Key features

Dynamic resizing: Adjust image dimensions using width and height parameters to suit various display requirements.
Quality control: Set image quality on a scale from 20 to 100 to balance visual fidelity and file size.
Resize modes: Choose from ‘cover’, ‘contain’, or ‘fill’ to control how images fit within specified dimensions.
Automatic format optimization: Automatically convert images to WebP format for supported browsers, enhancing load times and reducing bandwidth usage.
Flexible implementation: Utilize with public URLs, signed URLs, or direct downloads to fit various access control needs (Server-side Auth).
Next.js integration: Leverage a custom loader for optimized image handling in Next.js applications.
Self-hosting option: Deploy your own image transformation service using Imgproxy for greater control and customization.

Benefits:

Performance optimization: Reduce bandwidth usage and improve load times with optimized images.
Storage efficiency: Store a single high-quality version and generate variants as needed.
Responsive design support: Serve appropriately sized images for different devices and layouts.
Simplified workflow: Automate image processing tasks, reducing the need for manual intervention and third-party tools.

Image transformations are valuable for:

Responsive web applications: Deliver images optimized for various screen sizes and resolutions.
Ecommerce platforms: Showcase product images in multiple sizes without storing redundant files.
Content management systems (CMS): Adapt images for different layouts and templates dynamically.
Mobile applications: Optimize images for devices with varying bandwidth and display capabilities.
High-volume image handling: Efficiently manage and serve large quantities of images in diverse contexts with resumable uploads.

Supabase's Image Transformations feature enables you to efficiently manage and serve optimized images, improving your application's performance and user experience while saving time and resources.

FAQs about image transformations with Supabase

Below are answers to common questions about Supabase Image Transformations.

What image formats are supported by Supabase Image Transformations?

Supabase Image Transformations primarily support common web-friendly formats such as JPEG, PNG, and WebP. When using the automatic format optimization feature, images can be converted to WebP for supported browsers to enhance performance.

Can I apply multiple transformations to a single image request?

Yes, you can chain multiple transformation parameters in a single request. For example, you can resize an image and adjust its quality simultaneously by specifying the appropriate query parameters in the image URL.

How do I implement transformations in my Next.js application?

Supabase provides a custom loader for Next.js, allowing seamless integration of Image Transformations. By configuring the loader, you can optimize images on-the-fly within your Next.js project.

Are there any limitations on image size or dimensions?

While Supabase does not impose strict limits on image sizes, it’s recommended to optimize images for web use to ensure faster load times and better performance. Large images may consume more bandwidth and affect loading speeds.

How does automatic format optimization work?

Automatic format optimization detects the capabilities of the user’s browser and serves the most efficient image format supported, such as WebP. This enhances loading times and reduces bandwidth usage without compromising image quality.
