Why Users Are Leaving Sejda
3 Tasks Per Hour Throttle
Sejda enforces a strict hourly rate limit, forcing you to wait 60 minutes after performing just 3 quick document edits.
50MB and 200-Page File Caps
Larger PDFs, high-res scans, or extensive books fail to process on Sejda's free tier due to rigid file size limits.
Temporary Cloud Storage Window
Files remain on Sejda's servers for up to 2 hours before automated deletion, creating a vulnerability window for sensitive corporate data.

Frequently Asked Questions
Why does Sejda have an hourly limit while Hearthhammer does not?
Sejda uses cloud servers that cost money per CPU cycle, so they limit free users to save server costs. Hearthhammer utilizes your computer's own browser engine, allowing unlimited usage without throttles.
Can I use Hearthhammer offline?
Once the webpage loads in your browser, all PDF manipulation algorithms run locally even if your internet connection fluctuates.
