Flatten PDF FAQ
How do I flatten a PDF for free?
Upload the PDF and press Flatten PDF. Form fields, annotations and overlays become part of the page - no more editing. Free, no sign-up, no watermark.
Will the text still be searchable?
This tool flattens by rendering each page as a high-quality image, so text is no longer selectable. Use this when locking the file is the goal.
Is there a page limit?
To keep it fast and free, flatten runs on up to 100 pages per file.
