  • How it works

    Okaysize finds every field in the form, the text boxes, check boxes, radio buttons, dropdowns, and signature boxes, and puts an input right where it sits on the page. Type your answers, then save. Each answer is written into the PDF and drawn into its field, so it shows in other PDF readers and when you print.

  • Government and tax forms

    Many official forms carry a second, hidden copy of the form (called XFA) that some readers show instead of the fields. Okaysize removes that copy when it saves, so every reader shows the same answers you typed.

  • Keep it fillable or lock it

    By default the saved PDF is still a form, so you or someone else can change an answer later. Turn on Flatten after filling to make the answers part of the page before you send it.

Questions

My PDF has no fields to click

Then it isn't a fillable form, just a picture of one. Use Edit PDF to type anywhere on the page instead, or Create PDF form to add fields to it.

Is my form uploaded?

No. The form is read and filled in on your device. Your answers aren't kept in the browser either.

Can I sign the form?

Yes. Click Sign here in a signature box, then draw, type, or upload your signature. It's placed in the box as a picture of your signature, which is what most forms ask for. It isn't a certificate based digital signature.

Can I type in Hindi or other scripts?

Yes, the answer is saved in the form. The standard PDF font only draws Latin letters, so readers like Adobe Reader and Chrome draw other scripts themselves. If you flatten the form, use Latin letters.

The form says it needs Adobe Reader

Some forms are built only for Adobe's own format (XFA) and have no normal fields. Okaysize tells you when that's the case. Open those in Adobe Reader.

My PDF is password protected

If it asks for a password to open, unlock it first with Unlock PDF, then fill it in.
