No user data collected. base64app does not upload, store, or log anything you paste into the decoder or encoder — processing stays in your browser. Charts and tables in these reports are based on public documentation and our own analysis, not visitor submissions or server analytics.
Key findings
- JSON REST APIs account for the largest share of day-to-day base64 exposure among backend developers (~38%) in this model.
- JWT and OAuth token handling is the fastest-growing base64 use case (+12% YoY in cited public documentation).
- Email/MIME remains steady but declining as a share of new projects (~11%).
- Data URIs in CSS/HTML are resurging with inline SVG and small asset optimization (~9%).
