AI features the basics don't include
Sejda covers conversion, merging, and basic edits. PDFSub adds AI summarization, translation across 130+ languages, chat-with-PDF, table extraction, and handwritten-document conversion - same plan, no add-ons.

Best Sejda Alternative
Why teams move from Sejda to PDFSub - and how to switch in under an hour.
Why teams switch from Sejda
Files stay on your device
Most consumer PDF tools upload everything to their cloud. PDFSub processes ~28 of its 84+ tools entirely in your browser - files never leave your device. Important for HR docs, financials, legal materials, and contracts under NDA.
84+ tools vs the typical 12-20
Tools like Sejda top out at 15-25 features. PDFSub includes rare conversions (EPUB, SVG, ODP, ODG, RTF), specialty workflows (bank statements, photo-to-document), and AI extraction - fewer tabs, fewer subscriptions.
E-sign included, no per-envelope fees
Sejda usually treats e-sign as a separate product (or doesn't offer it). PDFSub includes unlimited e-sign and form filling on every paid plan - no per-envelope fees like DocuSign.
Reported by Sejda reviewers
Users repeatedly ask Sejda to lift the 3-tasks-per-day free cap (suggestions to raise to 5-8 are common); the 10-page OCR cap on free tier is also flagged as too restrictive for real-world use.
Disclaimer: The summary above reflects published opinions of third-party reviewers on public review sites (such as G2, TrustPilot, Capterra, BBB, and PissedConsumer). These are reviewers' opinions, not PDFSub's assessment of Sejda, and they may not reflect your experience or current product behavior. We surface this information so readers can make an informed decision; please verify directly with Sejda before drawing conclusions.

Full access to all 84+ tools and 250 AI credits to test the AI features.
- 3

PDFSub now handles your PDF work plus AI features and bank statement conversion in one subscription.
Common questions about switching
Will my Sejda PDFs work in PDFSub?
Yes. PDFs are a universal format - there's no Sejda-proprietary lock-in. Every PDF works in PDFSub regardless of which tool created or edited it previously.
Is e-sign really included with no per-envelope fees?
Yes. Unlimited e-signatures and form filling on every paid PDFSub plan. No per-envelope fees like DocuSign's $25-65/user/month model.
What if Sejda has a feature I depend on?
For most users, PDFSub's 84+ tools cover everything they actually use. The exception is highly specialized desktop features (Action Wizard, JavaScript automation, pre-press workflows in Adobe Acrobat). If you depend on those, run a 7-day trial first to confirm fit.
Does PDFSub work offline?
PDFSub is a web app - it needs an internet connection. The 28 browser-first tools process locally once loaded, but the app itself requires a browser session. For pure offline editing, a desktop app may suit better.
