Integration Primer

Tencent Cloud (COS & Global CDN) + Cloud CDN Integration

How your cloud storage origin, SmallPict's ephemeral optimization engine, and the global edge delivery network work in perfect harmony.

1. Dedicated Storage Origin

Tencent Cloud Cloud Object Storage (COS) provides reliable, secure, and cost-effective object storage with native S3 XML API compatibility and deep APAC coverage.

2. SmallPict Ephemeral Engine

SmallPict is a next-generation media optimization platform that seamlessly intercepts image uploads, converts them into modern AVIF and WebP formats in ephemeral memory buffers, strips redundant EXIF metadata, resizes dimensions, and pushes optimized files straight to your cloud storage bucket.

3. Global Edge CDN Delivery

Tencent Cloud Global CDN utilizes 2,800+ acceleration nodes across Mainland China, Asia-Pacific, North America, and Europe to deliver optimized assets with sub-20ms edge latency.

Security & Data Governance

Security, Privacy & Access Control

Zero-Storage Retention Model

Does SmallPict keep or store copies of my files?

No. SmallPict operates on a strict ephemeral in-memory processing architecture. Assets are compressed in isolated volatile RAM buffers and immediately streamed directly to your designated Tencent COS bucket. SmallPict NEVER stores, retains, or maintains copies of your original or processed images on its servers.

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 Tencent COS 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

You retain 100% data ownership and sovereignty. You can revoke credentials or rotate keys at any time directly in your Tencent Cloud (COS & Global CDN) console.

Technical FAQ

Frequently Asked Questions

Clear technical answers regarding Tencent Cloud (COS & Global CDN) storage integration, CDN cache headers, security policies, and performance.

1What is Tencent COS + Tencent Cloud Global CDN Integration?

Tencent COS acts as your durable, persistent object repository while Tencent Cloud Global CDN serves cached copies from edge points of presence closest to your viewers. SmallPict acts as the high-speed optimization layer in between, automatically compressing images before storage and edge delivery.

2Can SmallPict optimize images stored in Tencent COS?

Yes. SmallPict connects directly to your Tencent COS buckets. It compresses JPEG, PNG, and WebP assets, converts them into next-generation AVIF and WebP formats, and stores the optimized files directly inside your bucket.

3Does SmallPict work with Tencent Cloud Global CDN?

Yes. When SmallPict streams optimized images to Tencent COS, it attaches optimal HTTP caching headers (Cache-Control: public, max-age=31536000, immutable). Tencent Cloud Global CDN caches these assets at the edge, serving requests with sub-25ms response times.

4Can I use a private Tencent COS 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.

5Does SmallPict require Tencent Cloud (COS & Global CDN) administrative credentials?

No. SmallPict operates on least-privilege principles and only requires credentials (CAM SecretId & SecretKey) with scoped permissions strictly restricted to reading and writing objects within your specific target bucket.

6Can I use a multi-region Tencent COS 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.

7Does 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.

8Where are optimized images stored?

All optimized images are stored directly in your own Tencent COS bucket. SmallPict adheres to a 100% Bring-Your-Own-Storage (BYO) model with zero permanent data retention on SmallPict servers.

9Does SmallPict support WebP and AVIF formats?

Yes. SmallPict natively encodes both AVIF (up to 88% smaller than JPEG) and WebP (up to 75% smaller). When delivered through Tencent Cloud Global CDN, assets are served dynamically according to the visitor's browser support.

10How does caching work after image optimization?

SmallPict injects Cache-Control: public, max-age=31536000, immutable headers into every stored asset. This informs Tencent Cloud Global CDN edge nodes and client browsers to cache the image for up to one year, maximizing cache hit ratios (>99%) and virtually eliminating origin transfer fees.

Zero Egress Shock, Full Infrastructure Control

Deploy SmallPict with Tencent Cloud (COS & Global CDN). Keep your media assets inside your own cloud account while enjoying automated AVIF/WebP encoding and enterprise edge acceleration.
