Slides, modernised
Old binary .ppt decks open in compatibility mode at best. PPTX is smaller, safer and works with PowerPoint, Google Slides, Keynote and LibreOffice.
PDF option built in
Sending the deck rather than editing it? Choose PDF and every recipient sees identical slides — no fonts required.
Private & secure
Uploaded over HTTPS, processed on EU servers, never shared with third parties, and permanently deleted after 1 hour. Never used to train AI.

How it works

1
Upload your PPT
Drag and drop the .ppt presentation, or click to browse.
2
Pick PPTX or PDF
PPTX keeps the deck editable; PDF locks it for clean sharing.
3
Download the result
Ready in seconds — the download link is valid for 15 minutes.

Common questions

Will animations and transitions survive?

Slide content — text, layouts, images, charts, speaker notes — converts faithfully. Simple transitions usually carry over; complex custom animations may simplify. For pixel-perfect delivery, export the PDF.

Why not keep using the old .ppt?

Google Slides, many LMS platforms and newer Office builds increasingly refuse the 1997 binary format. PPTX is also roughly half the size and far less corruption-prone.

Can you convert PPT directly to video or images?

Not yet — today the outputs are PPTX and PDF. If you need slides as images, convert to PDF here, then use the PDF-to-JPG tool on the result.

Is there a file size limit?

Free users can convert files up to 25 MB without an account. Pro raises that to 500 MB per file with 3,000 credits a month; Business goes to 5 GB.
