🗜️ PDF Compress

Reduce PDF file size — best for scanned/image-heavy PDFs.

This works by re-rendering each page as a compressed JPEG image — best for scanned or image-heavy PDFs. Text will no longer be selectable in the output.

📋 How to Use

1. Upload the PDF you want to shrink.
2. The tool re-renders each page as a compressed image internally to reduce size.
3. Download the smaller file once processing finishes.

✅ Features

Best results on scanned or image-heavy PDFs, where file size is dominated by images.
Adjustable compression level to balance size against visual quality.
Honest trade-off noted upfront: this reduces text sharpness slightly, since pages are re-rendered as images.

Make PDF files smaller

PDFs with scanned pages or many images can easily reach 10–50 MB, which is too large for email and many upload forms. This PDF compressor reduces the file size so you can share and upload documents without errors.

When it helps most

  • Online applications for jobs, universities, visas and banks that limit file size.
  • Emailing documents that exceed the attachment limit.
  • Saving storage space on your phone or cloud drive.

What to expect

Scanned documents and image-heavy PDFs usually shrink the most, because images take up most of their size. PDFs that are mostly plain text are already small, so they may not shrink much further. Very strong compression can make small text in scans harder to read, so open the result and zoom in before you submit it.

Tip: if a portal still rejects the file, try splitting it into smaller parts with the PDF Split tool, or scan at 150–200 DPI instead of 600 DPI next time.

Frequently Asked Questions

Why does the compressed PDF look slightly less sharp?
Compression works by re-rendering each page as a re-encoded image at a smaller size, which is what actually reduces the file size — that process can soften fine text and detail slightly, especially at higher compression levels.
Is this compressor better for scanned documents or design files?
It works best on scanned or image-heavy PDFs, where large images are the main cause of file size. For text-heavy, non-scanned documents, the size savings are typically smaller since text itself is already small.
