PDF Compressor: Reduce PDF

Compress PDF files quickly, reduce file size, and keep your documents private with PDF Compressor: Reduce PDF.

Need to make a PDF smaller for email, work, school, online forms, or document uploads? PDF Compressor helps you reduce PDF file size directly on your iPhone or iPad — with no account required and no document uploads to our servers.

SMART PDF COMPRESSION

Reduce PDF size while preserving text, links, and document structure whenever possible. Smart Compression is ideal for documents where readability and selectable text matter.

MULTIPLE COMPRESSION OPTIONS

Choose the compression method that fits your needs:

• Smart Compression — Reduce file size while preserving text and links
• Maximum Compression — Get a smaller file using stronger compression
• Target Size — Try to compress your PDF toward 500 KB, 1 MB, 2 MB, 5 MB, or a custom size
• Multiple quality options for stronger compression

BUILT FOR REAL-WORLD FILE SIZE LIMITS

Trying to upload a PDF but the file is too large? Choose a target size and let PDF Compressor reduce the document as much as possible while protecting its structure.

Some PDFs are already highly optimized, so the exact target size cannot always be reached. The app clearly tells you when further compression would reduce document quality or make the file larger.
