Sending PDF documents via email often results in annoying "file exceeds 25MB attachment limit" errors. High-resolution scanned documents, embedded fonts, and uncompressed artwork quickly blow up file sizes.
How PDF Compression Works: Instead of degrading letter text, intelligent PDF compression analyzes internal streams. It strips redundant XML metadata, optimizes font tables, and uses stream object deduplication.
With ToolBox AI PDF Compressor, all processing happens directly in your browser. There is zero risk of confidential contracts or bank statements leaking to unmonitored external servers.
Tips for Best Results: If your PDF contains numerous high-resolution photos, consider using our Image Compressor first, then stitching them together with our Image to PDF converter.
No account, no fees, and zero watermarks.
