Reading document layers...
We've all been there — trying to email an important PDF or upload a document to a job portal, only to get an error saying the file is too big. This tool resizes bulky documents instantly without turning your text or images into a blurry mess, and your file never travels to an unknown server — everything runs safely inside your own browser.
Your document's text and images stay clear and readable at every compression level.
Choose Low, Medium, or High depending on how small you need the file to be.
Compression happens in seconds, right in your browser tab.
Android, iPhone, tablet, or laptop — no app or plugin required.
Add your PDF: Drop your file into the upload box above or click "Browse PDF File" to pick it from your device.
