What each format does to your slides
We converted one presentation into every format this tool offers and measured what came out. The source was an 11-slide deck with titles, bulleted text, a data table, coloured shapes and two photographs, so the differences below show what each format actually keeps.
Source: PPTX, 929.8 KB, 11 slides (bulleted text, a table, shapes, two photos)
| Format | Type | Output size | vs source | Output | Keeps | Verdict |
|---|---|---|---|---|---|---|
| PPTX | Editable | 805.3 KB | 87% | 1 file | Everything | The editing default |
| ODP | Editable | 780.7 KB | 84% | 1 file | Everything | Smallest editable deck in our test |
| PPSX | Slideshow | 805.3 KB | 87% | 1 file | Everything | Opens straight into the show |
| POTM | Template | 805.3 KB | 87% | 1 file | Everything | Reusable house style, macros kept |
| PPT | Editable | 1264 KB | 136% | 1 file | Everything | Legacy, and much larger than PPTX |
| PPS | Slideshow | 1264 KB | 136% | 1 file | Everything | Legacy slideshow, same bloat as PPT |
| Fixed | 417.8 KB | 45% | 1 file | Exact appearance | Best for handouts and printing | |
| PNG | Images | 777.1 KB | 84% | 11 files | Appearance only | One file per slide, nothing editable |
| JPG | Images | 721.2 KB | 78% | 11 files | Appearance only | One file per slide, smaller than PNG |
- The modern formats are the efficient ones. PPTX came out at 87% of the source and ODP at 84%, while the legacy PPT grew to 136%. If size matters, avoid the 97-2003 formats.
- PDF was the smallest single file at 417.8 KB, 45% of the source, and it keeps the slide design exactly. The trade is that the slides stop being editable.
- Exporting to images produces one file per slide, not one file: 11 PNGs totalling 777.1 KB, or 11 JPGs at 721.2 KB. Useful for thumbnails and embeds, but nothing stays editable.
- Converting between the editable deck formats is safe. PPTX, ODP, PPSX and the template formats all kept the text, table, shapes and images intact.
Measured with LibreOffice on one representative deck. Your own files will differ, especially with more photographs or embedded video, but the relative ordering holds.
