Output
Worksheets
Separator

Columns are found from how the text lines up. Clear tables work best; check merged cells and headers after converting.

Fonts are replaced by Word’s standard font; complex layouts (columns, text boxes) become simple paragraphs you can edit.

Slide quality

Each page becomes one slide that looks exactly like the PDF. The text in the notes can be copied into your own slides.

Text layout

The first time, the engine and language data (about 2–8 MB) are downloaded from this site; after that it runs on your device.

Video

Lower resolutions reduce file size. The video will not be enlarged.

Lower values mean higher quality and larger files. Applies to H.264, VP9, MPEG-4 and MPEG-2 outputs.

Choose a video encoder supported by the output format.

Subtitle tracks are embedded in the video. Burning makes text permanent in the picture.

PNG, JPEG or WebP up to 5 MB. The logo is placed at 25% of the video width.

Choose an audio codec supported by the output format.

Audio
Bitrate

Higher means better sound and a larger file. “Auto” keeps the bitrate of the original (at least 128 kbit/s); from lossless files it uses the format’s high-quality setting.

Cut (optional)

Times such as 1:30 or 0:45.5. Leave empty to keep the whole recording.

Picture

The video shows this picture for the whole length of the sound – for example to upload music or a podcast to YouTube.

Pages to convert

Several pages arrive as a ZIP with one image per page.

PDF/A-2b embeds all fonts so the file looks the same in many years; required by many courts and public offices.

Scales every sheet so it fits on a single page instead of being split across several.

Sheets

CSV and TSV hold one table: with “Every sheet” each sheet becomes its own file, together in a ZIP.

Separator

Excel in many European languages expects a semicolon; most other programs a comma.

Convert on our server?

The original is deleted as soon as it is converted; the result is kept for 6 hours so you can download it, and you can delete it at any time. Files are never shared or used for anything else.

About this tool

OTP is the OpenDocument presentation template format. AVIF is a modern image format with very small files at high quality.

This converter turns your OTP file into AVIF, the right choice for very small page images for modern websites. Every slide becomes one AVIF picture (150 DPI by default); several pictures arrive as a ZIP. Under “Options” you can choose the resolution or only the first slide. Add up to 10 files at once – each one is converted in the background, so you can keep using the site and download every result as soon as it is ready.

Presentations are converted on our server: the upload starts only after you confirm, the original is deleted after conversion and the result is kept for 6 hours unless you delete it sooner.
