Frequently asked questions
The most common complaints from Smallpdf users are: the 2-file-per-day free limit, surprise charges when a trial auto-starts, and OCR being behind a paywall. WhiskFile solves all three.
WhiskFile has 101 tools vs Smallpdf's ~22. WhiskFile covers everything Smallpdf does plus exclusive tools like Split by Bookmarks, Bates Numbering, E-Signature, Form Builder, Workflow Automation, and Accessibility Tools.
Yes. WhiskFile is free for up to 7 tasks per day with no account required and no credit card. No trial starts automatically.
Yes. WhiskFile Pro includes AI PDF Summarize, AI PDF Chat, and Auto-Redact PII — comparable to Smallpdf's AI features, with stronger privacy architecture (text sent to AI, not raw files).
Direct Drive/Dropbox integration is on the roadmap. Currently, download your files from those services and upload them to WhiskFile — the same steps, just manual.
Multiple user reports indicate Smallpdf's 14-day Pro trial can start without explicit opt-in, leading to unexpected charges. WhiskFile never auto-starts a trial and never requires a credit card for free usage.
No. Smallpdf OCR is locked behind the Pro plan. WhiskFile provides OCR for free to all users, with 100+ language support.
Smallpdf states most files are deleted within 1 hour, but eSign files may be retained for 14 days. Smallpdf processes files server-side on AWS (EU region). WhiskFile auto-deletes after 1 hour and processes most tools in the browser.
WhiskFile Pro includes a REST API with 38 documented endpoints. Smallpdf's API is extremely limited, with only 2 publicly documented endpoints.
Monthly price is the same ($4.99/month). Annually, WhiskFile is $39.99/year vs Smallpdf's $72/year — 45% cheaper. WhiskFile Pro also includes features Smallpdf charges extra for.
Conclusion
Smallpdf has a polished UI and large user base, but its restrictive free tier (2 merges/day), auto-trial charges, and limited API make WhiskFile the better option for users who need more free usage, transparent billing, and developer-friendly APIs. Smallpdf wins if you rely on its Google Drive/Dropbox integrations.
