About formats

TXT

TXT is a plain text file format that stores unformatted character data without any styling or metadata. The TXT format is universally supported by virtually every text editor and operating system, making it the simplest and most portable way to exchange text content. TXT files commonly use the .txt extension and are encoded as ASCII or UTF-8.

Frequently Asked Questions

Is converting TXT to FB2 free?
Yes. This TXT → FB2 converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert TXT to FB2?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my TXT files uploaded to a server?
No. Files never leave your device. The entire TXT → FB2 conversion runs locally in your browser, so your data stays private.
Can I convert multiple TXT files at once?
Yes — batch conversion is supported. Add as many TXT files as you like and convert them to FB2 in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting TXT to FB2 lose quality?
No. FB2 is a lossless format (or used in a lossless mode here), so the original data from your TXT file is preserved bit-for-bit in the converted result.
Does FB2 support transparency from TXT?
Yes. FB2 supports an alpha channel, so any transparent regions of your TXT file will be preserved as transparent in the converted file.
How will the file size change after converting TXT to FB2?
Both formats use comparable compression, so the FB2 output will be similar in size to your TXT file — typically within 10–20% of each other.
