ODT to BMP Converter

Convert ODT to BMP Online

Render the pages of an OpenDocument Text file into Windows Bitmap (.bmp) images. This is the tool to reach for when a legacy Windows program, an embedded display, or an imaging pipeline insists on raw, uncompressed bitmaps. Each page is rasterized to a flat picture — the text becomes pixels, not selectable characters — and because BMP applies no compression, expect large files compared with PNG or JPG.

How to Convert ODT to BMP

1. Upload Your ODT File: Drag your .odt onto the page or click "+ Add Files". You can queue several documents and convert them with the same settings in one batch.
2. Set the Conversion Quality (DPI): Open Advanced Options and pick a value from the Conversion Quality dropdown — 72 to 1200 DPI, defaulting to 300 (the print-quality balance). DPI is the biggest lever on both sharpness and file size.
3. Set the Background Color or Resolution (Optional): BMP carries no usable transparency, so the Image Transparency / Color control flattens each page onto a solid background (White by default). Use Image Resolution to scale the output by percentage or set an explicit Width and Height.
4. Convert and Download: Click Convert. A single-page document returns one .bmp; a multi-page document returns a ZIP with one BMP per page. No sign-up, no watermark.

BMP vs PNG vs JPG for ODT Pages

All three are flat raster pictures of a rendered page, so none keeps the text editable. The difference is how much disk space the same pixels take.

Only choose BMP when something downstream specifically requires it. For the same lossless quality at a fraction of the size, use ODT to PNG; for a portable, multi-page document with a selectable text layer, use ODT to PDF; to keep editing the words, use ODT to DOCX.

Frequently Asked Questions

Does a multi-page ODT become one BMP or many?

Many. The BMP format holds exactly one image, so each page of your document is rendered to its own bitmap. A one-page ODT downloads as a single .bmp; anything longer downloads as a ZIP with one BMP per page, in document order. To keep every page together in one file, convert to PDF instead.

Why is the BMP so much larger than a PNG of the same page?

Because BMP stores raw, uncompressed pixels while PNG applies lossless compression — for the same content PNG files are commonly 50-80% smaller with no quality difference. In our testing, a text-heavy A4 page at the default 300 DPI lands around 25 MB as a 24-bit BMP but only a few megabytes as PNG. If file size matters and you don't specifically need a bitmap, convert to PNG.

Can I still select or search the text after converting to BMP?

No. Converting a document to BMP rasterizes it — the words become flat pixels rather than characters, so the result is neither selectable nor searchable. Recovering editable text would require OCR. If you need a searchable, portable copy, target PDF; to keep editing the document, use ODT to DOCX.

What DPI should I pick for ODT to BMP?

150 DPI is comfortable for on-screen viewing, 300 DPI (the default) matches print expectations, and 600 DPI is worth it only for reading very fine print. Because BMP is uncompressed, each step up in DPI multiplies the file size — roughly quadrupling it from 300 to 600 DPI — so pick the lowest DPI that still looks sharp for your use.

Is the upload private, and is there a file size limit?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public. There is no fixed page or file-count cap; the practical limit is upload size and your connection speed, since a multi-page ODT renders to several large, uncompressed bitmaps.
