Does the form work in Acrobat and other readers?
Yes: it is a standard PDF form (AcroForm), with real fields any PDF reader can fill in, in the page's reading order.
Which fields can be added?
Text fields (on one or several lines), check boxes, drop-down lists, groups of radio buttons and signature fields, each of which can be made required.
Is the automatic detection reliable?
It finds lines of underscores or dots and boxes (☐ or small drawn squares), and names each field after the text beside it; check the result, every field can be corrected or deleted.
Are my files sent to a server?
No. Everything is processed in your browser, on your device: no file is sent anywhere, neither to ElniDocs nor to anyone else. You can check this by going offline once the page has loaded: the tool keeps working.
Is it free? Do I need an account?
It is free, with no sign-up, no adverts and no watermark added to your files. The only limit is your device's memory (up to 500 MB per file).
