How do I create a thumbnail with Add Screenshots?

Add scale_fit=WIDTHxHEIGHT to your API request to resize the screenshot while keeping aspect ratio.

What if I need an exact width and height?

Use scale_crop to resize and crop the screenshot to an exact size, or scale_factor for proportional scaling.

Can thumbnails be delivered to my storage automatically?

Yes. Add Screenshots can send thumbnails to AWS S3, Azure Blob Storage, Google Cloud Storage, Cloudflare R2, FTP, or email in the same request.

Transforming full-size screenshots into thumbnails is essential for creating more manageable images from high-resolution captures. This process helps in optimizing your images for various use cases, including website previews, social media sharing, and more.

Why Convert to Thumbnails?

Thumbnails are useful for:

Faster Load Times: Smaller image files load quicker, improving page load speeds and user experience.
Efficient Space Utilization: Thumbnails save space and reduce bandwidth usage, especially for large collections of images.
Enhanced Presentation: Thumbnails are ideal for gallery views, previews, and for providing users with a quick glimpse of content.

Scale to Fit (Thumbnail)

This method converts a high-resolution screenshot into a smaller thumbnail, adjusting the image dimensions to fit within a specified size (e.g., 300x400 pixels).

Scale Factor

Apply scaling with a specific factor to adjust the size of a full-size screenshot to fit within defined dimensions (e.g., 300x400 pixels), maintaining the aspect ratio as much as possible.

// Example API request for scaling factor https://api.addscreenshots.com/screenshots
?apikey=YOUR_API_KEY
