Why 100 KB is the size that trips people up
100 KB is one of the tightest limits an upload form will set. Older job portals, some scholarship and admission forms, and a lot of internal document systems still cap a PDF upload at 100 KB, and they reject anything larger without explaining how to fix it. That is usually the moment someone goes looking for a way to compress a PDF to exactly that size.
Getting under 100 KB is easy for a text document and hard for a scanned one. A few pages of plain text carry very little data, so they drop under 100 KB with room to spare. A scan, which is really a photograph of each page, carries far more, and squeezing it that small means visibly softer images. This tool works down through progressively stronger settings and stops at the first one that fits, so a text PDF keeps most of its sharpness while a heavy scan is compressed as far as it needs to go.
What to expect for your file
There is no fixed ratio, because the result depends on what your PDF contains. Rather than promise a percentage, this tool compresses your actual file and reports the real size it reached. If your PDF cannot physically reach 100 KB without becoming unreadable, it hands you the smallest version it could make and tells you plainly, so you are never left guessing whether it worked.
Everything happens in your browser. The file is never uploaded, which matters because the documents people squeeze to 100 KB are often identity documents, certificates, and application forms. You can watch your browser's Network tab while you compress: nothing leaves the page.
