Compress PDF Online: Reduce File Size Free

Most "free" online compressors have a hidden cost: your privacy. They require you to upload your file, process it on their cloud, and then download it.

• Our Approach: We use advanced WebAssembly to run the compression logic on your device.
• No Uploads: Your file never leaves your computer.
• No Limits: Compress as many files as you want, as often as you want.
• Instant Results: Since there's no upload/download time, it's often faster than cloud tools.

1. Open the Tool: Navigate to our Compress PDF Tool.
2. Select File: Drag and drop your large PDF file.
3. Choose Level: Select your desired compression level (Low, Medium, High).
4. Compress: Watch as the tool shrinks your file locally.
5. Save: Download your optimized PDF immediately.

Note: For maximum compression, choose "High", but "Medium" usually offers the best balance between size and quality.

Security is our top priority. When you use our online PDF compressor:

• Zero Data Transfer: Your document contents are never sent over the internet.
• No Copies: We don't keep a copy of your file because we never receive it.
• gdpr Compliant: Perfect for legal contracts, medical records, and financial statements that require strict privacy.

Not if done correctly. Our tool intelligently removes redundant metadata and optimizes images. You likely won't notice a difference in visual quality on screen, but the file size will be significantly smaller. This makes it perfect for email attachments and web uploads.
