The Sejda alternative with no daily task limit
Sejda is one of the more honest tools in this category — parts of it can even process files in your browser, and its pricing (day and week passes rather than only subscriptions) respects occasional users. But the free tier's task and size limits arrive fast, and knowing which tool runs locally versus on Sejda's servers takes careful reading. PDFAirlock removes both frictions: every tool is local, always, enforced by the site's security policy — and there are no limits at all during beta.
Why people look for a Sejda alternative
- The free daily task or file-size limit keeps interrupting real work
- You can't tell which Sejda tools process locally and which upload — and the document is sensitive
- You'd rather verify privacy (network tab, wifi off) than parse a features matrix
- You want verified redaction with a report
What Sejda does better
Honest credit: Sejda has a genuine in-browser PDF text editor — editing existing text in a PDF is hard, rare, and useful, and we don't do it. Its desktop app and its pass-based pricing are both user-respecting choices, and the fact that some of its web tools run client-side puts it closer to our philosophy than any other incumbent.

Frequently asked questions
What are Sejda's free limits?
Sejda's free tier restricts tasks per day and document size, which is fair for their costs — server processing isn't free. PDFAirlock has no per-task costs because your browser does the work, so there are no task limits.
Does Sejda upload my files?
It depends on the tool — Sejda documents that some tools run in-browser while others process on its servers. PDFAirlock is simpler to reason about: everything is local, and the site's Content-Security-Policy makes server contact impossible, which you can verify yourself.
Can PDFAirlock edit PDF text like Sejda?
No — Sejda's text editor is genuinely its standout feature and we credit it. PDFAirlock covers everyday operations (merge, split, compress, redact, sign, protect) rather than in-document editing.
