Supports .ppt and .pptx formats · Maximum: 800MB
Maximum compression rate of 90%, fully preserving all animations, transitions, and sound effects, maintaining absolute HD quality, perfect display on 4K, 2K, and 1080p monitors.
We perform intelligent compression processing on image resources in PPT / PPTX presentations, including JPEG, PNG, GIF, WebP, SVG, BMP, TIFF, EMF, WMF, and 3D models. Through dithering algorithms and pixel-level optimization, we effectively reduce PPT file size while maintaining image clarity and visual quality.
We re-encode video and audio files embedded in PPT / PPTX, through frame-by-frame and segment-by-segment optimization of media content, achieving virtually imperceptible visual and auditory changes, significantly reducing PPT file size, making presentations both lightweight and clear.
In PPT / PPTX presentations, embedded font files typically occupy 10–25MB of storage space, which is one of the common causes of excessively large PPT file sizes. You can use WPS Office or Microsoft PowerPoint to set fonts to embed only used characters (embedded fonts cannot be edited), or choose not to embed any fonts, thereby effectively reducing PPT file size.
💡 Additionally, you can also use Premium or higher compression mode on this page to automatically remove embedded fonts from PPT. After removing fonts, page layout may require slight adjustments, but it can usually significantly reduce PPT file size.
To achieve the best PPT compression results, we perform complete processing on all resource items in the presentation, so processing time may be slightly longer. Please be patient.
🎯 Premium User Exclusive: During processing, we will generate a task record for you, and you can check the progress at any time. You will receive email notification when processing is complete, and the entire process usually takes no more than 20 minutes, so you don't need to wait throughout.
💡 If your PPT file has already been compressed multiple times, its optimization space may be very limited, and the compression effect will be relatively weak. To achieve the best PPT compression results, we recommend uploading original, uncompressed PPT files, to fully leverage the advantages of our intelligent compression algorithms.
