Convert PPTX to BMP
Updated Jul 2026
PPTX is an editable slide deck, and BMP is a flat, uncompressed image format from older Windows software. To convert PPTX to BMP, each slide is rendered as its own picture file. Doing this on your own computer means the deck, and whatever is on those slides, never has to be uploaded anywhere.

How to convert PPTX to BMP
- Open Morphjet and drag in the PPTX file, or a whole folder of decks at once.
- Choose BMP as the output format.
- Convert. Morphjet writes one BMP image per slide next to your original file, and nothing leaves your machine.
PPTX vs BMP: what actually changes
| PPTX | BMP | |
|---|---|---|
| What it holds | Editable slides: text boxes, layouts, speaker notes, animations | One flat picture per slide, no text or layout data |
| File size | Compact for a whole deck | Large, since BMP stores every pixel uncompressed |
| Quality | Sharp at any zoom, since it's built from shapes and text | Fixed resolution, set at the moment you export |
| Opens in | PowerPoint, Keynote, and other presentation software | Almost any image viewer, including very old Windows software |
| Editable | Yes, fully | No, it's a picture now |
| Multiple slides | One file holds the whole deck | One BMP file per slide |
When to convert, and when not to
Convert PPTX to BMP when you need each slide as a plain image, for example to drop into an older Windows program, an install wizard, or embedded software that only reads BMP files.
Keep the PPTX if you still need to edit the deck or present it, since a BMP is just a flat snapshot of how a slide looked at export time.
Why not just use an online converter?
Slide decks often carry the kind of thing you don't want sitting on someone else's server: unreleased pricing, internal roadmaps, client names, financial figures. An online converter has to receive the whole file to rasterize it. Converting on your own computer means those slides are read and turned into images locally, and the deck never travels over the internet.
Questions
Does converting PPTX to BMP lose quality?
Each slide is rendered at a fixed resolution and saved without any compression loss, so the image itself is crisp. What you lose is editability. Text, shapes, and layout become a single flat picture.
Do I get one BMP file or one per slide?
One BMP per slide. A ten-slide deck becomes ten separate image files, each named to match its slide number.
Will speaker notes or animations carry over?
No. BMP only stores a static image, so speaker notes, transitions, and animations don't come across. Only what's visible on the slide is captured.
Why are BMP files so much bigger than the original slides?
BMP stores every pixel uncompressed, with no format-level compression. A single slide rendered at a decent resolution can end up larger than the entire PPTX it came from.
Can I convert a PPTX to BMP without uploading it anywhere?
Yes. A desktop app like Morphjet renders the slides and writes the BMP files on your own computer, so the presentation never has to leave your machine.
Morphjet converts PPTX, BMP, and 1,800+ other formats, all on your machine. Launching this July.
