ODT to AVIF Converter

ODT to AVIF — Is AVIF the Right Image Format for a Document Page?

An ODT is an editable OpenDocument Text file. AVIF is a still-image format. So this conversion is not a translation of your words — it rasterizes each page of the document, baking the text, fonts and layout into flat pixels, and writes one AVIF per page. The short answer on format choice: pick AVIF when the page images are headed for a web page or an app and you want the smallest file that still looks clean; pick PNG when the page is dense body text that must stay pixel-sharp, and PDF when you actually wanted the whole document in one file with the text still selectable.

AVIF vs PNG vs JPG for a Rendered ODT Page

The figures below come from one real measurement: a US Letter page of body text, a footnote, a hyperlink and a small table, rendered at the default 300 DPI (2,550 × 3,300 pixels) and then encoded four ways through the same pipeline this page uses.

When to Pick AVIF

• The page images will be embedded in a web page or a modern app, where 94.7% browser coverage is plenty and bytes on the wire matter.
• The page carries screenshots, charts, coloured headers or a photo — AVIF's AV1 intra coding handles tonal content far better than a palette format.
• You are producing a lot of pages at once and the cumulative download size matters more than absolute per-glyph sharpness.
• You want one modern, royalty-free format instead of maintaining both a JPG and a WebP variant.

When to Pick PNG, JPG or PDF Instead

• Dense body text at small point sizes: every lossy codec, AVIF included, spends its bits on the busiest areas. ODT to PNG keeps glyph edges exact.
• A recipient on old desktop software: a colleague opening the file in a legacy image viewer may get nothing at all. ODT to JPG opens everywhere with zero setup.
• You wanted the document, not a picture of it: ODT to PDF keeps every page in one file with the text still selectable and searchable.
• You need it to keep being editable: convert to ODT to DOCX instead — an image can never be edited back into a document without OCR.

How to Convert ODT to AVIF

1. Upload Your ODT File: Drag your .odt onto the page or click "+ Add Files" to browse. Several documents can be queued and converted in one batch with the same settings.
2. Set Conversion Quality (DPI): This dropdown is the render resolution for the page, not a compression slider, and it is the single biggest lever on both sharpness and size. It offers 72, 96, 150, 200, 300 (preselected), 400, 600 and 1200 DPI.
3. Choose Image Compression and the Background Colour: Under Image Compression, either leave the Quality Preset on "Very High (Recommended)" or switch to "Specific file size" and type a byte target. Under Image Transparency, the Colour dropdown fills the page background — White is preselected.
4. Convert and Download: Click Convert. A one-page document downloads as a single .avif; a longer document produces one AVIF per page, and a "Download All (Zip)" button appears to fetch them together. No sign-up, no watermark.

What Conversion Quality (DPI) Actually Costs

DPI sets how many pixels the renderer paints per inch of page, so the pixel count grows with the square of the setting. AVIF's file size does not — a page of black-on-white text stays highly compressible as it gets bigger, which is why 600 DPI is only about 1.8× the bytes of 300 DPI despite having four times as many pixels.

Frequently Asked Questions

Does a multi-page ODT become one AVIF file?

No. AVIF holds a single still image, so each page is rendered separately and written as its own file — a 5-page document gives you 5 AVIFs in page order, with a "Download All (Zip)" button to collect them. There is no way to stack pages into one scrollable AVIF. If a single file containing every page is what you need, convert to ODT to PDF instead.

Will the text still be selectable or searchable in the AVIF?

No, and that is inherent to the conversion rather than a limitation of this tool. Rasterizing paints the glyphs into a pixel grid; there is no text layer left to select, copy, search or reflow. That is often exactly what people want — an image looks identical in every viewer and cannot be accidentally edited. If you need the words back you would have to run OCR on the image, so keep the original .odt, or convert it to DOCX if you want to carry on editing.

Is AVIF supported widely enough to send to other people?

On the web, comfortably: caniuse puts AVIF at 94.7% of global users, covering Chrome from version 85, Firefox from 93, Safari from 16.4 (so iOS 16 and later) and Edge from 121. The weak spot is outside the browser — some older desktop image viewers and OS previewers still need an extra codec before they will open an .avif. If you are emailing page images to an unknown recipient rather than publishing them, JPG removes that risk entirely.

Which quality preset should I choose for a page of text?

Start with "Very High (Recommended)", the preselected one. Text is unusually unforgiving of lossy compression because a glyph is mostly high-contrast edges, and the presets step down fairly quickly: Highest, Very High, High, Medium, Low, Very Low and Lowest map onto progressively more aggressive quality targets. In practice the visible failure mode is a faint grey wash creeping into the whitespace around small letters. Drop to Medium only if you have checked the result at 100% zoom.

Can I make the AVIF hit a specific file size?

Yes — that is what the "Specific file size" mode in the Image Compression group is for. Enter a number and pick Bytes, Kilobytes or Megabytes, and the server encodes the page, measures the result, and searches for the quality value that lands under your target, optionally scaling the resolution down as well if you tick Auto Scale. Note that the target applies per page image, not to the whole set: a 10-page document with a 200 KB target produces ten files of roughly 200 KB each.

Why is my AVIF page white — can it have a transparent or coloured background?

A rendered word-processing page is opaque, so there is nothing transparent to preserve. The Image Transparency group's Colour dropdown decides what fills the page area, and White is preselected because that matches a printed sheet. You can pick any of the other 24 named colours if the image will sit on a coloured surface. AVIF itself does support an alpha channel; there simply isn't any alpha in a document render for it to carry.

How is AVIF different from HEIC, and which should I use?

They are close cousins: both wrap image data in the HEIF container built on the ISO Base Media File Format, and both descend from video codecs. The difference is which codec. AVIF carries an AV1 intra frame and is royalty-free from the Alliance for Open Media; HEIC carries an HEVC (H.265) frame and is the format Apple ships. That licensing split decides the reach: AVIF decodes in Chrome, Firefox, Edge and Safari, while HEIC is limited to Safari 17+ and Apple's own apps at roughly 15% of users. On the same test page AVIF came out smaller too — 138 KB against 221 KB. For anything not exclusively Apple, AVIF is the better target.

What happens to my ODT file after the conversion?

It is uploaded over an encrypted connection, converted on our servers — LibreOffice lays the document out, the pages are rasterized at your chosen DPI, and each page is encoded to AVIF — and then deleted automatically after a few hours. No sign-up, no watermark, and nothing is shared or made public. There is no fixed page-count cap; the practical limit on a very large document is upload size and connection speed.
