iAiDoc 灵识文档Compress PDF
All document processing happens locally on your device to protect your privacy.
How it works
Optimize supported PDF images and storage locally with clarity, balanced and smaller-file options. Retain text and vectors. Compression varies by file; keep the original if it cannot be reduced.
Keep your originals and check page order, boundaries and clarity after export.
Why do some PDFs barely shrink?
Savings depend on embedded images and storage. An already optimized file may not shrink. The original is kept if the result is larger; no fixed reduction is guaranteed.
Will text become an image?
Supported embedded images and storage are optimized while existing text and vectors are retained. Pages are not flattened into screenshots. Check small print and stamps after compression.
