Mobile Productivity: Shrink PDFs on the Go

Whether you're on a train or in a meeting, needing to shrink a PDF on your phone used to mean downloading a sketchy ad-filled app. Not anymore.

For iPhone (Safari):

Simply navigate to adobepdf.in/tools/compress-pdf, tap the upload icon, select your file from the "Files" app, and hit compress. Safari's modern engine handles the processing perfectly.

For Android (Chrome):

The process is identical. Chrome for Android supports the necessary JavaScript to perform local compression, meaning your data stays on your phone.

This method is safer and faster than using third-party "free" apps from the App Store or Play Store that often sell your data.
