PPTX vs SVG: Format Comparison

Key differences between the two formats

Feature	PPTX	SVG
Type	Presentation	Vector image (XML)
Scalability	Fixed slide size	Infinite (any resolution)
Text	Embedded fonts	Editable SVG text
File size	1-50 MB	50 KB - 2 MB
Web display	Requires viewer	Native in browsers
Editing	PowerPoint	Vector editors (Illustrator, Inkscape)
Animation	Transitions, animations	CSS/JS animations possible

When to Convert

Common scenarios where this conversion is useful

Embedding scalable diagrams in web pages

SVG slides render crisply at any screen resolution. Embed converted slides in web pages where they scale from mobile to 4K without pixelation.

Editing slide graphics in vector editors

Need to modify a diagram from a PPTX? Converting to SVG lets you open it in Illustrator or Inkscape and edit individual shapes, colors, and text.

Creating responsive presentation previews

SVG slides in a responsive web layout scale naturally to any viewport width. No need for multiple resolution versions like you'd need with raster images.

Preserving editability for design teams

Designers can take PPTX slides and convert to SVG to get editable vector elements without needing PowerPoint. The SVG can be imported into Figma, Sketch, or other design tools.

Frequently Asked Questions

Does this preserve vector shapes?

Yes. LibreOffice exports shapes, lines, and text as SVG vector elements. These remain editable in vector editors and scale infinitely without quality loss.

What happens to embedded images?

Raster images (photos, screenshots) embedded in the slide are converted to base64-encoded images within the SVG. They don't become vector — only native shapes and text are preserved as true SVG elements.

Can I edit the SVG in Figma or Illustrator?

Yes. The SVG output opens in any vector editor. You can modify shapes, change colors, edit text, and restructure elements freely.

Is the SVG output clean?

LibreOffice produces functional SVG that renders correctly. Complex slides may generate verbose SVG code. You can optimize the output with SVGO or Inkscape's SVG cleaner.

Does this convert all slides?

The converter processes the first slide. To convert multiple slides, you'd need to convert each separately.

Are animations preserved?

No. SVG captures the static state of the slide. However, you can add CSS or JavaScript animations to the SVG elements after conversion.

How does SVG compare to PNG for slides?

SVG is better for diagrams, charts, and text-heavy slides because it scales infinitely. PNG is better for slides with photos or complex visual effects.

Is this secure?

Files are uploaded via encrypted TLS, processed using LibreOffice, and auto-deleted immediately. We never store or examine your presentations.

What's the maximum file size?

25MB for the free tier (500MB on Pro). The authenticated API supports up to 500MB.

Can I use SVG in PowerPoint?

PowerPoint 2019+ and Office 365 support inserting SVG images. Older versions may not. The converted SVG works as an image in any modern Office application.
