rectangle (336x280), or skyscraper (160x600). You can also enter custom dimensions if you need a specific size.
Adjust the crop area by dragging the crop box. You can reposition it to focus on the most important part of your image. The tool shows you the final dimensions as you adjust.
Export your cropped image. Click the export button to download the file to your device. That's it — your ad creative is ready to use.

Why Local Processing Beats Upload-Based Tools

Most online image editors require you to upload your file to their servers, which raises privacy concerns and often comes with file-size limits. Alvseike's Ad Cropper processes everything locally on your device. Your image never leaves your computer, so there's no risk of your creative being intercepted or stored on a third-party server. This also means there are no file-size caps — you can crop even the largest, highest-resolution files without a problem. And because there's no upload step, the whole process feels instant.

Common Mistakes and Pro Tips

Don't stretch your image: If your original image isn't the same aspect ratio as the target ad size, you'll either need to crop (which the tool does) or risk distortion. Always crop rather than stretch.
Keep important elements centered: For banners, keep your logo and key message within the safe area, away from the edges, to avoid them being cut off on smaller screens.
Use the right file format: For ads with text or logos, PNG is usually better. For photographic images, JPG gives a smaller file size. The tool lets you export in both.
Preview on different devices: After cropping, test your ad on a desktop and a mobile device to ensure it looks good in both contexts.
Batch similar crops: If you have multiple images that need the same ad size, crop them one by one — the tool is designed for single-file processing, so plan accordingly.
