Overview
Image optimization is more than making files smaller. When assessing delivery with WAFGO, consider visual quality, display size, cache reuse and processing costs together.
This is an image-processing and delivery cost guide, not an unlimited-transformation offer. Confirm processing availability, formats and rates for the actual solution.
Understand how image variants are produced
One source image can produce many sizes, formats and crops. Without bounded specifications, even a small source library can create a large processing and caching workload.
Source-image count
Measure additions, replacements and bulk imports, separating total library size from monthly changes.
Variant specifications
Define a bounded set of widths and crops for common layouts to avoid fragmented caches from arbitrary variants.
Format and quality
Choose outputs based on client support and visual requirements rather than promising one compression ratio for every image.
Align scope before comparing charging methods
Per-site, processing-based, variant-based and transfer-based pricing can cover different costs. Confirm how initial processing, repeated requests, cache expiry and reprocessing are measured.
| Possible dimension | Boundary to check |
|---|---|
| Site or billing period | Domain count, variant limits, resource allowances and overages |
| Processing or transformation count | Treatment of initial generation, repeat processing and failures |
| Storage and transfer | Separate charges for originals, variants and CDN delivery |
| Bulk migration | Historical-library processing, cleanup and regeneration |
Validate benefits with representative images
Test product details, portraits, screenshots, transparency and large backgrounds. Transfer savings matter only when image quality and layout remain correct.
- Retain originals and a fallback, checking that crops preserve important details.
- Record output sizes, quality, processing latency and cache behavior.
- Use approved variants and assess new dimensions before launching a redesigned theme.
Implementation & checks
- 01
List display contexts
Identify listing, detail, avatar and background images.
- 02
Bound the variants
Agree on sizes, crops, formats and quality.
- 03
Measure and review
Use real library samples to review quality and cost.
