How to reduce pdf size without losing quality
- 1. Compress with the lighter setting first.
- 2. Read text and look at a photo at the size you will send.
- 3. Stop when another pass hurts the page more than it helps the byte count.
Quality in a PDF is not a single slider. Text drawn as text stays sharp at any zoom. A scan is a grid of pixels, and making that grid smaller is what reduces size. The loss shows up in photos and in small type that was never real text. Start with the lighter pass. Read a heading and a signature. Only then try a stronger pass. If the new file is not smaller, keep the original. That rule prevents a “compression” that only adds a second blurry copy.
There is no honest score that says 92 percent quality unless something measured the pages. This app does not invent that score. Your eyes on the actual page are the check. The work this guide points to stays in the browser. No upload is required to follow it.
Reduce PDF size without losing quality stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
