About PowerPoint compressor
This page is a PowerPoint compressor: it takes one presentation file and makes it smaller. Upload a PPT or PPTX file, choose a compression level, and the tool reduces its size so the file is smaller to store, upload and send. It runs in your web browser, with nothing to install.
Large presentations are awkward to email or upload to a portal, especially when they hold many slides and images. If a PowerPoint file is too big to send, you can reduce PowerPoint size to 500Kb, 200Kb or even 100Kb before sharing it. You can do this on a computer, phone or tablet whenever you need a smaller copy.
The tool removes data the document does not need, such as metadata and unused templates, and optimizes its images. You pick one of three compression levels, from Extreme for the smallest file to Low for higher quality. When it finishes, the page shows the new size, and you download the result.
