Frequently Asked Questions
What is a PPTX file?▼
PPTX is the PowerPoint presentation format — slides with text, images, charts, and animations. It is the standard for business presentations and lectures.
Why convert PPTX to PDF?▼
PDF preserves your slides exactly for sharing — recipients cannot accidentally edit layouts or fonts, and the file opens on any device without PowerPoint installed.
Can I convert a PPTX to images?▼
Yes. Converting slides to PNG or JPG lets you drop them into documents, social posts, or websites, each slide as a clean, individually usable image.
Will converting PPTX keep my animations?▼
PDF and images are static, so animations and transitions are flattened. If you need an editable copy, keep the PPTX original.
Are my presentations uploaded when converting?▼
No — conversion happens locally in your browser. Client decks and unreleased slides stay on your device.
