Frequently asked questions

Is PDFwerk really free?

Yes. All tools work without an account and without limits. The site is funded by ads.

Are my files uploaded?

No. Processing happens entirely in your browser. Your documents are never sent to a server or stored anywhere.

Does it work on my phone?

Yes, in every current browser on phones, tablets and computers. Very large files are faster on a computer.

How much does compression shrink a PDF?

Scanned documents and image-heavy files often shrink by 50 to 90 %. Pages are re-saved as images, so text can no longer be selected afterwards.

PowerPoint to PDF

Save PPTX presentations as PDF – every slide becomes one page.

    Animations, videos and embedded charts are not included. Fonts missing on your device are replaced with similar ones.

    How to convert PowerPoint to PDF

    1. Choose your PPTX file.
    2. Click “Convert”. The slides are drawn one after another.
    3. Download the PDF – in the same page format as your presentation.

    Ideal for sharing lecture slides, talks or handouts without the recipient needing PowerPoint. Text, bullet points, shapes, images, tables and backgrounds are kept; animations and transitions don’t exist in a PDF anyway.

    Frequently asked questions

    Are old .ppt files supported?

    No, only .pptx. You can save older .ppt files as .pptx in PowerPoint, Keynote or LibreOffice.

    Does the PDF look exactly like the presentation?

    For most slides, very close. Embedded charts, SmartArt, videos and rare fonts are simplified or replaced with similar ones.

    Can I select the text in the PDF?

    No, each slide is saved as an image. In return it looks the same on every device.
