Compress & Optimize PDF Files Online

Reduce PDF file weight directly in your browser. Choose between safe structural cleanup (preserving selectable text and vectors) or optional raster compression for scanned/image-heavy documents, with honest before-and-after byte metrics.

How to Use This Tool

  1. 1

    Upload Your PDF File

    Select or drop your PDF document. We immediately display its exact original file size and page count.

  2. 2

    Select Optimization Mode

    Choose 'Structural Optimization (Lossless)' to strip unused objects and compress PDF object streams while keeping text selectable, or 'Rasterize Pages (Lossy)' with your desired quality level for scanned PDFs.

  3. 3

    Process & Compare Sizes

    Run the optimization locally and review the exact original size versus final size and percentage change.

  4. 4

    Download the Optimized File

    Download the resulting PDF. If structural optimization cannot shrink an already compact file further, we clearly inform you.

Key Features & Capabilities

Clear Distinction: Structural vs. Raster

Structural mode cleans unused objects, removes metadata overhead, and packs PDF streams losslessly. Optional Raster mode renders pages as compressed images at selectable DPI/quality.

Transparent Quality Warnings

When selecting optional rasterization, the interface clearly warns that visual sharpness decreases and selectable text/hyperlinks are flattened into images.

Honest Size Reporting

We never fake compression metrics. You see the exact byte count before and after processing, and we alert you if a file is already maximally optimized.

100% Local Processing

Both structural stream packing and canvas rasterization occur strictly inside your browser without uploading files.

Frequently Asked Questions

Structural Optimization reorganizes internal PDF object streams, strips redundant metadata, and removes unreferenced objects without altering text or image quality. Rasterization converts each page into a compressed JPEG image inside a new PDF—ideal for heavy scanned documents, though it flattens selectable text.
