Introduction
The PDF Compress tool helps you quickly reduce the size of PDF files without significantly degrading visible quality. Whether you need to email large documents, upload them to platforms with strict size limits, or simply save storage space, this tool is designed for you. All processing happens locally in your browser, so your files never leave your device.
When to use this tool
Use this tool whenever you need to shrink the size of a PDF. Common scenarios include: sending large PDF presentations by email, uploading documents to systems with file size limits, saving disk space on your devices, or speeding up file transfer and downloads.
How to use
Upload your PDF file
Click the "Choose File" button or drag and drop a PDF onto the page. The tool supports most standard PDF files.
Select a compression level
Choose the compression level that best fits your needs: high-quality compression for printing, standard compression for everyday use, and high-ratio compression when you only need on-screen reading.
Start compressing
Click the "Compress" button and the tool will process your file directly in the browser. Processing time depends on the size and complexity of the PDF.
Download the compressed file
After compression finishes, you can preview the result and then download the compressed PDF file.
Examples
Compress a presentation for email
If you have a 30 MB PDF presentation that is too large to send by email, you can use this tool to reduce it to around 8–12 MB while keeping the slides clearly readable.
Optimize scanned documents
Scanned PDFs are often very large. With this tool you can significantly reduce their size while keeping text sharp enough to read comfortably.
