Send a pitch deck without the oversized attachment.
A pitch deck full of screenshots, product photos and logos can grow into a heavy .pptx file. Timamu compresses a .pptx or .ppsx in your browser and saves a separate, lighter copy, so the deck goes out while the original stays untouched.
Timamu compresses a pitch deck in your browser so the PowerPoint file is easier to email. Choose the .pptx or .ppsx, compress it and download the lighter copy; the original deck stays untouched. Embedded videos are kept as they are. Free compresses a presentation up to 100 MB.
Free compresses a .pptx or .ppsx presentation up to 100 MB. Premium compresses one up to 2 GB. Choosing a target size is Free for a single PowerPoint file.
This guide covers one job: getting a pitch deck small enough to attach to an email for an investor, from the finished .pptx to the file that goes out.
Why pitch decks grow heavy
A slide holds whatever was pasted into it. A screenshot of the product, a team photo or a customer logo stays at the size it had when it was added, and a deck of thirty slides can carry dozens of them. Embedded video adds more on top.
Timamu compresses the presentation file and keeps embedded videos as they are, so a deck with video can stay large. The original file is never replaced.
Worked example: a founder's deck for an investor email
A founder has a final deck with product screenshots and team photos. The email service refuses the attachment because of its size limit. Gmail's attachment limit is about 25 MB.
- Save the final deck as .pptx and put the version or the date in the file name.
- Open the PowerPoint tool on Timamu Web and choose the file.
- Choose a target size when the recipient or the email service has a limit. For a single PowerPoint file this is Free.
- Start the job and wait for the result.
- Download the lighter copy.
- Open the new copy in the presentation app and move through every slide before sending it.
What to check before sending
- Read the charts and any small text at presentation size.
- Look at logos and product screenshots for soft edges.
- Play the animations and transitions that matter for the pitch.
- Play any embedded video from start to finish.
- Confirm the slide count and the order match the original.
- Keep the original .pptx as the master copy for later edits.
What to expect
The result is a smaller file, not a promised size. A deck of text and simple shapes has little to shrink, so its result can be close to the original, while a deck full of large images has the most room. When Timamu cannot produce a smaller file, the original is kept and the result says so. Embedded videos stay as they are, so a deck with video may remain large.

Questions
Can Timamu compress a pitch deck for email?
Yes. Timamu compresses a .pptx or .ppsx presentation so it is easier to send as an attachment. Gmail's attachment limit is about 25 MB, and other email services set their own limits.
Does compression change the slides?
Compression changes the images inside the file, so every slide deserves a look before sending. Keep the original presentation as the master and send the compressed copy.
Are embedded videos removed?
No. Embedded videos are kept as they are during PowerPoint compression.
Which presentation formats work?
Timamu supports .pptx and .ppsx. A deck from another presentation app is exported as .pptx first.
Is the pitch deck uploaded to Timamu?
No. Supported jobs are processed on your device, in your browser, and the presentation is not uploaded to a Timamu processing server. Timamu needs internet to load.
