Reduce PDF File Size Without Losing Quality

"File too large to send." — There are few notifications more annoying than this when you're trying to send an important email.

High-resolution scans and image-heavy presentations can balloon PDF file sizes to 50MB or more. Our PDF Compressor solves this by optimizing the file internals to reduce size by up to 80% while keeping it legible.

How Can We Reduce Size Without Ruining It?

It's a balance of math and perception. * Image Downsampling: We reduce the resolution of images to a standard web-viewable quality (usually 144dpi or 72dpi) which looks fine on screen but saves huge amounts of space. * Font optimization: We strip out unused font data. * Structure Cleanup: We remove redundant metadata and tags.

When to Compress * **Emailing:** Most servers have a 25MB limit. Compression keeps you under the radar. * **Web Uploads:** Faster loading times for users viewing PDFs on your website. * **Archiving:** Save disk space when storing thousands of documents.
