PNG – Portable Network Graphics
PNG stores images with lossless compression and supports full transparency, which makes it the usual choice for logos, screenshots and graphics with sharp edges. The trade-off is size: a photograph saved as PNG is normally far larger than the same photo saved as JPG or WebP.

Frequently asked questions
How do I convert POTX to PNG?
Click Select File or drop your POTX file onto the upload box. The converted PNG appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
