PDF24 is a popular free PDF service from Germany. Like ShrinkBeam it is free and has no usage limit. The difference is where your file is processed: the PDF24 online tools upload it to a server, and the offline PDF24 Creator only runs on Windows. This page compares both on these points.

| Price and limits | Free, no limits; financed by ads on the website | Free, no limits |
| Account | Not required | Not required |

When ShrinkBeam is the better fit
Choose ShrinkBeam when you want to keep a document on your device but are not on Windows, cannot install software (for example on a work laptop or a Chromebook), or are on your phone. Compression, merging, splitting, sorting pages, signing, password protection and redaction run locally in the browser.
When PDF24 is the better fit
On a Windows PC where you may install software, the free PDF24 Creator also works offline and offers more functions, including a virtual PDF printer and Office conversions. The PDF24 online tools also cover Office formats, which ShrinkBeam does not.
How to switch
Open the matching ShrinkBeam tool, select your PDF and start. Compare the size of the download and open it before sending. Keep your original until you have checked the copy.
