關於 Base64Encoding

Base64Encoding is a free toolbox for everything related to Base64: converters for text, images, audio, video, PDFs and arbitrary files, validators and repair tools, and practical guides for developers.

We also ship private everyday utilities people search for worldwide — PDF, QR, hashtags, regional IDs, e-invoices — always with Base64-grade privacy: process in the browser, no upload by default.

Our principles

• Privacy first. Conversions run locally in your browser. We do not upload, store or inspect the data you convert.
• Correctness. Every standard, padding rule and character set is implemented carefully and tested. When input is broken, we explain exactly why.
• Speed. Pages are static, lightweight and served from a global CDN.
• Free forever. The site is funded by non-intrusive advertising. There are no sign-ups, no limits and no paywalls.
• Built for every language. Tools, guides and trust pages are available in dozens of languages so searchers find a local, useful answer.
