Compress PDF PDF Tools
Got a PDF that is too big to email? Or maybe your file is eating up storage space and you need to slim it down without losing quality? You are in the right place.
With AFFLIGO, you can shrink your PDF file size in under a minute. No software to install, no account to create, and your files never leave your browser. Just upload, compress, and download a smaller, optimized PDF that looks just as good as the original.
We built this because we have been there ourselves. That moment when you try to attach a PDF to an email and get the dreaded "file too large" error. Or when your cloud storage is full and you need to free up space fast. Our tool handles it in seconds, and your documents stay private the entire time.
Quick tip from our team: Image-heavy PDFs shrink the most — often by 50-80%. If your PDF is mostly text, the reduction will be smaller but still noticeable. Try different compression levels to find the sweet spot between size and quality. Check out our batch compression guide for handling multiple files at once.
Why Professionals Choose AFFLIGO for PDF Compression
There are plenty of PDF compressors out there. Some are slow. Some reduce quality so much your document looks like a blurry photocopy. Others force you to upload your files to their servers, which is the last thing you want for sensitive documents.
We built ours differently. Here is what makes it stand out.
Your Files Stay on Your Device
All compression happens inside your browser. Your PDF is never uploaded to a server, never stored in a cloud, and never seen by anyone but you. For contracts, financial reports, medical records, or any confidential document, that level of privacy is essential. We do not even have access to your files.
Smart Compression, Not Brute Force
Some tools simply crush your PDF to a smaller size and call it done. The result? Blurry images, broken fonts, and text that is hard to read. Our smart compression algorithm analyzes your document and applies the right level of optimization for each element. Images get optimized without turning into pixel soup. Text stays crisp and fully searchable. The layout remains intact.
Three Compression Levels to Choose From
Not every PDF needs the same treatment. That is why we offer three modes:
- Light compression – Minimal size reduction, maximum quality preservation. Best for documents where every detail matters.
- Balanced compression – A solid middle ground. Good size reduction with quality that is still excellent for most purposes.
- Strong compression – Maximum file size reduction. Perfect for email attachments and web uploads where size is the priority.
Batch Process Multiple Files
Got a folder full of PDFs that all need shrinking? Our batch compression lets you upload multiple files at once, apply the same compression level to all of them, and download everything in one shot. Same settings, consistent results, zero repetition.
Works on Any Device
Desktop, laptop, tablet, phone — it does not matter. As long as you have a modern browser, you can compress PDFs anywhere. No app store, no installation, no updates to worry about.
Once your PDFs are compressed, you might also want to merge multiple files into one document, split out specific pages you need separately, or protect your PDF with a password for extra security — all with the same privacy-first, browser-based approach.
