Make PDF files smaller online for free. Quick and easy PDF size reduction for email attachments, uploads, and storage.
Use This Tool Free — No SignupNeed to make a PDF smaller so it fits in an email or meets an upload requirement? Our free tool does exactly that — quickly, easily, and without any fuss. Just upload your PDF and get a smaller version back. It is the simplest way to deal with oversized PDF files. Common situations where you need a smaller PDF include sending email attachments (many email services limit attachments to 10-25 MB), uploading to web portals with file size restrictions, sharing via messaging apps, storing documents efficiently in cloud storage, and distributing files to people with slow internet connections. Our tool addresses all these situations by optimizing your PDF to the smallest practical size. The reduction happens through a combination of image optimization, font subsetting, metadata removal, and structural cleanup. You get a professionally optimized PDF that is ready to share, store, or upload wherever you need it.
