Quick answer
Compress PDF: Lighten your PDF
Compress PDF targets a smaller file for email, mobile download, web publishing, portals, or storage while retaining acceptable readability. The correct compression level depends on whether the PDF contains office text, photographs, diagrams, fine print, scans, or material that may later be printed.
Reviewed by the PlusConvert Editorial Team · Updated August 24, 2026When this tool is useful
- Reducing an attachment to fit an email or application portal limit
- Publishing downloadable manuals or catalogs that load well on mobile connections
- Creating lightweight review copies while preserving a higher-quality archive master
Professional quality
- Inspect small text, charts, signatures, QR codes, barcodes, and photographs at 100 percent zoom.
- Compare file size against actual visual loss instead of choosing maximum compression automatically.
- Keep an untouched master because repeated compression can create permanent artifacts.
International and regional use
Document conventions vary by country and language. Check page size, reading direction, dates, numbers, fonts, accessibility, privacy, and retention rules. PlusConvert is a global online service and does not claim a physical local office or map listing.
E-commerce and business
Keep product names, identifiers, prices, currencies, and policy links consistent across PDF catalogs, product pages, feeds, invoices, and orders. The transactional page should remain the source of truth for stock and checkout.
What Compress PDF does not solve
Compression cannot make every PDF dramatically smaller. Text-based PDFs may already be efficient, while scan-heavy files offer more opportunity but greater quality risk. Compression also does not repair corruption, remove confidential metadata, or guarantee compliance with a portal’s exact requirements.
Method and trust
Each PlusConvert page explains its purpose, accepted formats, workflow, limits, and safety checks. We publish no invented ratings or guarantees. High-risk legal, medical, financial, or accessibility documents require qualified review.
FAQ
Questions about this PDF tool
Why is my compressed PDF still large?
Embedded high-resolution images, many pages, fonts, attachments, or an already optimized source can limit further reduction.
Does PDF compression affect printing?
Aggressive image downsampling can soften photographs, diagrams, and fine text. Use a print-oriented setting when physical output matters.
Should I compress before or after editing?
Finish editing, merging, OCR, and page organization first, then create the final compressed delivery copy.
