PowerPoint Template & Theme — Apply a Uniform Look to Every Slide
Give your entire deck — .pptx, legacy .ppt, or OpenDocument .odp — a cohesive template in one click: a consistent font everywhere, a harmonious accent palette, and a uniform slide background. Everything runs locally in your browser — your file never leaves your device.
Why use Template & Theme
One-click style presets
Pick from curated looks — Clean, Modern, Dark, Sunset, Forest, or Mono — and every slide is restyled instantly.
Global font replacement
The chosen typeface replaces the deck's theme fonts and every text run, so titles, body text, and notes all match.
Accent-driven color scheme
One accent color derives a full harmonious palette — dark and light pairs plus six accent tones — for charts, tables, and highlights.
Uniform backgrounds
Every slide, master, and layout gets the same solid background, replacing image or gradient fills.
100% private & local
Theming happens entirely in your browser. Nothing is uploaded, so confidential decks stay on your machine.
Batch multiple decks
Drop several .pptx, .ppt, or .odp files and apply the same template to all of them, then download each result or a combined ZIP.
What Template & Theme does
The Template & Theme tool gives every slide of a PowerPoint presentation one consistent identity. It rewrites the deck's theme file — the part PowerPoint uses to resolve fonts and colors — so the chosen font and an accent-derived palette apply everywhere that references the theme. It also replaces the font on every slide and rewrites or inserts a uniform solid background on each slide, master, and layout. The result is a rebranded deck in seconds: consistent typography, a coherent color story, and a clean background, ready to present or share.
How to apply a template to a PowerPoint
Three quick steps — no account, no upload, no Office install.
Add your presentations
Click or drop one or more .pptx, .ppt, or .odp files. Each file is processed completely in your browser.
Pick a style
Choose a preset — Clean, Modern, Dark, Sunset, Forest, or Mono — or select Custom to set your own font, accent color, and background.
Apply and download
Click Apply. Each deck is rethemed in place and you can download the styled presentation individually or all at once as a ZIP.
Notes
Template & Theme keeps your original format: .pptx and .odp decks are themed natively in your browser, while legacy binary .ppt files are converted to .odp, themed, and converted back to .ppt using the in-browser LibreOffice engine. The tool rewrites theme fonts, colors, and backgrounds, but intentionally leaves your slide layouts, pictures, charts, and notes untouched. If a slide was authored with an explicit local color or font override, that slide may keep its original look; re-apply from a clean copy when that matters.
