WORKS WITH YOUR EXISTING STORAGE
Unlike Cloudinary or ImageKit, we don't force you to upload images to our servers. Keep your existing storage and workflow.
Keep your images on S3, GCS, Azure, or R2. We transform on-the-fly — no uploads, no sync, no lock-in.
Resize to exact dimensions + WebP/AVIF conversion + edge caching = dramatically faster page loads.
Flat monthly fee. No bandwidth surprises, no per-transformation costs, no bill shock.
Just prefix your URLs. No SDK, no build step, no code changes beyond a simple find-and-replace.
Allowlist your storage domain (e.g., mybucket.s3.amazonaws.com)
Change image sources to fastimage.dev/i?url=...
Append &w=400&format=webp — that's it, you're done.
FastImage is designed for developers who want image optimization without vendor lock-in or surprise bills.
