About this tool
Compression is almost always about a limit somewhere else. The email attachment cap, the portal that rejects anything over 10 MB, the form that wants "under 2 MB," the folder of scans eating your storage. Three presets here: High quality when the document still has to print well, Balanced for everyday sharing, and Smallest when there's a hard cap to get under. Before and after sizes show up immediately, with a preview, so you can judge the tradeoff yourself.
Under the hood, PDFium (the engine behind this site's editor) re-renders each page at the preset's resolution and rebuilds the document around efficiently compressed images. That approach works best on exactly the files that tend to be bloated: scans, photographed documents, image-heavy decks, where 60-90% reductions are normal. The catch is that rebuilt pages are images, so text that was selectable stops being selectable. The tool notices when that's about to happen and warns you before the download, not after.
There's no upload queue, no daily limit, and no server holding a copy of your contract while it shrinks. If the result ever comes out bigger than the original, which can happen with already-optimized digital PDFs, the single-file view says so plainly instead of serving you a worse file behind a green checkmark (convert files one at a time to see the before/after sizes). Either way your original isn't touched; the compressed copy downloads under its own name.
