Why flatten PDFs with Moriaki?
Once you’ve filled in a PDF form, flattening locks the answers in so no one can change them — useful before sending a signed or completed form. Moriaki flattens the file locally in your browser, so it is never uploaded.
The result looks identical but the fields are no longer editable — with no watermark and no sign-up.
Frequently asked questions
Is flattening a PDF free?
Yes — free, with no account, no limits, and no watermark.
Is my file uploaded?
No. Flattening happens entirely in your browser; your PDF never leaves your device.
What does flattening do?
It merges interactive form fields into the page so their content is fixed and can no longer be edited.
My PDF has no forms — can I still flatten it?
Flattening only affects interactive form fields; a PDF with no fillable fields has nothing to flatten.
Does it work on mobile?
Yes — in any modern browser, with no app needed.
