Move text through systems that expect plain characters
Paste UTF-8 text to produce Base64, or paste Base64 to recover the text. The tool handles non-ASCII characters correctly and reports invalid input instead of guessing. Base64 is not encryption: anyone can reverse it. Never paste passwords, private keys, or other secrets into a page you do not control.
How to use this workbench
- Paste your text or load the example.
- Choose any options that apply to your task.
- Read the result, then copy it or download a text file. Your input stays available until you clear it or leave the page.
Frequently asked questions
Does my text leave my browser?
No. Processing happens in a local browser worker. The tool makes no request containing your draft.
Can I upload a document?
Use Import .txt to read a UTF-8 plain-text file locally. Word documents and PDFs are not supported. Copy their text into the input instead. Each field accepts up to 200,000 characters.
Will the result replace my original?
No transformation automatically overwrites your input. Check the output before copying it. Grammar and spelling suggestions change the input only when you choose to apply them.
Make the next edit count
Read the result in context. If the text needs another pass, try the word counter, text cleaner, or readability checker.
