What Is a PDF Compressor?

A PDF compressor reduces the size of a PDF document so it can be easier to store, share, upload, or send as an attachment. Compression can be especially useful for PDFs containing scanned pages or large images.

EasyTools365 uses a browser-based approach that rebuilds PDF pages as compressed images. Because of this, the tool is best suited to scanned and image-heavy documents rather than text-heavy PDFs that need their original vector structure preserved.

How to Compress a PDF

  1. Select a PDF file or drag it into the upload area.
  2. Choose Low, Medium, or High compression.
  3. Click Compress PDF.
  4. Wait while each page is processed in your browser.
  5. Review the original size, new size, and saved percentage.
  6. Download the compressed PDF if the result meets your needs.

Which PDF Files Work Best?

This compressor works best for scanned documents, scanned forms, image-based reports, and PDFs containing many photographs. These files often contain large raster images that can benefit from JPEG compression.

Results vary according to the original document. A PDF that is already highly compressed may become only slightly smaller or may even become larger after rebuilding.

PDF Compression Levels

Low

Uses higher image quality and is useful when visual quality is more important than maximum size reduction.

Medium

Provides a balance between image quality and file size and is the default setting.

High

Uses stronger compression to target a smaller output file.

Local Processing

The selected PDF is processed in the browser rather than uploaded to the EasyTools365 server.
