Compress PDF Without Losing Quality
Shrink oversized PDFs in your browser when email limits or form uploads reject the original file. Choose a compression level to reduce PDF file size online free while keeping text readable—ideal when you need to compress PDF under 1MB or push toward smaller targets like 200KB or 100KB. Processing is client-side, so drafts and contracts never upload to a third-party server.
Size goal (best effort)
Compression level
Exact 100KB / 200KB / 1MB results depend on page count and images—use Strong for the smallest output, then step up if you need sharper pages.
How it works
Select your PDF
Choose the PDF file you want to shrink. Processing stays on your device — the file is not uploaded to a server.
Choose a compression level
Pick a quality level that balances file size and clarity for your use case (email, forms, or archival).
Compress the PDF
Run compression in your browser. TeenyPDF optimizes images and streams without sending your document online.
Download the smaller PDF
Save the compressed PDF to your device and use it wherever you need a smaller file.
Target sizes: 100KB, 200KB, and under 1MB
Use Strong compression when you need to compress PDF to 100KB or 200KB for strict portals; Recommended when you want to compress PDF under 1MB with clearer images; High quality when visuals matter more than bytes. Exact byte targets depend on page count and image density—try Strong first for the smallest output, then step up if you need sharper pages.
Frequently asked questions
Can I compress a PDF without losing quality?
Yes—start with the High quality or Recommended level to compress PDF without losing quality for most text documents. Stronger compression reduces images further when file size matters more than pixel sharpness.
How do I compress a PDF under 1MB?
Select Recommended or Strong, run compression, and check the before/after size. Multi-page image-heavy PDFs may need Strong to land under 1MB.
Can I compress a PDF to 100KB or 200KB?
Use Strong compression for the smallest files. Short text PDFs often reach ~100KB–200KB; long scanned decks may not, even at maximum compression, because each page still needs pixels.
Is compress PDF free and private?
Yes. TeenyPDF compresses in your browser at no cost. Files are not uploaded, so reduce PDF file size online free without giving a host a copy of your document.
Will compression make text unreadable?
Text-heavy PDFs usually stay clear at Recommended. If a page looks soft after Strong, re-run at High quality or Recommended for a larger but sharper file.
