Features

Smart Compression

Reduce file size by up to 80% while maintaining visual quality using intelligent image and media optimization.

Batch Processing

Compress multiple PPTX files at once. Perfect for teams sharing large presentation libraries.

Lossless Mode

Choose between maximum compression or lossless mode that preserves every pixel.

Compress PowerPoint files by up to 80% without visible quality loss — perfect for email attachments, faster uploads to Drive or SharePoint, and reducing storage costs. Our smart compression engine analyzes every image, video, and embedded media file in your PPTX, applies optimal compression settings (re-encoding images, downscaling oversized graphics, and removing hidden metadata), and rebuilds a fully functional .pptx file. Animations, fonts, transitions, speaker notes, and slide layouts are all preserved exactly as you designed them. Ideal for shrinking that 200 MB sales deck down to under 25 MB so it actually sends through your company's email gateway, or compressing a media-heavy keynote so it loads instantly on stage. No software install — works in any browser, on any operating system.

Frequently Asked Questions

How much can it actually reduce file size?

Typically 50–80% reduction depending on image content. A 200 MB image-heavy presentation often compresses to 30–50 MB, and lighter decks see 30–50% reduction.

Will my animations, transitions, and speaker notes survive?

Yes. The compressor only optimizes images and media. Animations, transitions, slide layouts, fonts, charts, and speaker notes are preserved exactly as they were.

Will image quality visibly degrade?

Almost never — we use perceptual compression that targets the threshold below which the human eye can't detect differences. For ultra-high-fidelity needs (print at 300 DPI), use the 'high quality' setting.

What's the maximum file size you support?

Up to 500 MB per upload — covers virtually all real-world PowerPoint files.

Can I choose how aggressive the compression is?

Yes — three presets: 'maximum compression' (smallest file), 'balanced' (recommended), and 'high quality' (least compression, best for print).

Are my files secure?

Yes. Files are encrypted in transit, processed in isolated containers, and automatically deleted within 1 hour of compression.

Does it work on .ppt (older format) too?

Yes — both .pptx (PowerPoint 2007+) and .ppt (older) formats are supported. Output is always modern .pptx for best compatibility.

Will compressed files still open in Keynote and Google Slides?

Yes — compressed files remain fully compatible with PowerPoint, Keynote, Google Slides, LibreOffice, and any other PPTX-compatible software.
