Free, client-side image to Base64 tools for developers.

What It Does

• Convert PNG, JPG, SVG, WebP and GIF images to Base64 data URIs.
• Decode Base64 image strings back into previewable, downloadable images.
• Copy ready-to-use raw Base64, data URI, HTML <img> and CSS snippets.
• Run entirely in the browser with the FileReader API. No upload, no sign-up.

Local Preview

python3 -m http.server 8000

Then open http://localhost:8000.

Deploy（生产 = Worker image2base64，不是 Pages）

自定义域挂在 Workers domain image2base64.com。改完后：

rsync -a --delete \
  --exclude '.git' --exclude 'dist' --exclude '.claude' --exclude '.wrangler' \
  --exclude 'worker.js' --exclude 'wrangler.toml' --exclude '.assetsignore' \
  --exclude 'check_seo_consistency.py' --exclude 'SEO_LOG.md' --exclude 'README.md' \
  --exclude '_会话交接*' --exclude '.gitignore' --exclude '.DS_Store' --exclude 'LICENSE' \
  ./ dist/
npx wrangler deploy

301 写在 worker.js（/jpeg-to-base64→/jpg-to-base64，/base64-to-jpeg→/base64-to-jpg）。Pages 项目仅作旁路预览。

SEO consistency check

Deterministic scan (unique H1 / canonical / sitemap ↔ disk):

python3 check_seo_consistency.py

Exit 0 = no FAIL（WARN 例如 jpeg→jpg 合并仍算通过）。--json 可出机器可读报告。
