Frequently Asked Questions

Is converting POTX to PPTX free?

Yes. This POTX → PPTX 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 POTX to PPTX?

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 POTX files uploaded to a server?

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

Can I convert multiple POTX files at once?

Yes — batch conversion is supported. Add as many POTX files as you like and convert them to PPTX 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 POTX to PPTX lose quality?

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

Will transparency be preserved when converting POTX to PPTX?

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

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

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