About PDF Compressor
A bulky PDF can be a real headache when you need to email it, upload it to a portal with a size cap, or share it over a slow connection. Scanned documents and image-heavy reports often balloon to tens of megabytes for no good reason, and most people just want a smaller file that still looks fine.
This PDF Compressor shrinks your file by optimizing the images and data inside it, so the page count and layout stay exactly the same while the size drops. It runs in your browser for free with no signup and no watermark stamped on your pages. You pick the PDF, let it compress, and download a leaner version that opens normally in any reader.

FAQ
Will compressing lower the quality of my PDF?
The tool aims to keep text crisp and readable while reducing image weight. Heavily scanned files may show a slight drop in image sharpness, but everyday documents usually look the same.
How much smaller will my file get?
It depends on what is inside. Image-heavy and scanned PDFs often shrink a lot, while files that are mostly plain text have less room to compress.
Can I compress a password-protected PDF?
You should remove the password first using a dedicated tool, then run the unlocked file through the compressor.
Can I use PDF Compressor on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
