Who Needs 30KB Assets?

Documentation teams, technical marketers, and product managers use 30KB as a balanced point between readability and speed.

  • Knowledge Bases
    Embed clean UI walkthroughs in docs, ensuring quick renders on internal networks with strict caching rules.
  • App Store Listings
    Prepare preview screenshots for Apple App Store and Google Play feature graphics that meet size limits without blur.
  • Release Highlights
    Promote new features in newsletters or change logs with 30KB illustrations that render correctly in webmail clients.
Benefits

The 30KB Advantage

Higher detail than 20KB while keeping a safe margin under most CMS thresholds and email client limits.

Maintain legible interface elements like tooltips, dropdowns, and form fields without fuzzy text.

Readable UI Details
CMS-Friendly
Effective Accessibility

Prep Once, Publish Everywhere

Follow this workflow to produce consistent 30KB deliverables across products and channels.

  • Capture High-DPI
    Use system tools to capture UI at 2× scale, annotate if needed, then reduce dimensions after compression to stay sharp.
  • Add Context Captions
    Use the annotation overlay to add callouts. The tool bakes them into the bitmap while preserving clarity at 30KB.
  • Distribute Variants
    Export PNG/WebP plus JPG fallbacks for in-app docs, blogs, and PDF manuals from the same compression batch.

Docs-Focused Feature Set

Build a repeatable pipeline for documentation visuals.

Annotation Layer

Add numbered steps or highlight boxes directly in the compressor before exporting.

CMS Snippet Export

Copy-paste Markdown or HTML blocks prefilled with alt text, captions, and srcset values pointing to your 30KB files.

Version Comparisons

Compare previous release screenshots to spot UI drift before shipping new documentation.

Localization Bundles

Package variants for each locale and automatically append language codes to filenames.

Approval Workflow

Request sign-off from stakeholders with shareable preview links and change tracking.

30KB Page FAQ

Troubleshooting checkpoints for documentation teams.

1

How many screenshots can a help article contain?

With 30KB targets you can include 10–12 visuals while keeping the article payload under 400KB.

2

What about Retina displays?

Export a @2x variant in the batch. Browsers will pick the hi-res version automatically via srcset.

3

Do annotations affect size?

Minimal; the vector overlay tool rasterizes text crisply without bloating file size when combined with adaptive palette trimming.

4

Can I automate this?

Yes—use the CLI recipe provided after export to re-run the same compression pipeline in CI.
