Privacy Policy

1. Core Principle: Full Local Processing Priority

All compression operations for images, GIFs and PDF files on this site are completed locally in the user’s browser by default. During the whole compression process, original files and processed files will never be uploaded to cloud servers, nor will any user files be stored on the server.

Local operation is the fixed default mode for image compression. When compressing images in JPG, PNG, WebP and other formats, all calculations are finished in the user’s browser without uploading original images to the server for transit processing.

2. No Automatic Server Upload & Storage

The default file processing process of the platform has no automatic upload channel. The server will not actively receive or store any files uploaded by users for compression.

The file compression function runs independently and is not connected to any cloud file storage system. External data transmission only occurs when users actively submit files to third-party platforms. The compression function itself will not secretly enable any file upload access.

3. User Privacy Rights Statement

Users’ original files will never be automatically uploaded or leaked during compression.

Custom compression settings and personal preferences are only temporarily saved in the current browser session, and will only be stored permanently after users authorize browser local cache.

In-site advertisements, data statistics and other third-party services are completely isolated from local file processing. Users can choose to turn off or manage related services freely.

4. Scope of Privacy Statement

This privacy statement only clarifies the default operating rules of the core compression function. It does not cover security risks caused by browser permissions, third-party ad scripts, data analysis tools and external jump links. Users can evaluate overall privacy security according to their own usage environment.

5. Practical Significance of Local Processing

Office screenshots, working materials, private pictures and unreleased documents used daily all involve personal and workplace privacy. FastAiZip clearly defines file processing boundaries, eliminates hidden dangers of unauthorized file uploading and leakage from the source, and fully protects users’ file privacy and data security.
