How to compress pitch decks for email

Investors open dozens of decks a week. A direct attachment opens instantly inside the mail client and signals that you have your operational details together. A cloud link adds a redirect, a sign-in friction, and a permissions check - three places to lose attention before the first slide loads.

Compressing the deck under 8MB lets you attach it directly to the same email that introduces you.

Use this workflow for fundraising decks, sales decks, partner pitches, and board updates.

1. 1Export the latest version from Figma, Keynote, or PowerPoint as a .pptx.
2. 2Open the Docsora pitch deck compressor.
3. 3Drop the deck into the upload area.
4. 4Choose Balanced (50% compression) - or Maximum (80% reduction) if you need to clear a 10MB enterprise cap. Preserve Quality (30% reduction) is available for decks that will be printed.
5. 5Download the optimized deck and attach to the email directly.

Typography stays exact when fonts are embedded in the original PPTX. Animations, transitions, and builds are preserved frame for frame. Embedded video continues to play inside PowerPoint and Keynote - the codec is updated to a modern web format but the playback experience is unchanged.

Speaker notes and slide ordering are untouched. The deck the investor opens is the deck you sent.

Send PPTX when you want the recipient to experience the deck as designed - with animations, builds, and live video. Send PDF when you want a static, locked-down version that prints predictably and cannot be edited.

If you do send PDF, compress that PDF as a separate step. PowerPoint's built-in PDF export produces files that are 3–4x larger than necessary.

Delete legacy slides hidden at the end of the file before compressing. Hidden slides still occupy bytes and sometimes ship sensitive earlier versions you did not intend to share.

Replace screenshots of UI with crops at their final display size - full-resolution Retina captures of your product are the single most common source of deck bloat.
