How to use it
- Choose an existing PDF or explicitly start a blank A4 or Letter page.
- Add a field, choose its type and assign a unique name and visible label/tooltip.
- Set page, position, dimensions, font and text alignment. For radio and list fields, enter one option per line and choose an optional initial value.
- Set required/read-only flags. Duplicate or remove fields, reorder their creation and use undo/redo to correct the design.
- Create the fillable PDF and review the actual output preview. Open it in a PDF reader, enter answers, save and reopen to confirm the result.
Start on blank A4. Create a required name field, a multiline note, a checkbox, an Alpha/Beta radio group and a country dropdown. Their names must be distinct and their initial selections visible after reopening.
Details & limits
Local PDF processing: 25 MiB, 100 pages, 200 fields/additions and 4,000 characters per field; 60 seconds per operation. Encrypted, digitally signed, XFA and scripted PDFs or embedded files are rejected. Embedded images support checked JPEG and unfiltered/Flate pixels, up to 8,192 px per side; no inline images, JPEG 2000, JBIG2 or CCITT. Large expanded resources can be rejected. Existing fields remain unchanged; the total limit is 200 fields and 500 widgets. New field names use letters, digits, underscore and hyphen, starting with a letter. Labels and initial text use Western European characters. Field order supports annotation-order navigation; PDF reader preferences may override tab behavior. Dates can be clearly labeled text fields, without a promised calendar popup.
Are these actual fields, and is automatic field detection required?
The output contains real AcroForm fields and saved appearances. This version uses explicit manual authoring, without claiming automatic detection. Existing fields are preserved. No validation/calculation scripts are inserted; navigation and some appearance details depend on the PDF reader.
