How to Compress a PDF Online
Compressing a PDF shrinks its file size by optimizing images, removing redundant data and re-encoding content, making it easier to email, upload and store. This free PDF compressor runs entirely in your browser, so your documents never leave your device. Simply drag in one or more PDF files, choose a quality level, and download the compressed result in seconds. It works with scanned documents, reports, ebooks and forms, and you can batch-compress multiple files at once without any watermark or registration.
When to Use a PDF Compressor
Use a PDF compressor when your file exceeds an email attachment limit, an upload form's size cap, or a storage quota. Compressing is also smart before printing or archiving, since a leaner file transfers faster and takes less space. For documents full of images, aggressive compression saves the most space; for text-heavy files, a moderate setting preserves crisp text while still shrinking the size. Because everything is processed locally, sensitive contracts and personal documents stay private throughout the process.
