Frequently asked questions
Why is the file still over 80 KB?
Usually because of images, scans, or embedded fonts, which can need more than 80 KB even after strong compression. Choose High and check the estimate. If the file is still over, compress the result again at High or remove pages you don't need.
Will a short letter fit into 80 KB?
Usually, yes. A one- or two-page letter that is mostly text often fits into 80 KB, sometimes even at Low or Medium. A letterhead with a large logo or a scanned signature adds weight, so choose High if the estimate is still over.
Why does the size stop dropping before it reaches 80 KB?
Because some data can't be squeezed much further. Images that are already compressed, scanned pages, and embedded fonts reach a point where more compression barely helps. Compressing the result again at High may gain a little. If not, remove pages you don't need or use smaller images.
Can I reduce a PDF to 80 KB on a phone or tablet?
Yes. Open PDFFly in your phone or tablet browser, upload the PDF, choose a level, and download the result. You can reduce PDF to 80 KB this way with nothing to install, then share the file from the same device.
Will the compressed PDF remain readable?
Text usually stays readable, even at High. Images lose the most detail under strong compression and may look blurry, so a text-heavy document fares much better than a photo-heavy one. Open the downloaded file and check small print before you send it.
