How to resize a PDF document using Smallpdf

Once you upload your file, the Smallpdf compress tool will detect and replace repetitive patterns within your data with lighter identifiers. This means, the content should remain intact (fonts, page size, colors), with the PDF size being much, much smaller.

But Where Does the Original File Go?


Your file is uploaded to our servers, where we compress it. Afterward, we’ll make sure that the file is permanently deleted from our servers after one hour of processing. During this time, nobody else will have access to the file except for the sole user—you! Still, Smallpdf wants to enable easy sharing and collaboration for your digital document needs. Because of this, once you resize your PDF, you can also share it via email or generate a shareable link directly on the result page.

Do More With the Resized PDF


If you think quickly resizing and cutting a PDF file down to a fraction of its original size is incredible, the fun doesn’t stop there. You can also resize PDFs on the go with the Smallpdf Mobile App! On our homepage, you’ll also find 20+ amazing PDF tools for you to convert, modify, and even sign your digital files.

That’s right—you can access every single tool for free for up to two tasks a day. If you work regularly with digital documents, you should check out Smallpdf Pro. You can sign up for a 7-day free trial anytime.

A subscription will give you unlimited access to the resize PDF tool and unlock many other perks. Having a paid account will allow you to resize many PDFs in one go, up to 5GB. You’ll also get full access to our offline desktop app.
