If you've tried compressing PDFs by zipping them, you know it doesn’t always deliver the results you’d hope for.
You’re not alone in wondering, "Does a PDF compress much in a ZIP file?" The short answer? Not as much as you’d expect. But why is that, and is there a better solution?
Yes, of course, and this post will tell you why ZIP compression isn’t the most effective way to compress PDF files, explain alternatives like Smallpdf’s Compress PDF, and show you how to securely reduce your PDF sizes without compromising quality.
Why Doesn’t ZIP Compress PDFs Much?
ZIP compression works wonders for many file types by finding patterns and redundancies in raw data. However, when it comes to PDFs, the results are often disappointing. Here’s why:
- PDFs are already compressed PDFs often come pre-compressed, particularly when created through modern software. This leaves little room for additional size reduction.
- Frequency of embedded content PDFs can contain images, fonts, formatting, and other rich media. These components are often highly optimized already, making ZIP compression less effective.
- Uncompressed elements matter If a PDF includes uncompressed or high-resolution images, the ZIP format may reduce the size slightly. However, if most elements are compressed, improvements will be minimal.
The takeaway? Zipping a PDF might save you a few bytes, but it won’t give you the drastic size reduction you’re looking for.
Smallpdf Compress PDF vs. ZIP Compression
While ZIP compression isn’t the best way to make a PDF smaller, specialized tools like Smallpdf’s Compress PDF shine by targeting specific areas of a PDF for optimized reduction.
How is Smallpdf Different?
Our tool doesn’t bundle files into an archive like a ZIP. Instead, it directly works within the PDF structure to: 1. Re-encode images
Large, high-resolution images are re-encoded to reduce their size while keeping the quality. For example, a 300 DPI image can be downscaled to a web-friendly 150 DPI.
- Remove redundant data
Metadata and unnecessary file components are stripped away, leaving only what’s essential.
- Optimize fonts and layouts
Smallpdf compresses embedded font files and streamlines layout data, which helps maintain the document’s structure without wasting space.
With this tailored approach, you get smaller PDFs that retain their readability and quality, something ZIP compression simply can’t do.
