Smallpdf is one of the most-searched PDF tools online, with 30+ features behind a freemium gate. The free tier is famously stingy: 2 tasks per day, watermarks on output above ~5 MB, and an aggressive Pro upsell. If you mostly need merge or split, a free Chrome extension is a much faster path.
Free Local Alternative — No 2-Task Limit
PDF Merge & Split runs entirely in your browser. No account, no upload, no watermark.
Add to Chrome — FreeWhy Smallpdf's free tier feels limiting fast
Even moderate users hit Smallpdf's ceilings within a week:
- 2 tasks per 24 hours on the free plan (a "task" is a single conversion, merge, or split).
- Watermark above ~5 MB on the free tier — and a typical scanned tax document is 8-15 MB.
- $108/year Pro for unlimited tasks, which is steep for occasional use.
- Login wall after 2 free tasks even within the same day.
If you only ever need merge or split, paying for Pro just to lift the limit is a bad value.
Where the extension wins
The Chrome extension is purpose-built around merge and split with no artificial caps:
- Unlimited tasks. No counter, no login, no daily reset.
- No watermark at any file size.
- No upload — everything happens locally in the browser tab.
- Free forever for the core features.
The downside is feature scope. The extension does merge, split, reorder, and rotate. Smallpdf does ~25 things including PDF-to-Word, compression, e-sign, and OCR. For those, Smallpdf or Acrobat remain the better fit.
A typical week before and after switching
Realistic weekly usage for a knowledge worker:
- Combine 3 invoice scans into one expense report (1 task)
- Split a 50-page board pack into 5 sections for individual share (1 task)
- Reorder pages of a contract before sending to client (1 task)
- Rotate a sideways scan back to portrait (1 task)
That is 4 tasks per week, which on Smallpdf's free tier means hitting the daily limit twice and getting prompted to upgrade. With the extension, all four take under a minute each and never trigger an upsell.
When Smallpdf is still worth it
Stay on Smallpdf if you regularly need:
- PDF-to-Word or PDF-to-Excel conversion (the extension does not).
- OCR on multi-language scanned documents.
- E-signing PDFs with a signature panel.
- Compressing PDFs aggressively for email attachments.
For everyone else, the extension covers the daily 80% and frees up your Smallpdf quota for the harder tasks.

Frequently Asked Questions
Why does Smallpdf put a watermark on my output?
On the free tier, files above an internal size threshold (typically ~5 MB) get a watermark added in the corner of every page. The watermark is removed on the Pro tier.
Is the Chrome extension as polished as Smallpdf?
For the merge/split/reorder/rotate flow, yes — the UI is comparable. For everything else, Smallpdf has more features and a more polished marketing site.
Can I use Smallpdf and the extension together?
Yes. Many users use the extension for daily merge/split (saves Smallpdf quota) and Smallpdf when they specifically need a feature the extension does not have.
Does the extension work in Edge or Brave?
Yes. Any Chromium-based browser supports it: Chrome, Edge, Brave, Arc, Vivaldi, Opera.
Will my Smallpdf workflow port directly?
For merge, split, reorder, and rotate — yes, identically. For PDF-to-Word, e-sign, or compression, you would still need Smallpdf or another dedicated tool.
