Who Needs 30KB Assets?
Documentation teams, technical marketers, and product managers use 30KB as a balanced point between readability and speed.
- Knowledge BasesEmbed clean UI walkthroughs in docs, ensuring quick renders on internal networks with strict caching rules.
- App Store ListingsPrepare preview screenshots for Apple App Store and Google Play feature graphics that meet size limits without blur.
- Release HighlightsPromote new features in newsletters or change logs with 30KB illustrations that render correctly in webmail clients.
The 30KB Advantage
Higher detail than 20KB while keeping a safe margin under most CMS thresholds and email client limits.



Prep Once, Publish Everywhere
Follow this workflow to produce consistent 30KB deliverables across products and channels.
- Capture High-DPIUse system tools to capture UI at 2× scale, annotate if needed, then reduce dimensions after compression to stay sharp.
- Add Context CaptionsUse the annotation overlay to add callouts. The tool bakes them into the bitmap while preserving clarity at 30KB.
- Distribute VariantsExport PNG/WebP plus JPG fallbacks for in-app docs, blogs, and PDF manuals from the same compression batch.

30KB Page FAQ
Troubleshooting checkpoints for documentation teams.
How many screenshots can a help article contain?
With 30KB targets you can include 10–12 visuals while keeping the article payload under 400KB.
What about Retina displays?
Export a @2x variant in the batch. Browsers will pick the hi-res version automatically via srcset.
Do annotations affect size?
Minimal; the vector overlay tool rasterizes text crisply without bloating file size when combined with adaptive palette trimming.
Can I automate this?
Yes—use the CLI recipe provided after export to re-run the same compression pipeline in CI.
