Sejda is a very capable tool with a good editor; fair is fair. This comparison contrasts, with facts verifiable as of July 11, 2026, how each free plan works and what each offers.
| Sejda | AIM PAPYR | |
|---|---|---|
| Free plan model | Limited by tasks and per hour; short paid passes | Classic tools always free, no daily task limit |
| Ads | No ads | No ads. Ever. |
| Your files | Processed on their servers (per their policy) | Discarded on response: zero retention |
| AI over the document | Not its focus | Chat with several PDFs with citations, an agent that proposes and runs on your approval, summaries — with a free daily allowance |
| Facturae / Spanish tax IDs / payslips | Doesn't exist | Validate Facturae 3.2.2, NIF/CIF/NIE, payslips to Excel |
| Verify whether a PDF was altered | Doesn't exist | Yes: local cryptographic verification + public QR seal |
| Video & audio | None | Convert, compress, trim, subtitles, MP3, GIF — free |
| Active privacy | Not its focus | PDF X-ray, one-click anonymisation, EXIF report, safety check |
Yes: every classic tool is free, ad-free, CAPTCHA-free, card-free and account-free. AI features include a free daily allowance.
What Sejda does well: a polished, direct PDF editor, and a short-pass model that suits some people for one-off use. If that's exactly what you want, it's a solid choice. We say it plainly.
