What the Base64 Text Encoder does
Base64 Text Encoder: transforms Base64 from Plain text.
Base64, derived from Plain text. You can nudge a single number and watch the effect straight away.
Most people who open the Base64 Text Encoder are writers cleaning up a draft. Consistent formatting is the difference between a draft and something publishable.
This runs client-side, which means we never receive what you enter and could not retrieve it if asked.
If you want to check the arithmetic, the field table, the method and a worked example are further down.
What do the Base64 Text Encoder fields mean?
The Base64 Text Encoder uses 1 input. You do not have to fill everything in before seeing an answer; the starting values already produce one.
| Field | What to enter | Default |
|---|---|---|
| Plain text | paste or type any amount of text | The quick brown fox jumps over the lazy dog. Pack my box with five dozen liquor jugs. |
How does the Base64 Text Encoder work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same transformation.
Values are checked first: an out-of-range or non-numeric entry names the offending field instead of returning nonsense.
Worked example
These are the values the Base64 Text Encoder loads by default, and the result it produces from them. This is the worked example the page starts from, reproduced here so you can check the arithmetic.
| Plain text | The quick brown fox jumps over the lazy dog. Pack my box … |

How to use it
- Paste your content into Plain text.
- Watch the results panel as you type: it recalculates on every keystroke.
- The panel reports Base64.
- Copy Link puts the current inputs in the URL, so bookmarking it brings the same numbers back.
What this tool does not do
- Word and character definitions vary between tools: this one counts whitespace-separated tokens.
- It does not account for anything you did not enter, by definition.
Frequently asked questions
You need Plain text. Every box already holds a working value, meaning you can explore the calculation before committing to real figures.
With the values loaded when the page opens, base64 comes out as VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wcyBvdmVyIHRoZSBsYXp5IGRvZy4gUGFjayBteSBib3ggd2l0aCBmaXZlIGRvemVuIGxpcXVvciBqdWdzLg==. The figure is derived from the inputs above, so it updates whenever they do.
No. Your text stays in the browser, safe for drafts, private notes or anything unpublished.
No. There is no account, no usage cap and no trial period. The site is funded by advertising rather than by charging for the tools.
The transformation is exact for the method described above. Where a value is rounded for display, the underlying figure keeps full precision.
