Free online TXT to AVI converter

An AVI-only player or editing workflow may require a document to be delivered as video. Since a TXT file has no pages or video frames, conversion renders its contents as timed page images.

What the TXT format is

TXT is plain text: it stores characters and line breaks, but not fixed page layout, fonts, images, or video. Text editors, code editors, and word processors can create or open TXT files; the same file may wrap differently depending on the program and display settings.

What the AVI format is

AVI is a video container that can hold video and audio streams. It is supported by many desktop players and editing tools, but compatibility depends on the video codec inside the file. A TXT-to-AVI conversion typically turns each rendered page into a still frame displayed for a set time; it does not create narration or motion.

How to convert TXT to AVI

Online on 101convert.com

1. Upload the TXT file on the 101convert.com converter page. Multiple files can be added for batch conversion; the page shows the per-file size limit.
2. Set show each page for to choose how long each page appears.
3. Convert the file, then download the resulting AVI.

Offline with desktop software

A free workflow uses LibreOffice Writer to lay out the text and export a PDF, Poppler to render PDF pages as images, and FFmpeg to encode those images as AVI. These tools are available for Windows, macOS, and Linux, though installation methods vary.

1. Open the TXT file in LibreOffice Writer using File → Open. Choose the font, page size, and margins, and add page breaks if needed. Export with File → Export As → Export as PDF, for example as input.pdf.
2. In a terminal opened in the folder containing the PDF, render its pages to PNG files at 150 dpi:
   pdftoppm -png -r 150 input.pdf page
   This creates files such as page-1.png and page-2.png.
3. Encode the page images as a video, with each page displayed for five seconds:
   ffmpeg -framerate 1/5 -start_number 1 -i page-%d.png -c:v mpeg4 -q:v 5 -pix_fmt yuv420p output.avi

Quality and compatibility

Page layout determines readability: choose a font size and margins that keep lines from becoming too small, and check the rendered PDF before encoding. In the FFmpeg command, mpeg4 selects the video codec and yuv420p improves playback compatibility with common players; AVI itself does not guarantee support for every codec.
