PPSX

PPSX is a Microsoft PowerPoint Slide Show format that opens directly in slide-show (read-only presentation) mode rather than editing mode. PPSX is structured identically to PPTX, but the .ppsx extension signals that the file is intended to be displayed, not edited. PPSX is used for distributing finished PowerPoint presentations.

Frequently Asked Questions

Is converting PPSX to POTX free?

Yes. This PPSX → POTX converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert PPSX to POTX?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my PPSX files uploaded to a server?

No. Files never leave your device. The entire PPSX → POTX conversion runs locally in your browser, so your data stays private.

Can I convert multiple PPSX files at once?

Yes — batch conversion is supported. Add as many PPSX files as you like and convert them to POTX in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting PPSX to POTX lose quality?

No. POTX is a lossless format (or used in a lossless mode here), so the original data from your PPSX file is preserved bit-for-bit in the converted result.

Will transparency be preserved when converting PPSX to POTX?

Yes. Both PPSX and POTX support alpha-channel transparency, so transparent areas of your file are kept unchanged in the POTX output.

How will the file size change after converting PPSX to POTX?

Both formats use comparable compression, so the POTX output will be similar in size to your PPSX file — typically within 10–20% of each other.
