What it does

Text Vectorization
Fixes font problems

Text is converted to vector graphics, so there's nothing to install. Slides look the same on any computer or device.

Graphics Preservation
Everything else stays

Images, charts, SmartArt, tables, and layouts are untouched. Only the text becomes non-editable.

Watermarking
Optional watermark

Add a semi-transparent watermark to mark slides as confidential or for internal use only.

FAQ

Files are deleted immediately after conversion and are never viewed by anyone on our end. The entire process is automated.

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

It should look identical — same layout, colors, graphics, and visual style. The only change is that text can no longer be 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.
