How to Convert BIN to TXT (Read the Text Inside)

You want to convert a BIN file to TXT. Maybe you need to read what is inside. Maybe a support team asked for a text copy. Maybe you want to paste the contents into a document or a forum post.

“BIN to TXT” can mean three different things, and each needs a different method. This guide explains all three in plain words and shows you how to do each one for free, without uploading your file anywhere.

Three ways to turn BIN into text

1. The BIN is already text. It is a text file with the wrong name. You just rename it.
2. You want the readable text hidden inside. You extract the strings, like names, versions and messages.
3. You want every byte written as text. You make a hex dump or a Base64 copy.

Our free BIN file opener handles all three. Let us go through them one by one.

Method 1: The BIN is really a text file

Text files sometimes get saved as .bin. Log files, config files, CSV exports and HTML pages can all end up with the wrong name after a download or transfer.

To check:

1. Drop the file into the BIN file opener.
2. If the type says “Plain text” or “XML document”, it is text.
3. Open the Preview tab to read it.
4. Save it with a .txt extension, or rename it yourself.

Look at the content before you pick an extension. If it has commas between values, it might be a CSV for Excel. If it starts with <html>, it is a web page. If it starts with <?xml, save it as .xml. Choosing the right extension means it opens in the best app.

One common case: a tiny .bin file that turns out to be text with words like “error” or “not found”. That means a download failed, and the server sent an error page instead of the real file. Download it again.

Method 2: Extract the readable text strings

Most binary files, like programs, firmware and game data, contain some plain text mixed in with the binary data. Menus, error messages, model numbers, copyright lines and web addresses are all stored as text.

Pulling these out is called extracting strings. It is one of the most useful things you can do with an unknown file.

1. Open your file in the BIN file opener.
2. Click the “Text strings” tab. You see every readable run of characters, with its position in the file.
3. Set the minimum length. Six is a good start. Raise it to 8 or 12 to hide short random matches.
4. Type in the filter box to search, for example “version” or “http”.
5. To save the whole list, go to “Convert & save” and click “Download strings”. You get a .txt file with one string per line.

Each line in the file starts with the offset in hex, so you can find the same spot again in the hex view. Our guide on reading a binary file explains how the views fit together.

Method 3: Make a hex dump or Base64 text file

Sometimes you need the whole file as text, every single byte. There are two common ways to write binary data as text.

Hex dump

A hex dump writes each byte as two hexadecimal characters, from 00 to FF. It usually has three columns: the offset, the hex bytes and the matching readable characters. People use hex dumps for bug reports, forum questions and documentation, because anyone can read and compare them.

To make one, go to “Convert & save” and click “Download hex dump”. Our tool writes up to the first 16 MB. That covers most firmware files and headers. A hex dump is about four times bigger than the original file, so a full dump of a large disc image would be huge and not useful.

A line of the dump looks like this:

00000000 25 50 44 46 2D 31 2E 37 0A 25 E2 E3 CF D3 0A 31 %PDF-1.7.%.....1

Base64

Base64 turns any bytes into letters, numbers and a few symbols. It is not meant for people to read. It is meant for moving binary data through systems that only accept text, like JSON, email or some web forms.

Click “Download Base64” in the “Convert & save” tab. You get a .txt file you can paste into code. Base64 makes the data about one third bigger. The tool covers the first 50 MB.

Which method should you choose?

• Want to read a log, config or document? Use Method 1.
• Want to know what a program or firmware is? Use Method 2, strings.
• Asked for “the bytes” by a developer or support team? Use Method 3, hex dump.
• Need to embed the file in code or an API request? Use Method 3, Base64.

Doing it with built-in tools

You can also make text versions with tools already on your computer.

Windows PowerShell

• Hex dump: Format-Hex -Path file.bin | Out-File dump.txt
• Base64: certutil -encode file.bin base64.txt

Mac and Linux Terminal

• Hex dump: xxd file.bin > dump.txt
• Strings: strings -n 6 file.bin > strings.txt
• Base64 on Linux: base64 file.bin > base64.txt
• Base64 on Mac: base64 -i file.bin -o base64.txt

These work well, but they do not tell you the file type. Our online bin viewer does that too, and it works on phones.

What about text in other languages?

Our strings view finds plain ASCII text: English letters, numbers and common symbols. Some programs store text in UTF-16, where every letter is followed by a zero byte. In the hex view, this looks like “H.e.l.l.o” in the ASCII column. Windows programs often do this.

For UTF-16 text, the hex view still shows it, just with dots between letters. Command-line tools can handle it too. On Linux, strings -e l file.bin finds little-endian 16-bit strings.

Can you turn a text file back into BIN?

Yes, for hex dumps and Base64. A Base64 file can be decoded back to the exact original bytes. On Windows, run certutil -decode base64.txt file.bin. On Linux, run base64 -d base64.txt > file.bin. A clean hex dump can be turned back with xxd -r on Mac and Linux.

A strings list cannot be turned back. It only holds the readable parts, not the binary data around them.

Real example: checking a firmware version

Imran’s smart camera support team asks him which firmware file he has. He opens fw_update.bin in our tool. The type says “U-Boot firmware image”. He clicks Text strings and types “V” in the filter with a minimum length of 8. A line shows the model number and “V5.6.8 build 230712”. He downloads the strings list as a .txt file and emails it to support. Problem sorted, without sending them the whole firmware file.

Tips for clean text exports

• Raise the minimum string length if the list is full of random short junk.
• Use the filter to find what matters before you export.
• For forums, share only the first few lines of a hex dump, not the whole thing.
• Never share strings or dumps of private files publicly. They can include names, keys or passwords.

Why plain text matters for support requests

Support teams and developers often cannot accept binary attachments. Their ticket systems may block them, and they may not want to open unknown files. A short text export solves both problems. A strings list shows the version and model. A few lines of hex dump show the header. Both paste neatly into a ticket, an email or a chat. They are also easy to search and compare later, which helps when you track a problem across several files.

Frequently asked questions

Can I open a BIN file in Notepad?

You can, but you will see mostly symbols, because Notepad shows every byte as a letter. Use the strings view for the readable parts instead.

Is converting BIN to TXT safe?

Yes. Our tool reads the file in your browser and never uploads it. Making text exports does not change your original file.

Why is my hex dump so big?

Each byte becomes about three characters plus spaces and the text column. A 1 MB file makes a dump of about 4 MB.

Can I convert a BIN to Word or Excel?

If the BIN is really a Word or Excel file, our tool shows it as a ZIP archive. Save it as .docx or .xlsx. If it is plain text with commas, save it as .csv and open it in Excel.

Conclusion

Turning a BIN into text depends on what you need. If the file is already text, rename it. If you want the readable parts, extract strings. If you need every byte, make a hex dump or Base64 copy. Our free BIN file opener does all three in your browser. Next, learn how to read the bytes themselves in how to view a binary file.
