Does compressing a PDF make the text blurry?

No. Text stays sharp because it is vector data. The savings come from re-compressing embedded images, which you can tune by quality level.

Can I compress a PDF without uploading it?

Yes. A desktop tool like CompressEasy processes the PDF entirely on your computer, so confidential documents are never uploaded.

How to compress a PDF without losing quality

A large PDF is annoying to email, slow to upload, and wastes storage. The key to shrinking it well is understanding where the weight actually comes from, and choosing a method that keeps your document private.

PDF weight comes from images, not text

Text in a PDF is tiny. What makes a PDF heavy is high-resolution embedded images and scanned pages. That means the most effective way to shrink a PDF is to downsample and re-compress those images, while leaving the text untouched and crisp.

Choose a target resolution

Pick a DPI that matches how the PDF will be used:

Around 300 DPI for high-quality printing.
Around 150 DPI for comfortable on-screen reading.
Around 72 DPI for quick sharing where small size matters most.

Why most online PDF tools are a privacy risk

The majority of free PDF compressors upload your file to their servers to process it. For contracts, invoices, medical records, or client work, that means handing a sensitive document to a third party. A local tool avoids this entirely.

Compress PDFs on your own computer

CompressEasy Desktop compresses PDFs locally by optimizing the embedded images, so the file gets much smaller while your document never leaves your machine. You choose the quality level depending on whether the PDF is for print, screen, or quick sharing.
