Cloudflare (R2 & Edge CDN) + Cloud CDN Integration

How your cloud storage, SmallPict's conversion step and the CDN fit together.

Dedicated storage origin

Cloudflare R2 is S3-compatible object storage with no egress fees, so large media libraries don't bring surprise bandwidth bills.

SmallPict ephemeral engine

SmallPict is an image optimization platform. It picks up image uploads, converts them to AVIF and WebP in memory, strips unneeded EXIF metadata, resizes them, and writes the optimized files straight to your cloud storage bucket.

Global edge CDN delivery

Cloudflare Anycast CDN operates across 300+ cities in 100+ countries, serving cached assets directly from the internet's closest edge with automatic modern format negotiation.

Visual architecture & integration flow

Your images are converted in memory, saved to your bucket and served from the CDN.

How to Connect Cloudflare (R2 & Edge CDN) to SmallPict

A 4-step setup guide to provision buckets, configure least-privilege credentials, connect endpoints, and verify edge delivery.

  1. Provision Dedicated Cloudflare R2 Bucket

    Create a dedicated bucket or container in your Cloudflare (R2 & Edge CDN) console (Standard storage class recommended).

    Tip: Keep the bucket private; public access is not required.

  2. Configure IAM / scoped credentials

    Generate Cloudflare R2 API Token with least-privilege permissions strictly scoped to read and write objects in your bucket.

    Tip: Only PutObject and GetObject permissions are required.

  3. Link endpoint in SmallPict dashboard

    Enter your bucket name, region, endpoint, and API credentials into the SmallPict BYO settings panel.

    Tip: Credentials are encrypted at rest with AES-256 GCM.

  4. Test & verify edge asset delivery

    Upload a test asset or run an automated URL verification. Check response headers for Content-Type: image/avif and CDN cache HIT status.

    Tip: Verify Cache-Control: public, max-age=31536000, immutable.

Why Use SmallPict with Cloudflare (R2 & Edge CDN)?

5 strategic architectural advantages designed to eliminate vendor lock-in, reduce latency, and lower operational overhead.

Much lighter

Reduce image payload

Converts PNG and JPEG to AVIF and WebP with no visible quality loss. How much smaller depends on the image.

Your own bucket

Keep your existing storage

Bring your own storage: SmallPict writes straight into your Cloudflare R2 bucket, so your files never move to a closed platform.

Edge delivery

Global edge delivery

Maximize edge cache hit ratios with long-lived immutable cache headers across Cloudflare CDN global points of presence.

Automatic

Automated optimization

Images convert in the background on upload or batch sync. No manual resizing or scripts.

Full control

Infrastructure control

You retain complete ownership, access control policies, IAM boundaries, and compliance governance over your assets.

Ready in 5 mins

Drop-in integration

Connect through the WordPress plugin, the API or the dashboard. No changes to your infrastructure, code or database schema.

Security, privacy & access control

Does SmallPict keep or store copies of my files?

Not when you bring your own storage. Images are processed in isolated, encrypted processing storage, and the optimized files are written straight to your Cloudflare R2 bucket. Your files live in your own account: you keep your originals and are responsible for those copies, and SmallPict does not keep a backup of them.

No copies kept after conversion

Least-privilege IAM

SmallPict requires only bucket-scoped read and write permissions (e.g. PutObject / GetObject). We never request or require administrative, project-wide, or account-wide credentials.

Private bucket support

Your Cloudflare R2 buckets do NOT need to be public. SmallPict writes directly using authenticated API calls, and asset delivery is routed securely via CDN Origin Access Control or signed origins.

AES-256 encryption

All API tokens and credentials stored in SmallPict are encrypted at rest using AES-256 GCM envelope encryption and never logged in plaintext.

Customer sovereignty

The files stay yours. You can revoke credentials or rotate keys at any time in your Cloudflare (R2 & Edge CDN) console.

Image Optimization for Cloudflare (R2 & Edge CDN)

Technical specifications covering AVIF, WebP, compression algorithms, responsive dimensions, and cacheability.

AVIF format

Much smaller than JPEG/PNG

AVIF (AV1) encoding

AVIF uses AV1 keyframe compression, which gives the best quality for its file size of any format browsers support today.

WebP format

Smaller than JPEG/PNG at the same visual quality

Universal modern compatibility

Supported in all current browsers, with alpha transparency kept and perceptual quantization.

Edge caching

1-year edge cache

Immutable cache-control

Automatically attaches public, max-age=31536000, immutable to maximize edge retention.

  • 1-Year immutable CDN edge caching to prevent redundant origin requests
  • Automatic browser format negotiation via HTTP Accept headers
  • Responsive downscaling with srcset width descriptors
  • Faster Largest Contentful Paint (LCP)

Lower egress bills from smaller files

Why optimizing image weight directly lowers your cloud provider monthly invoice without paying inflated SaaS CDN markups.

Without SmallPict (raw media)

Heavy egress bandwidth & slower pages

Raw, unoptimized JPEG/PNG images (2.5MB–5MB each) consume excessive storage and drive heavy outbound egress bandwidth charges from Cloudflare (R2 & Edge CDN).

  • Heavy 2.5MB - 5MB original image weights
  • Full cloud provider egress bandwidth charges
  • Higher LCP latency impacting Google search rankings

With SmallPict + Cloudflare (R2 & Edge CDN)

Lower egress bandwidth bills from your cloud provider

Smaller payloads mean less outbound data transfer, which lowers your cloud provider egress bill every billing cycle.

  • Images served from Cloudflare Global Anycast Edge Network edge locations close to your visitors
  • You pay Cloudflare (R2 & Edge CDN) directly at its own cloud rates, with no markup from a closed image CDN.
  • Year-long cache headers, so the CDN answers repeat requests from the edge

Frequently asked questions

Clear technical answers regarding Cloudflare (R2 & Edge CDN) storage integration, CDN cache headers, security policies, and performance.

What is Cloudflare R2 + Cloudflare CDN Integration?

Cloudflare R2 keeps your files, and Cloudflare CDN serves cached copies from the edge locations closest to your visitors. SmallPict sits in between and compresses images before they are stored and delivered.

Can SmallPict optimize images stored in Cloudflare R2?

Yes. SmallPict connects directly to your Cloudflare R2 buckets. It compresses JPEG, PNG, and WebP assets, converts them to AVIF and WebP, and stores the optimized files directly inside your bucket.

Does SmallPict work with Cloudflare CDN?

Yes. When SmallPict streams optimized images to Cloudflare R2, it attaches long-lived HTTP caching headers (Cache-Control: public, max-age=31536000, immutable). Cloudflare CDN caches these assets at the edge and answers repeat requests from there.

Can I use a private Cloudflare R2 bucket?

Absolutely. SmallPict does NOT require your bucket to be public. SmallPict writes directly using authenticated API calls, and public delivery is handled securely via CDN Origin Access Control or private origin configurations.

Does SmallPict require Cloudflare (R2 & Edge CDN) administrative credentials?

No. SmallPict operates on least-privilege principles and only requires credentials (Cloudflare R2 API Token) with scoped permissions strictly restricted to reading and writing objects within your specific target bucket.

Can I use a multi-region Cloudflare R2 bucket?

Yes. SmallPict fully supports multi-region, dual-region, and regional bucket configurations. SmallPict will push optimized assets to whichever endpoint you configure in your SmallPict dashboard.

Does SmallPict alter or overwrite my original images?

By default, SmallPict generates modern optimized formats (.avif and .webp) alongside your original master files, preserving your original images untouched unless you explicitly configure in-place replacement.

Where are optimized images stored?

All optimized images are stored directly in your own Cloudflare R2 bucket, in your own account. With BYO storage you keep your originals and are responsible for those copies; SmallPict does not keep a backup of them.

Does SmallPict support WebP and AVIF formats?

Yes. SmallPict natively encodes both AVIF and WebP, which are typically much smaller than JPEG. When delivered through Cloudflare CDN, assets are served dynamically according to the visitor's browser support.

How does caching work after image optimization?

SmallPict injects Cache-Control: public, max-age=31536000, immutable headers into every stored asset. This tells Cloudflare CDN edge nodes and client browsers to cache the image for up to one year, so repeat requests rarely reach your origin and origin transfer fees stay low.

Keep your storage, control your egress bill

Deploy SmallPict with Cloudflare (R2 & Edge CDN). Keep your media assets inside your own cloud account while enjoying automated AVIF/WebP encoding and global edge acceleration.
