Summary

Adds a new Base64 to Image Converter utility that allows users to paste Base64-encoded image data and instantly see a preview of the decoded image. This is the reverse operation of the existing Image to Base64 converter.

The new utility:

  • Accepts both raw Base64 strings and complete data URIs (e.g., data:image/png;base64,...)
  • Validates input and shows appropriate error messages
  • Displays image preview when valid Base64 image data is provided
  • Includes prominent cross-references to the Image to Base64 converter

Also adds cross-references from the Image to Base64 utility back to this new tool, as users often need both directions.

Updates since last revision

  • Fixed Prettier formatting issue in Base64ToImageSEO.tsx
  • Fixed error message styling to match SVG viewer pattern (changed from mb-4 to mt-6 margins) to prevent layout jumping when error messages appear/disappear
  • CI checks now passing

Review & Testing Checklist for Human

  • Verify layout jumping fix: Test that the error message appearing/disappearing no longer causes the content below to jump. Compare behavior with the SVG viewer (/utilities/svg-viewer) to ensure consistency.
  • Test the Base64 validation logic: The implementation uses regex and atob() to validate Base64 strings. When raw Base64 is provided (without data URI prefix), it defaults to image/png MIME type - verify this works for JPEG, GIF, WebP images as well since browsers typically auto-detect the format.
  • Visually test the new utility: Navigate to /utilities/base64-to-image and test with various Base64-encoded images (PNG, JPEG, etc.) to ensure the preview displays correctly.
  • Verify cross-reference links: Check that the links between Base64 to Image and Image to Base64 utilities work in both directions.
  • Review GitHubContribution username: Currently set to "devin-ai-integration" - may want to change this.

Suggested test plan:

  1. Run npm run dev and navigate to /utilities/base64-to-image
  2. Test with a data URI (e.g., copy output from Image to Base64 converter)
  3. Test with raw Base64 string (without the data:image/... prefix)
  4. Test with invalid input to verify error handling and that layout doesn't jump
  5. Click the cross-reference links to verify navigation
  6. Compare error message styling with /utilities/svg-viewer for consistency
