Compress PDF – Optimize Your Documents Instantly
Sending large PDF files can be a nightmare. Whether it's an email bouncing back or a portal rejecting your upload, file size limits are a constant hurdle. High-resolution images and complex formatting make PDFs look great, but they also make them heavy.
Our Compress PDF tool is the solution. It intelligently analyzes your document to reduce its footprint without compromising readability. Share your work faster and easier than ever before.
Understanding PDF Bloat
Why is your file so huge? It's usually a mix of unoptimized assets.
Image Resampling
We downscale images to a standard 144 DPI or 72 DPI, which is perfect for screens, significantly cutting down file size.
Secure Processing
Your privacy is paramount. All compression happens locally in your browser; no files are ever sent to a remote server.
Font Subsetting
We remove unused characters from embedded fonts, stripping away invisible weight from your document.
Faster Loading
Compressed files load quicker on websites and mobile devices, improving the experience for your readers.
Frequently Asked Questions (FAQs)
How does PDF compression work?
It works by removing redundant data, optimizing images, and simplifying the internal structure of the file. Think of it as packing a suitcase more efficiently—same contents, less space.
Is there a file size limit for uploads?
Since the processing is done on your device, the limit depends more on your computer's memory (RAM) than our tool. Generally, files up to 100MB are handled smoothly.
Can I compress scanned documents?
Yes! Scanned PDFs are often just large collections of images. Our tool is particularly effective at shrinking these types of files by optimizing the scanned images.
Will my links and bookmarks be preserved?
Absolutely. The compression process targets visual elements and metadata. The functional structure of your PDF, including hyperlinks, bookmarks, and form fields, remains intact.
Is this tool free to use?
Yes, it is completely free. You can compress as many files as you need without any hidden costs or watermarks.
