What is a PPT file?
PPT is the older binary file format that presentation software used to save slideshows, common from the 1990s through the mid 2000s. It stores slides, text, images, and formatting in one file, so nothing about the layout is lost. It's since been replaced by the newer PPTX format, so a PPT file usually means an older presentation.

Why PPT exists
PPT was the default file format for presentation software for years, before the newer PPTX format took over in 2007. It's a binary file, structured in a way built for one specific program to read, which is part of why it doesn't share as easily with newer software or the web as PPTX does.
In plain terms, a PPT file bundles everything about a slideshow, the text boxes, the images, the transitions, the embedded fonts, into a single package. That's what makes it lossless: reopen it later and the slides look the same as they did when you saved them.
Most people run into PPT files today because they're old: a training deck from a previous job, a template someone built years ago, an archived pitch deck nobody updated. Current presentation software can usually open them, but sometimes flags them for conversion, and some tools or web uploaders expect PPTX and don't handle PPT cleanly.
The trade-offs
Strengths
- Preserves slide layout, fonts, and formatting exactly as saved
- Still opens in most current presentation software
- Single self-contained file, no extra folders or parts
Watch-outs
- Older binary format, less compatible with other software than PPTX
- Larger file size than the newer PPTX format for similar content
- Some modern tools and web uploaders expect PPTX and reject or mishandle PPT
A note on privacy
A PPT file can carry hidden metadata, including the author's name, the company it was made under, and notes left in speaker comments. If you convert it with an online tool, that file and everything embedded in it gets uploaded to someone else's server first. Converting it on your own computer keeps the presentation, and whatever details are buried in it, on your machine.

Questions
How do I open a PPT file?
Most current presentation software on Mac and Windows opens PPT files directly. If yours doesn't, converting it to PPTX or PDF usually solves the problem.
Is PPT better than PPTX?
Not really. PPTX is newer, smaller, and better supported by current software. PPT still opens fine for older files, but there's no real reason to choose it over PPTX for anything new.
Why do I still have old PPT files?
Anything saved before presentation software switched to PPTX around 2007 was saved as PPT by default. Old training decks, templates, and archived pitch decks are the usual reason they're still around.
Can I convert a PPT file without uploading it?
Yes. A desktop app like Morphjet converts PPT files on your own computer, so the presentation and any personal details in its metadata stay off the internet.
Morphjet opens and converts PPT, one of 2,748 conversions it runs on your own computer. Available now.
