Compress a PDF in Chrome (30 seconds)
No account, no permission prompts beyond file access.
- 1. Open Chrome and go to shrinklyy.site → pick your target (e.g., 500 KB for email, 200 KB for a portal).
- 2. Tap ‘Choose file’ → Browse → select the PDF from Downloads, Google Drive, or Files.
- 3. Wait a few seconds while your phone processes locally → tap Download.
- 4. The compressed file appears in Downloads. Open it once to confirm small text is crisp, then share via email, WhatsApp, or upload to the portal.
Finding the right file on Android
Android stores PDFs in several places. If you can’t see the file:
- Check Downloads first: scans and Drive downloads land there.
- Use the Files app → Documents → PDFs to browse by type.
- If the PDF was shared via WhatsApp, look in WhatsApp → Media → WhatsApp Documents.
- From Drive: open the PDF → ⋮ → Download, then pick that downloaded copy for compression.
Scanning directly on Android
Drive has a built-in scanner (Drive → + → Scan). It crops and straightens and saves a reasonable-size PDF. Use that instead of a plain photo: the source is cleaner and compresses better.
For best results, set scan to grayscale if colour is not required, and use good even lighting to avoid shadows.
Frequently asked questions
Quick answers to the questions readers ask most about this topic.
Yes, but large PDFs (20+ MB) take longer because processing uses your phone’s CPU. For big files, try 500 KB target or Custom → Medium first, which is faster than Maximum.
You still download a local copy | Shrinklyy reads the file from your device. In Drive, download once, then compress that copy. It stays in your Downloads and does not change the Drive original.
In Downloads, named like ‘original-compressed.pdf’. Files app → Downloads shows it, and Chrome’s download bar has an Open button right after download.
