Convert PowerPoint to portrait
Drop a landscape deck and get it back as a tall 9:16 portrait deck, for phones, vertical screens and handouts. Every slide, layout and master resized in one go. Free.
Three steps, done
Upload the deck
Drop a .pptx. The current slide size is read and shown, e.g. 16:9 · 13.33 × 7.5 in.
Choose how to scale
Scale to fit keeps every element on the slide, centred. Scale to fill and Stretch are there for decks whose content already sits in a narrow column.
Download the portrait deck
Press Convert and the portrait .pptx downloads at 7.5 × 13.33 in, ready to rearrange in PowerPoint.

Before
Landscape slides
Fine on a projector, awkward on a phone, a vertical display or a printed A4-style page.
After
A 9:16 portrait deck with everything on it
Slides, layouts and masters at 7.5 × 13.33 in, the original content scaled and centred, ready to rearrange for the tall format.
Vertical deck, spoken
Portrait decks usually end up on phones and screens with nobody presenting. Tell Noty in the Studio chat and every slide gets a voiceover, timed to move on by itself.
What happens to your slides
Portrait turns the slide on its side: 7.5 inches wide, 13.33 tall. The tool changes the slide size, then moves and resizes every shape to match, in one of three ways.
Scale to fit
Every shape, picture and text box moves and resizes by the same factor, the one that keeps the whole slide visible, and the content is centred. Nothing is distorted or cut off; the new edges show the slide background.
Scale to fill
Everything grows by the factor that covers the whole new slide, then is centred. No empty edges, but content near the edges can end up partly off the slide.
Stretch
Positions and sizes are stretched across and down separately, so the layout fills the new slide exactly. Pictures, circles and icons change proportion, which is why it isn’t the default.
Why font sizes stay the same
Text boxes are resized, but the point size of the text is left alone. Scaling fonts by 0.75 would turn 18 pt body text into 13.5 pt, and it’s easier to enlarge a few titles by hand than to fix every text box that got too small. If a box is now too narrow, the text wraps onto another line.
Layouts and masters too
The slide masters and layouts are resized along with the slides, so new slides you add afterwards come out in the new shape with their placeholders in the right place.
Tables, groups and charts
Grouped shapes scale as a unit, table columns and rows scale with the table, and charts are resized as objects; their contents redraw at the new size.
Going portrait, three ways
PowerPoint can switch a deck to portrait in its Slide Size dialog, when you have PowerPoint to hand. Either way, a landscape layout needs rearranging to use the tall slide well.

What to expect when a landscape deck goes portrait
A 16:9 slide is wide and short; a 9:16 slide is narrow and tall. No scaling can make a layout designed for one fill the other without either shrinking it, cropping it or distorting it, so the converted deck is a starting point to rearrange, not a finished design.
Scale to fit is the safe choice. The whole original slide shrinks to match the narrow width (a 16:9 slide to just over half its size) and sits in the middle of the tall slide, with background above and below. Everything is still there. Text keeps its point size, so text boxes that got narrower wrap onto more lines.
From there, the quickest route is to move the picture or chart into the top half, stack the text below it, and enlarge titles. Because the layouts and masters were converted too, new slides you add already have portrait placeholders.
Scale to fill and Stretch make sense only for decks that already keep their content in a narrow central column. On a typical landscape slide, fill pushes the sides far off the slide and stretch makes every picture tall and thin.
Portrait, and now narrated
Noty writes the narration from your slides, voices every one of them in a natural voice or yours, and hands back a PowerPoint that plays itself.

Frequently Asked Questions
How do I make a PowerPoint portrait?
Drop the deck above and press Convert. The slide size becomes 7.5 × 13.33 inches (9:16 portrait), and every slide, layout and master is resized to match, with the content scaled to fit and centred.
What size is the portrait slide?
7.5 × 13.33 inches (19.05 × 33.867 cm): PowerPoint’s widescreen slide turned on its side, the 9:16 shape of a phone screen.
Why does my content only fill the middle of the slide?
A landscape slide scaled to fit a portrait width comes out as a band across the middle. Nothing is lost; rearrange the content in PowerPoint to use the height, or try Scale to fill if your slides keep their content in a narrow column.
Does it change font sizes?
No. Shapes, pictures and text boxes are moved and resized, but text keeps its point size. If a text box got narrower, its text wraps onto more lines; adjust the few that need it in PowerPoint.
Will my images be distorted?
Not with Scale to fit or Scale to fill: both scale width and height by the same amount. Only Stretch changes proportions, and only if you choose it.
Is my deck uploaded?
No. The file is processed in your browser and never leaves your computer.
Can Notevibes narrate the deck too?
Yes. Tell Noty in the Notevibes Studio and it writes narration for every slide from the slide text or speaker notes, voices it in a natural AI voice or your own cloned voice, and hands back a narrated .pptx that auto-advances, plus the MP3.
