About Merge PowerPoint
Combines two or more PowerPoint presentations (.pptx) into one. By default the result stays editable: every slide keeps its text, notes, charts and tables, and each deck keeps its own slide master, layouts and theme, so slides from different decks keep the look they came with (PowerPoint supports several masters in one file). Pictures, charts and layouts that have the same file name in two decks are kept apart, so nothing is overwritten. If you would rather have one flat deck, "Merge as pictures" turns every slide into a picture; that is not editable, but it works for decks of any size.
All decks must have the same slide size as the first one (for example all widescreen 16:9); different sizes cannot be merged as editable slides without distorting them, so use Merge as pictures for those. "Use the first deck's design" is offered only when every layout in the other decks has a layout with the same name in the first deck. Comments in the second and later decks are left out, their embedded fonts are not carried over, and their notes pages use the first deck's notes master. Old .ppt files: open them in PowerPoint and save as .pptx first.
- Does the merged deck keep each deck’s design?
- Yes. By default every deck keeps its own slide master, layouts and theme, which PowerPoint supports in one file, so slides from different decks look the way they did. Pictures, layouts and other parts with the same file name in two decks are kept apart, so nothing is overwritten. If every layout of the later decks has a layout with the same name in the first deck, you can also choose to put all slides on the first deck’s design.
- Why does it say my decks cannot be merged as editable slides?
- Slides only look right at the slide size they were made for. If the decks have different sizes, for example one widescreen and one 4:3, putting them in one file would stretch or crop the slides, so the tool does not do it and says which deck differs. Merge as pictures works for any sizes, or you can change the slide size in PowerPoint first.
- What is Merge as pictures?
- Every slide of every deck is drawn to a picture and the pictures become one slide each. The result looks like the slides but nothing in it is editable: no text, notes, links or charts. It is the fallback for decks that cannot be merged as editable slides, and a way to make one flat deck.
- What is left out when decks are merged as editable slides?
- Comments in the second and later decks, because their authors would collide with the first deck’s. Fonts embedded in the later decks are not carried over, so a font missing on the computer is replaced. The later decks’ notes pages use the first deck’s notes master. The result page lists what applied to your files.
- Is my presentation uploaded anywhere?
- No. Each deck is read and the merged file is built in your browser tab; nothing is sent to a server.
How to use Merge PowerPoint
Drop two or more .pptx files and put them in the order you want with the arrows; the first deck sets the slide size. Each deck shows its first slide, its slide count and what it carries, and Preview slides opens it. Choose Editable slides, which keeps each deck’s own design, or Merge as pictures. For editable slides you can tick Use the first deck’s design when the tool says it is possible. Press Merge, then check the merged deck slide by slide in the preview before you download.
When to use it
Useful when a presentation is built by several people, when a monthly report is made of one deck per team, when slides from an old deck should be added to a new one, or when you want a template’s opening and closing slides around your own. Because each deck keeps its own master, you can combine decks without reformatting anything.
When not to use it
If the decks have different slide sizes, editable merge is refused and Merge as pictures is the only option here; or change the size in PowerPoint first. If you only want a few slides from one deck, use Split PowerPoint on it first. If you want one design throughout and the layouts do not match by name, merge, then apply the design in PowerPoint with Design, then Slide Master tools.
Tips for best results
Put the deck whose look you want to win first and try Use the first deck’s design. Check the preview of the merged deck for fonts: a font used in one deck but missing on your computer is replaced. If the merged file is large, run Compress PowerPoint on it afterwards. If a deck refuses to merge, the message names the deck and the reason.
Limitations
All decks must have the first deck’s slide size. Comments in the later decks are left out, embedded fonts in them are not carried over, and their notes pages use the first deck’s notes master. Section names and custom shows of the later decks are not carried over. The merged file has several slide masters, which PowerPoint supports but can make the Design tab list several themes. Use the first deck’s design is offered only when every layout name matches and every placeholder has a place on it. Merge as pictures cannot be edited and drops notes, links and animation.
Privacy
Every deck is read and the merged file is built inside your browser tab, so none of the presentations is uploaded. A request that counts the use goes to this site when you download and carries no part of your file.
