Alternative for Mac
A Smallpdf alternative for Mac
What Smallpdf does well
Smallpdf, built in Switzerland, is one of the most approachable PDF suites around. It has more than 30 tools, built-in e-signing, and it connects to cloud storage like Dropbox and Google Drive. A Pro subscription lifts the free tier's daily download limit and adds OCR, strong compression and batch convert.
It works in any browser plus mobile and desktop apps, so it's a reasonable pick if you need PDF tools across different devices.
Where Fileknife is different
As with other web tools, Smallpdf uploads your file to the cloud to process it. Fileknife keeps everything on your Mac, which matters for a confidential document or anything you'd rather not hand to a third-party server.
Fileknife is a one-time purchase instead of a subscription, with no daily limit and no upload queue, and it runs from Finder's right-click menu. It isn't cross-platform and it won't match every Smallpdf feature, so if you need reach and e-signing, Smallpdf is the better fit.

What I tested
I compressed a 40 MB scanned PDF to about 4 MB in Fileknife, entirely on the Mac. Smallpdf does this well too; the difference is the upload, not the result.

Questions
Is Smallpdf free?
It has a free tier with a daily download limit, plus a Pro subscription for unlimited use, OCR and batch tools. Fileknife is a one-time purchase with no daily cap.
Does Smallpdf keep my files private?
Smallpdf processes files in the cloud, so your document is uploaded and deleted after a period. Fileknife never uploads: the work happens on your Mac.
Does Fileknife have e-signing like Smallpdf?
No. Smallpdf includes e-signing. Fileknife focuses on local PDF jobs such as compress, merge or split, OCR and images to PDF.
Which is cheaper over time?
Smallpdf Pro is a recurring subscription. Fileknife is paid once. If you use PDF tools regularly for years, a one-time purchase usually costs less overall.
Can I use Fileknife offline?
Yes. Fileknife works with no internet connection, because everything runs on your Mac. Smallpdf needs a connection to upload and process the file.
Smallpdf or Fileknife for a confidential document?
Fileknife, for anything you'd rather not upload. It processes the file on your Mac, so a contract or ID scan never leaves the machine. Smallpdf sends it to the cloud first.
