Resolution
Compression

Text, vector graphics, links and forms stay exactly as they are; only images are re-encoded. If a file cannot get smaller, you get the original back.

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.

Sample rate
Channels
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.

Shown by e-readers in the library; leave empty to keep what the document says.

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?

If you continue, the file is uploaded over an encrypted connection and converted on our server. You can keep using the site meanwhile. 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. PPSX is a PowerPoint slide show: opened with a double click, it starts presenting at once instead of opening the editor.

This converter turns your OTP file into PPSX, the right choice for handing out a presentation that should start as a slide show. Every slide, text, picture, shape, table, chart and speaker note is taken over, so you can keep presenting and editing the PPSX file. 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.

Frequently asked questions

How do I convert OTP to PPSX?

Choose or drop your OTP file, keep PPSX as the output and click Convert. After you confirm the upload, our server converts the file and shows the progress; then you download the PPSX file.

Can I convert several OTP files at once?

Yes. Add up to 10 files at a time. Each gets its own background job with its own progress, and you can download each result as soon as it is finished.

How large can the file be?

Each file can be up to 100 MB.

What happens to my file?

It is uploaded only after you confirm. The original is deleted as soon as the conversion is finished, and the PPSX file is kept for 6 hours so you can download it – you can delete it yourself at any time.

Is the OTP to PPSX converter free?

Yes. It is free, without sign-up and without a watermark.

Are animations, notes and fonts kept?

Slides, texts, pictures, tables, charts, speaker notes and most animations and transitions are kept. Fonts that are not installed on our server are replaced by similar ones, and macros or embedded videos can get lost – check the result before presenting.
