About This Tool
PDFs quietly grow over time - embedded fonts, high-resolution images, and redundant data add up, until a simple manual becomes 50MB. This tool shrinks PDF file size by stripping that weight while keeping text sharp and layouts intact, entirely in your browser. Give any bulky PDF a diet and download a version that is a fraction of the original.
How It Works
Three simple steps to get your optimized PDF.
Upload Your PDF
Drag and drop or browse to select your PDF file. Files are processed locally and never leave your device.
Choose Compression Level
Pick Low, Medium, or High compression. Higher levels produce smaller files while keeping text and layout readable.
Download the Result
Save your compressed PDF. It is ready to upload, email, or share — no accounts, no fees.

Frequently Asked Questions
What makes PDF files so large in the first place?
Embedded images are usually the culprit - a single high-resolution scan or photo can account for most of a PDF's size. Fonts and redundant data add the rest.
How small can a PDF get?
Most PDFs shrink by 50-90% depending on content. Image-heavy documents compress the most; simple text files are already lean and drop less.
Is there any reason to keep the original file?
If you might need the exact original for archival, keep a copy. For daily use - email, uploads, sharing - the compressed version is all you need.
