All tools › Bytes
Binary file diff
Byte for byte, with the offset and length of every differing run.
It runs entirely in this browser tab: the documents you paste are never uploaded, and the tool makes no network request while it works. Open your browser's network panel and try it — nothing leaves the page.
What it takes
Two runs of bytes — hexadecimal or Base64, or the text itself, whichever the setting names — separated by a line of three dashes.

Settings
- Read the bytes as
- The framework's input is a text area, so binary arrives written down. Choices: Hex, Base64, Plain text.
- Bytes a row
- A number from 4 to 32.
How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Is what I paste uploaded anywhere?
- No. The whole tool is carried as WebAssembly and runs on your own device. That is the point of the group: the files these tools are for are exactly the ones you would not paste into somebody else's server.
- How big a file can it take?
- About a megabyte, and it says so rather than truncating quietly. Past that you are handing it a database rather than a document, and the input here is a text area — the editing view is capped at forty thousand characters and says so, though the tool still reads all of what you gave it.
- Why does it say it guessed?
- Because it did. Which format a document is, which delimiter a table uses and whether the first row is a header are all decided by looking at the text. Each guess is right almost always and each is printed on the result, because a converter that guessed silently and got it wrong would eat a file.
- Does it change my numbers?
- No. A number keeps the text it was written as, all the way through: `1.0` stays `1.0` and a thirty-digit identifier stays thirty digits. Nothing here is ever a floating-point value, which is why a sorted document differs from the original only where you asked it to.
