Got a PDF that's too big to email or share on WhatsApp? This tool shrinks your PDF's file size in seconds — entirely inside your browser, so your document never leaves your device. Works on phone or desktop, no account needed.
Open This Tool Free →No. Compression happens entirely in your browser using JavaScript — your file is never sent to any server.
You can choose the compression level. Lighter compression keeps quality nearly identical; higher compression shrinks size further with some quality trade-off.
No artificial limit is imposed by the tool — very large files may just take a little longer since everything runs on your own device.
