PPT压缩

• Outcome: Pass

  1.0.0

Overview

This is a local PPTX compression tool whose file changes match its stated purpose, but users should keep originals because compression can reduce quality or remove some presentation data.

Install only if you want a local tool that rewrites PPTX media to reduce file size. Keep a backup of important presentations, use lower compression for quality-sensitive decks, and disable video or PNG conversion when preserving originals matters. Use a trusted ffmpeg installation if enabling video compression.

Missing User Warnings

Medium

• Confidence: 82% confidence
• Finding: This skill performs lossy image/video recompression and removal of thumbnails, comments, and metadata, but the description does not clearly warn users that output quality may be permanently reduced and embedded content may be stripped. In a document-processing context, that can cause irreversible data loss, privacy-impacting metadata removal, or unintended destruction of review artifacts such as comments.
