Reducing PDF size for email, government portals, job applications and document sharing.
Targeting an approximate KB size when the original PDF contains large scanned pages.
Use Compress PDF when a PDF is too large for email, online forms, storage limits or document sharing. Compress PDF online free and reduce PDF size to a target KB in your browser. No upload and no account required. This gives the page a practical role beyond a simple upload area: it helps you decide whether this is the right tool before selecting a private file.
Before you begin, confirm the target KB or MB size, whether the PDF is scanned or text-based and how much clarity must be preserved. For Compress PDF, the most important controls usually relate to Low, balanced and high quality modes, Optional target KB size and Custom DPI and image quality. Knowing those details first reduces repeated exports and helps avoid quality loss or rejected uploads.
A reliable workflow is to start with balanced compression, use target size only when needed, and review the output before using stronger settings. Because the processing happens in the browser, the original PDF file remains available on your device while the tool creates a separate output for download.
After export, check small text, signatures, seals, QR codes, stamps and page images after compression. This final review is important for application forms, business documents, public uploads and any file that will be forwarded to someone else.
Settings: Use balanced compression and a realistic target size.
Review: Zoom into signatures, stamps and small text.
Settings: Try light compression first instead of forcing a tiny target.
Review: Check whether selectable text still behaves as expected.
Yes. Enter the target KB value and the tool will try to create a smaller PDF near that limit.
Strong PDF compression may rasterize pages, which can turn text into page images.
Scanned and image-heavy PDFs usually compress more than text-only PDFs.
