The Free Smallpdf Alternative
Smallpdf is a polished product — but the free tier locks you out after two operations per day and pushes hard on a paid subscription. PDFkill gives you every operation, every day, free forever — with files deleted from our servers the second you download them.
Why people switch from Smallpdf to PDFkill
No daily limit
Smallpdf caps free users at 2 documents per day. PDFkill has no daily limit. Process 200 PDFs today, 200 tomorrow.
No account, ever
Smallpdf nudges you toward a free account, then a paid one. PDFkill never asks for an email — you can finish your task without ever revealing who you are.
Stronger privacy default
PDFkill deletes your file the second your download starts, in-memory, no logging. No "stored for 7 days" data retention policy.
Faster on average
PDFkill averages under 5 seconds per operation. No pre-processing queue, no upsell modal between upload and download.

Common questions
Is PDFkill really free, or is there a hidden catch?+
There is no catch. Every tool is free with no daily limit and no account. Costs are covered by non-intrusive ads on marketing pages — never on the tool pages themselves.
How does PDFkill compare to Smallpdf Pro?+
PDFkill matches the core features of Smallpdf Pro (unlimited operations, no watermark, no daily cap) at $0/month instead of $9/month. Smallpdf Pro adds OCR, e-signing, and team management — we don't do those yet.
Can I trust PDFkill with sensitive documents?+
PDFkill is built privacy-first: uploads use 256-bit TLS, files are processed in memory, and your file is purged from the server the moment your download begins. We don't store, log, or share your files.
Why is PDFkill free when Smallpdf charges?+
We have lower overhead (no salesforce, no CSAT team, no enterprise tier) and run lean. The ad revenue from marketing pages covers our server bill. We have no plans to add a paid tier.
