Frequently Asked Questions

Is converting PPTX to POTX free?

Yes. This PPTX → 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 PPTX 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 PPTX files uploaded to a server?

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

Can I convert multiple PPTX files at once?

Yes — batch conversion is supported. Add as many PPTX 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 PPTX to POTX lose quality?

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

Will transparency be preserved when converting PPTX to POTX?

Yes. Both PPTX 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 PPTX to POTX?

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