Common questions
Are my files uploaded to your servers?
No. Your files are processed entirely in your browser. They are not uploaded to Filecraft servers in normal flows.
Which plan is required for Flatten PDF?
Flatten PDF requires a Pro or higher plan.
What exactly does flattening do?
Flattening converts interactive AcroForm fields — such as text inputs, checkboxes, radio buttons, and dropdowns — into static page content. The resulting PDF is no longer fillable.
Does it flatten all annotations?
No. Flattening applies to AcroForm interactive fields only. Annotations such as comments, stamps, and ink drawings that are not AcroForm fields are not affected.
What happens if the PDF has no form fields?
The operation completes without error and the output is structurally equivalent to re-saving the original.
Is there a file size limit?
On the Free plan, files can be up to 10 MB. Pro and higher plans support up to 100 MB.
