Format playbook
Compare PNG / JPEG / WebP / AVIF across transparency, animation, and compression, then follow the decision checklist.

A knowledge tree from concept to delivery
Follow this tree to evaluate assets, pick the right format, decide on encoding, and ship optimized files. ImgEasyResize gives you the tools to walk through each branch until the experience is both sharp and lightweight.
Source preparation Source Layer
-
Origin & color space
Check whether the image comes from RAW, a screenshot, or a design comp, and note its color space (sRGB / Display P3) to anticipate contrast shifts.
-
Framing & target size
Decide on crop ratios, final display sizes, and fallback Retina scales. ImgEasyResize makes those decisions concrete with live previews.
-
Motion or still?
Still images usually land on JPEG / WebP / AVIF. If you need transparency or pixel-perfect art, PNG or lossless WebP is a safer fit.
Formats & encoding Processing Layer
-
Pick the primary format
Balance browser support and file size across JPEG, PNG, WebP, or AVIF. When in doubt, export a modern format plus a fallback.
-
Quality & compression
Tune quality sliders, switch between lossy / lossless, and pair them with the final width and height to keep fidelity while trimming bytes.
-
Experiment & batch
Before shipping, batch-export variations, keep filenames tidy, and log results so stakeholders can compare settings objectively.
Delivery & monitoring Delivery Layer
-
Loading strategy
Combine lazy-loading, responsive
srcset/sizes, and CDN compression so every device receives the most efficient asset. -
Encoding & security
When embedding Base64 or sprites, weigh bundle size, cache behavior, and CSP rules to protect your origin.
-
Measure impact
Use Core Web Vitals, Lighthouse, or your own bandwidth monitors to prove that your compression choices improved speed.

Document your recurring steps—crop, rename, batch export—so teammates can repeat the exact checklist.
- Track input sources and target outputs
- Lean on batch download to preserve filenames
- File sample outputs for side-by-side comparisons
What to try next
Pick a small image set and walk through the tree: crop and export in ImgEasyResize, then compare settings against the format and encoding pages to build your own best-practice notes.
