YOUR GUIDE TO THIS TOOL

What is Compress PDF and when is it useful?

Large scanned PDF documents can fail email and portal upload limits. This tool re-renders pages into compressed image-based pages to reduce file size; it is most useful for scanned or photo-heavy PDFs where selectable text is not essential.

Who can use this tool?

These are a few practical situations where the tool may save time:

Applicants uploading scanned certificates
Office staff emailing bulky PDF attachments
Users sharing phone-scanned documents
Businesses preparing smaller reference copies

How to use Compress PDF

Choose a PDF, preferably one with scanned images.
Select image quality and render resolution.
Process the document and download the new PDF.
Compare readability and file size before using the compressed version.

Before you download: things worth checking

This processing method can remove selectable text, links and searchability.
A text-only PDF may actually become larger after rasterization.
Always retain an original if it contains signatures or archival content.

Your input file remains on your device with the current browser-processing workflow. Save the result separately and check it yourself before uploading it to any official portal, printing it or sending it to someone else.

Questions people ask about Compress PDF

Will the file definitely get smaller?

No. Results depend on the input; text-based PDFs may not shrink.

Can I search text in the output?

Not reliably, because pages are rendered as images.

What quality should I start with?

Balanced quality is a sensible first test for scanned documents.
