Before you start: Confirm these points first

Taking a few minutes to confirm the following items before taking action can save you a lot of detours.

Confirm file type. Click in the blank input box to see if the input cursor appears. Only form fields can be used to enter text; if there is no response after clicking, it means it is a flat file. You can also try to select a piece of text with the mouse. If you cannot select it, consider that it is a scanned image.
Confirm template version. The other party may have updated the form, and the old version of the fields does not match the new requirements. Before submitting, ask if it is a new version to avoid filling out the form only to find out that you have to start over.
Prepare all information. The ID number, date, address, amount, etc. are prepared in advance and filled in against the originals. Repeated revisions increase the chance of errors.
Get the software ready. Download the desktop client at download.omnidoc.top, supports Windows, macOS and Linux.
Copy the original file first. Once the original template is overwritten, it is difficult to restore a blank version. Make a copy of it and fill in the copy.

❓ Frequently Asked Questions (FAQ)

uncertain. Most of the time it is a flat file with no form fields on the page. You can select a piece of text first. If you cannot select it, it means that it may be a scanned image, and you need to do OCR recognition first.

2. Can the form content be modified after filling it out?
