Getting a 24 MB pitch deck under your email limit (without ugly artifacts)

Gmail's attachment comfort zone is roughly 25 MB, but plenty of corporate Exchange setups cap lower. I watched a founder lose an hour because a pitch deck with embedded screenshots clocked in at 24.7 MB — bounced twice.

What makes PDFs fat

• Uncompressed images inside slides exported from Keynote or PowerPoint
• Embedded fonts duplicated per page
• High-resolution scans pasted as full-page bitmaps
• Multiple copies of the same logo asset (happens more than you'd think)

Compression does not have to mean 'unreadable.' Modern PDF recompression re-encodes images and strips redundant objects. Text stays sharp because it's vector or properly embedded glyphs.

My two-pass habit

First pass: aggressive enough to get under the limit. Second pass: only if visuals look soft on a laptop screen. If chart labels blur, I re-export the source deck with smaller image export settings instead of crushing the PDF again.

Running compression locally means you can iterate three sizes in a minute without waiting on a server queue. Try Toolncy's compress PDF, compare file size and a zoomed-in chart, then send.
