Quick answer
Open Compress PDF in Chrome, choose the PDF from the file picker, pick a mode, and download the smaller version.
Step by step
- Open Chrome and go to Compress PDF.
- Choose "Structure Only" for text PDFs or "Rasterize & Recompress" for scans and photos.
- Tap the drop area. In the file picker, look in Recent, Downloads or Google Drive to find your PDF.
- Compare the sizes shown, then tap the download button.
- Chrome shows a notification when the download finishes. Tap it to open the file, or find it later in the Downloads section of your Files app.
Tips
- Photos of documents turned into PDF are heavy. "Rasterize & Recompress" with a lower quality setting shrinks them the most.
- Turn your phone to landscape if you want the buttons and the preview to be larger.
- Keep the original file until you have checked the compressed copy.
