Sejda vs WhiskFile
Sejda is a capable PDF tool suite, but its 5-task-per-hour limit frustrates many users — especially when you hit it mid-workflow. WhiskFile offers 7 free tasks per day with no hourly throttle, plus 20+ additional tools Sejda doesn't have, and AI features Sejda lacks entirely.
- Daily limit (7/day) is less disruptive than hourly throttling
- 20+ exclusive tools (split by bookmarks, split by text, Bates numbering, e-signature, form builder, workflow automation, etc.)
- AI features: PDF Summarize, PDF Chat, Auto-Redact PII (Pro)
- Team workspace with shared billing
- REST API with 38 endpoints
- Desktop app available (Mac, Windows, Linux)
- 28-language support with hreflang
- Slightly cheaper Pro plan
- Established product with 10+ years of users
- 5-task-per-hour limit frustrates batch workflows
- No AI features
- No team/organization plan

We compare publicly documented features, limits, pricing, supported formats, integrations, account requirements, and privacy information.

Frequently asked questions
WhiskFile has more tools (101 vs Sejda's ~35), AI features Sejda lacks, and a less disruptive daily limit (7/day vs 5/hour). Sejda has a desktop app and has been around longer. For most web-based workflows, WhiskFile is the stronger choice.
Sejda's 5-task-per-hour limit resets every 60 minutes. If you process 6 documents in an hour — common for batch work or multi-step workflows — you hit the wall suddenly and must wait. WhiskFile's 7-per-day limit is less likely to interrupt a focused work session.
WhiskFile Pro is $4.99/month vs Sejda's ~$7.50/month, a $2.51/month difference. WhiskFile Pro includes AI features and batch processing not available on Sejda at any price.
No. WhiskFile is a web-based tool. Sejda has a desktop app for offline use. If offline access is essential, Sejda's desktop app or a locally installed tool like PDF24 may be a better fit.
No. WhiskFile does not add watermarks on the free plan — the same as Sejda. Watermark-free output is available to all users, logged in or not.
Sejda does not offer batch processing on any plan. Each file must be processed individually. WhiskFile Pro includes batch processing for merge, compress, convert, and other tools.
Yes. Both WhiskFile and Sejda offer OCR. WhiskFile OCR is free for all users with 100+ languages. Sejda's free OCR is limited to 10 pages per task; paid plans allow up to 100 pages.
WhiskFile auto-deletes uploaded files after 1 hour, with most tools processing directly in the browser (files never leave your device). Sejda states files are deleted, but the exact timing is not clearly documented.
Sejda has minimal AI functionality — a basic chatbot for support. It does not offer AI PDF summarization, AI chat with documents, or automated PII redaction. WhiskFile Pro includes all of these.
WhiskFile offers 101 tools compared to Sejda's ~35. WhiskFile includes tools Sejda lacks: split by bookmarks, split by text, Bates numbering, rename from content, e-signature, form builder, workflow automation, and image editing tools.
Conclusion
Sejda is a solid PDF tool with a desktop app and 10+ years of trust. However, its hourly task throttle, missing AI features, and lack of team plans make WhiskFile the stronger choice for batch workflows, AI-assisted tasks, and small teams. If you need offline desktop access, Sejda still has the edge.
