How do I compress a PowerPoint file for WhatsApp?

Use DeckMedic Smart Shrink. It recompresses every image inside the PPTX using OffscreenCanvas, targeting 80% JPEG quality and a maximum dimension of 1280px. It also strips embedded thumbnails and preview images. Most decks reduce by 60-85% in file size. The resulting PPTX opens identically in PowerPoint and meets WhatsApp's 100 MB file size limit.

How do I extract speaker notes from PowerPoint as a text file?

Use DeckMedic Teleprompter Export. It reads every ppt/notesSlides/notesSlideN.xml file, strips XML tags, and outputs a clean text file formatted as: SLIDE 1 / [title] / [notes text] / --- / SLIDE 2 / etc. The output is suitable for teleprompter apps, printed speaker sheets, or reading from a phone during a presentation.

How do I post PowerPoint slides to LinkedIn as a carousel?

LinkedIn carousels require 1:1 square images (1080x1080 pixels). DeckMedic LinkedIn Carousel reformats each slide to a 1080x1080 canvas using OffscreenCanvas, exports each slide as a PNG, and packages all images in a ZIP. Upload each image as a multi-image LinkedIn post to create a native carousel.

What is the maximum PPTX size for WhatsApp?

WhatsApp allows file attachments up to 100 MB on most platforms. However, many corporate WhatsApp Business accounts and many mobile devices refuse files larger than 20-30 MB in practice. Smart Shrink targets a 10-20 MB output for typical 30-slide decks, ensuring reliable delivery across all WhatsApp platforms.

The Problem

✗ 30 MB deck bounces from email and exceeds WhatsApp limits — client cannot receive the file you spent days building
✗ Speaker notes are buried inside PowerPoint — no way to use them as a teleprompter script during a live conference or webinar
✗ 16:9 slides look wrong posted directly to LinkedIn — manual Canva resize takes 30 minutes per deck and still looks off

The Fix

✓ Smart Shrink recompresses every embedded image — deck drops to under 5 MB for email and mobile delivery, zero quality rework
✓ Teleprompter Export pulls all speaker notes into a clean scrollable text file — ready for any prompter app or screen reader
✓ LinkedIn Carousel Export reformats every slide to 1080×1080 square PDF — drop directly into a LinkedIn post with no redesign
