Question 1

What counts as a transformation?

Accepted Answer

A transformation is any request that modifies the image (resize, format conversion, quality adjustment). Cached requests from the CDN don't count toward your limit.

Question 2

What happens when I reach my limit?

Accepted Answer

On the Free plan, uploads and transformations are blocked until the next billing cycle. On the Pro plan, you can purchase Resource Packs ($10 each) to extend your quota instantly with +10 GB storage, +10,000 API requests, and +10,000 transformations.

Question 3

Can I downgrade from Pro to Free?

Accepted Answer

Yes, you can cancel your Pro subscription anytime. Your images remain accessible, but you'll be limited to Free plan quotas after the billing period ends.

Question 4

Is there a bandwidth limit?

Accepted Answer

No. Thanks to Cloudflare R2's zero egress fees, img-src.io offers unlimited bandwidth on all plans at no extra cost.

Question 5

What image formats does img-src.io support?

Accepted Answer

Input formats: JPEG, PNG, WebP, GIF, BMP, TIFF, ICO, SVG, HEIC/HEIF, AVIF, TGA, PNM, QOI, HDR, EXR. Output formats: WebP (default), AVIF (max 8 megapixels), JPEG, PNG. Images are converted on-the-fly by changing the file extension in the URL.

Question 6

How do I transform images with img-src.io?

Accepted Answer

Add URL parameters to your image URL. Use ?w=800 for width, ?h=600 for height, ?fit=cover for crop mode, ?q=85 for quality. Change the file extension to convert format (e.g., photo.webp, photo.avif). Example: https://img-src.io/i/user/photo.webp?w=800&q=85
