Compress PowerPoint (PPTX) File API

What it does

PowerPoint Compressor reduces the size of a .pptx presentation while keeping it editable. Send a presentation file and, optionally, set maxDpi to cap image resolution or set removeNotes to strip speaker notes before compression.

Use it when you need to make slide decks easier to email, upload, or store without changing them into another format. It accepts presentations up to 50 MB and 500 slides, and it only works with .pptx files that are not password-protected.

The response is the compressed PowerPoint file as binary output, so you can pass it straight into your storage, download, or delivery flow. That makes it useful for document pipelines, internal tooling, and apps that need to reduce deck size before sharing.

If you already handle presentation uploads, PowerPoint Compressor gives you a simple way to trim file size before the file reaches users, reviewers, or downstream systems.
