Free PPTX Converter: No Sign-up, Files Never Uploaded
This free PPTX converter runs entirely on your device. You do not need an account or a login, and your files are never uploaded, so they never leave your browser.
PowerPoint (PPTX) in short. The default PowerPoint format since 2007. A ZIP of XML files for slides, layouts and media.
From PPTX you can convert to PDF, PNG, JPG, TXT and MD. These pairs run on code already in the page, with no extra engine to download. Document-style pairs keep text, headings, lists, tables and images, while complex layouts are simplified.

Converting to PPTX
Pages for converting to PPTX start from PDF and ODP.
Privacy: how it works
- Your PPTX files stay on your device. The page reads each file with the browser's file API, converts it with code running in the tab, and hands the result back as a download. No upload happens, so there is no copy of your file on our servers to protect, delete or leak.
- There is nothing to sign up for and no login. The converter does not ask for an email address, and it does not need to know who you are to do its job.
- You can check the claim yourself: open your browser developer tools, watch the Network tab while a file converts, and you will see no request that carries your file.
Tips
- Check each slide after conversion: animations, transitions and some effects are dropped.
- Use common fonts in the source, since a missing font is replaced.
- Keep the original presentation as the editable master.
- Export to PDF when you only need to share or print the slides.
Frequently asked questions
Is it really free?
Yes. There is no price, no trial, no credit card and no watermark added to your results. Ulkaa Tool does the conversion with your own device, so there is no server bill to pass on to you.
Are my files uploaded?
No. Your PPTX files are read and converted inside your browser and are never sent to Ulkaa or to anyone else. The result is created on your device and you save it from there.
Do I need an account?
No. There is no sign-up and no login. Open the page, add your files and convert. An Ulkaa account is not needed for anything on this tool.
Is there a file size limit?
No limit is set by us. The real limit is your device: the conversion uses your own memory and processor, so very large files can be slow, and a very big batch may need to be split into smaller runs.
What can I convert PPTX files to?
You can convert PPTX to PDF, PNG, JPG, TXT and MD. Pick one on the converter and it applies to every file you add.
Can I convert other files to PPTX?
Yes. PDF and ODP can be converted to PPTX.
Can I convert many PPTX files at once?
Yes. Add as many files as your device can handle. Each one is converted on its own and you can download them one by one or as a single ZIP.
