Fill form
Forms filled in, then locked if you want.
Fillable fields are tinted so you see them. Type with Previous · Next · Done; checkboxes and dropdowns work too. On Done, choose to lock the values.

From field to field, without hunting.
A form found on opening says “This PDF has fillable fields.” The fields are tinted, and the keyboard bar jumps to the next one.

- Flatten form: fields can’t be edited later
- No fields? Mark up adds text anywhere

Questions
Is my file uploaded?
No. Fill form runs on your phone, in airplane mode too. Dokulo has no server for files.
What if the PDF has no fields?
It says “This PDF has no fillable fields.” and offers Mark up, to add text anywhere.
Does every form type work?
Most do. XFA forms can’t be filled on phones, and Dokulo says so.
Do I need Pro?
You can run it once on a real file and keep the result. After that, Pro unlocks it for good: €9.99, one-time, no subscription.
