What flattening a PowerPoint file does

Fixes missing-font problems

Every text box is converted to vector graphics, so there is nothing to install. No more PowerPoint font substitution — slides render identically on any computer, tablet, or phone.

Keeps images, charts & layout

Images, charts, SmartArt, tables, and slide layouts are untouched. Only the text is converted into non-editable graphics.

Optional confidential watermark

Add a semi-transparent watermark across every slide to mark your presentation as confidential or for internal use only.

The result: a flattened PowerPoint that looks identical to the original, with perfect fonts on every device — but all text is baked in as uneditable vector graphics. Ideal for merging presentations from different sources without font conflicts, and for secure distribution when you need to prevent text from being copied or edited while keeping the slides visually consistent.

No — that's the point. Text is converted to vector graphics, so it renders exactly as it did in the original, on any computer, with no fonts installed and no font substitution.

It should look identical — same layout, colors, images, charts, and visual style. The only change is that text can no longer be selected or edited.

Any modern PPTX file (PowerPoint 2007 or later). The output file works in all versions of PowerPoint that support PPTX.

That's one of the most common use cases. Since all text is baked into the graphics, you can combine decks from completely different sources with no font conflicts.

Usually 1–2 minutes, depending on how many slides are in the file.

No. Flattened text is vector graphics, not text, so it can't be selected, copied, or edited in PowerPoint — useful for protecting proprietary slide content before you share it.

Font embedding is unreliable: it often fails across platforms, and many licensed fonts don't allow embedding at all. Flattening removes the font dependency entirely, so the slides render correctly everywhere.
