Use Cases - VIUCraft Image Manipulation API

Product Image Optimization

Problem

Uploading products in dozens of sizes for thumbnails, detail pages, and social sharing creates a maintenance burden and slows page loads.

Solution

Upload once. Request any size on demand via URL. VIUCraft resizes, converts to WebP, and caches — so your CDN serves the right image every time.

# Thumbnail for product listing

# Large image for product detail

https://shop.viucraft.com/resize-1200/quality_q_85/product-abc.webp

# Watermarked for social sharing

Image pipeline

Upload original product photo (once)

Generate thumbnail — /thumbnail-300/

Detail view — /resize-1200/

Social share — /watermark/

Cached and CDN-ready

Media & Publishing

Editorial Image Processing

Problem

Editors upload high-resolution photos that need to be cropped for article headers, mobile thumbnails, and social cards — each with different aspect ratios and dimensions.

Solution

Smart crop automatically finds the most interesting region of each photo and crops it to any ratio you need. No manual editing required.

# Article hero (16:9)

# Responsive thumbnail (4:3)

# Social card (1:1)

https://media.viucraft.com/smartcrop-1200-1200/story-photo.jpg

Responsive image workflow

1 Editor uploads the original high-res photo via the media dashboard.
2 CMS stores the image ID and generates URLs on the fly for each layout slot.
3 VIUCraft smart crops each variant on first request and caches the result.
4 Repeat visitors get cached images — zero processing overhead.
5 Update the crop parameters in the URL any time — no re-upload needed.

Social Platforms

User-Generated Content

Problem

Users upload profile photos and media in unpredictable sizes, formats, and orientations. Displaying them consistently at scale requires a reliable processing pipeline.

Solution

Normalize user uploads at display time. Resize avatars to a fixed square, strip EXIF metadata for privacy, and convert to WebP for fast delivery — all in one URL.

# Avatar (square crop, strip metadata)

# Post image (normalized width)

https://social.viucraft.com/resize-1080/quality_q_80/post-img456.webp

# Blurred preview (low-res placeholder)

https://social.viucraft.com/thumbnail-40/blur-5/post-img456.jpg

UGC processing steps

1 User uploads a profile photo in any format (JPEG, PNG, HEIC, etc.).
2 Your backend stores the raw file and saves the image ID to your database.
3 When rendering the profile, request a square-cropped, metadata-stripped WebP.
4 For feed previews, serve a blurred low-res placeholder while the full image loads.
5 All transformations are cached — user-facing latency stays low.

SaaS Applications

API-Driven Image Pipelines

Problem

SaaS products that handle user documents or assets need a reliable image processing layer that scales automatically without maintaining image processing infrastructure.

Solution

Use the VIUCraft REST API to upload, transform, and manage images programmatically. Webhooks notify your system when uploads complete, enabling fully automated pipelines.

# Upload via REST API

POST /api/v1/images
X-API-Key: your_api_key
→ { "id": "img_abc123" }

# Serve transformed on demand

https://yourapp.viucraft.com/resize-800/convert_fmt_webp/img_abc123.webp

Automated pipeline

1 Your backend calls POST /api/v1/images when a user uploads a document.
2 VIUCraft stores the original and fires a webhook to your callback URL.
3 Your system records the image ID and constructs display URLs on the fly.
4 Cache warming pre-generates the most common variants before users request them.
5 Scale to millions of images — no infrastructure changes required.
