Free online ODT to PNG converter

Source format: ODT

ODT is the OpenDocument Text format, the standard word-processing file used by LibreOffice, Apache OpenOffice, and other office suites that support the OpenDocument standard. It is commonly used for letters, reports, forms, manuals, and other editable documents. Because ODT is a document format, it stores text, styles, images, tables, and layout information rather than a fixed visual snapshot.

Target format: PNG

PNG is a lossless raster image format widely used for screenshots, web graphics, diagrams, and images that need sharp text or transparent backgrounds. Compared with document formats, PNG is fixed-size and image-based, so it is useful when you want to preserve the exact visual appearance of a page as an image. PNG is especially good for sharing a document page as a picture, embedding it in presentations, or posting it online.

How to convert ODT to PNG

Converting ODT to PNG usually means rendering each page of the document as an image. This is not a true document-to-document conversion; it creates a flat picture of the page, so the result is no longer editable text.

The most reliable desktop workflow is to use LibreOffice to open the ODT file and export it to PDF first, then render the PDF pages to PNG. If you want a quick no-install option, you can also convert the file on 101convert.com for free.

Method 1: LibreOffice and a PDF-to-PNG step

1. Open the ODT file in LibreOffice Writer.
2. Check the page size, margins, and layout, because the PNG output will reflect the document’s page appearance.
3. Choose File → Export As → Export as PDF and save the document as a PDF.
4. Render the PDF pages to PNG with a local tool such as ImageMagick or Poppler utilities.
5. For example, with ImageMagick, you can use magick -density 300 input.pdf output.png to create high-resolution PNG images.

If the PDF has multiple pages, the converter will usually create one PNG per page, often with numbered filenames.

Method 2: Batch conversion with LibreOffice headless mode

For automated workflows, you can convert ODT to PDF using LibreOffice headless mode, then render the PDF to PNG in a second step. A common command is soffice --headless --convert-to pdf input.odt, followed by a PDF-to-PNG render command. This is useful for batch processing many documents.

Method 3: Convert on 101convert.com

1. Upload the ODT file to the 101convert.com converter.
2. Start the conversion, then download the resulting image file (s).

Quality and limitations

PNG output depends on rendering resolution. A low-resolution export can make text look blurry, while a higher resolution, such as 300 DPI or more, usually produces sharper results. Higher resolution also increases file size.

Complex ODT features such as embedded fonts, transparency, footnotes, headers, and page numbering are generally preserved visually if the rendering engine supports them, but exact appearance can vary slightly between office suites and converters. If the document contains unusual fonts or advanced layout elements, test the output before using it for publication.

Because PNG is a raster format, it is best for single-page previews, screenshots, and sharing a page image. If you need an editable or compact document, keep the file in ODT or convert it to PDF instead.

When to use this conversion

ODT to PNG is useful when you need a static image of a page for a presentation, a website, a preview, or a social post. It is less suitable for long documents, because multi-page files usually become multiple PNG images and can be large.
