Compress PDF to Under 1MB
Compress large PDFs to under 1MB for web uploads, form submissions, and mobile sharing. Fast, free, and works entirely in your browser.
Many online portals — government applications, insurance claims, HR systems, academic submissions — impose a strict 1MB limit on PDF uploads. When your scanned documents, signed contracts, or image-heavy reports far exceed that limit, you need aggressive but intelligent compression that keeps the document readable.
Our compressor applies multi-level optimization to reach the 1MB target. It downsizes embedded images to screen-appropriate resolution (typically 150 DPI — more than sufficient for on-screen viewing), converts color spaces where possible, and strips redundant data structures. The result is a dramatically smaller PDF that maintains text clarity and enough image quality for any digital workflow.
For scanned documents, which are essentially large images embedded in a PDF wrapper, the size reduction can be particularly dramatic — from 20MB down to under 1MB. The text remains readable, signatures are recognizable, and form fields stay functional. This level of compression isn't suitable for print production, but for digital submissions and web uploads, it's exactly what you need.

Open Compress PDF ToolFrequently Asked Questions
Upload your PDF and apply compression. If the result is still over 1MB, increase the compression level. Our tool shows the output file size so you can iteratively compress until you hit the target.
Yes. Text remains sharp and fully searchable after compression. Images may show slight quality reduction at aggressive compression levels, but they remain clearly visible and readable for form submissions.
Yes, but the achievable quality depends on the number of pages and their content. A 5-page text document compresses easily; a 50-page image-heavy presentation may require extracting only the essential pages.
