Free PDF optimization tools
Make your PDF files smaller and easier to share without losing readability. Our optimization tool shrinks bulky documents so they slip under email limits and upload faster, while keeping text and images clear — and it all happens inside your browser.
Reach for this when a PDF is simply too big: an attachment your email rejects, a form an upload page will not accept, or a scan that takes forever to send. Compressing the file reduces its size while keeping it perfectly usable, so you can share it anywhere with confidence. Because the work is done locally, your document is never uploaded and stays completely private, no matter how large it is.

Frequently asked questions
Will compressing my PDF make it look worse?
No. Compression is designed to reduce file size while keeping the document clear and readable, so it stays perfectly usable for email and printing.
Is there a file size limit?
There are no daily limits. Because the file is processed on your own device, you can compress large documents privately without uploading them anywhere.
