Pages are re-rendered as images, so text becomes non-selectable. Best for scanned documents and certificates.
Quick answer: To reduce a PDF’s size: choose the PDF, pick a level (Balanced is a good start; Strong for the smallest file), tap Compress and Download. If it’s still too big, try Strong.

Frequently asked questions
Why can’t I select text after compressing?
To shrink scans, each page is re-drawn as an optimised image. For text-only PDFs the original is often already small — the tool keeps the original if it can’t make it smaller.
Is it safe for Aadhaar and certificates?
Yes. The PDF never leaves your device.
Is it free? Is there a watermark or limit?
It is completely free with no sign-up, no watermark and no daily limit.
