How to Compress PDF in Google Drive (2026 Guide)

Important: Google Drive does not have a built-in PDF compression feature. To compress a PDF for Google Drive, you need to compress it first using a tool like DocMint, then upload the smaller file.

The Best Way: Compress with DocMint, Then Upload

Go to DocMint Compress PDF — free, no signup
Upload your PDF (drag & drop or click to browse)
Select Medium compression for the best quality-to-size ratio
Click Compress PDF and download the smaller file
Upload the compressed PDF to Google Drive

This typically reduces PDF size by 50-80%, saving significant Google Drive storage.

Privacy note:

DocMint compresses PDFs in your browser — your file never gets uploaded to DocMint's servers. Only the compressed result is downloaded to your device before you upload to Google Drive.

Why Compress PDFs Before Uploading to Google Drive?

Save Storage Quota

Google Drive gives you 15 GB free, shared across Gmail, Drive, and Photos. Large PDFs eat into this quota quickly. A folder of 50 scanned documents at 5 MB each = 250 MB. Compressed to 1 MB each = 50 MB. That's 200 MB saved.

Faster Uploads and Downloads

Smaller files upload faster, especially on slow connections. Compressed PDFs also load faster when shared with others via Drive links.

Easier Sharing

When you share a Google Drive link, recipients download the file. Smaller files are more considerate of their bandwidth and storage.

Compression Levels — Which to Choose?

Low compression: 10-30% size reduction — use for print-quality documents you need to preserve
Medium compression: 50-60% size reduction — best for most Drive storage use cases
High compression: 70-90% size reduction — use for archiving documents you rarely need to view at high quality

Compress PDFs Already in Google Drive

If you have PDFs already stored in Google Drive that you want to compress:

Download the PDF from Google Drive
Compress it with DocMint
Delete the original from Google Drive
Upload the compressed version

Other Ways to Save Google Drive Storage

Remove metadata: Strip hidden metadata from PDFs before uploading — can reduce size by 5-15%
Remove blank pages: Delete unnecessary pages before uploading
Convert to PDF/A: PDF/A format is optimized for archiving and often smaller than standard PDFs

FAQ

Can Google Drive compress PDF files?
