Flatten PDF for Students
It is 11:50 PM, the submission closes at midnight, and the portal rejects your 40 MB project file. If you work as one of the students, you have been there. Confileo's Flatten PDF tool merges form fields, annotations and layers into a fixed, uneditable PDF — free, in your browser, with your files deleted automatically the moment you are done.

Why flatten a PDF?
Flattening locks the final appearance so forms, stamps and notes cannot be changed or accidentally edited.
Will it still print the same?
Yes. A flattened PDF prints exactly as it appears, with everything baked into the page.
When do I need to flatten a PDF?
When sending a filled form or signed document, to lock its content and prevent fields or comments from being changed afterwards.
Does flattening lock form fields?
Yes. Fillable fields become fixed text that cannot be changed after flattening.
Does flattening fix display issues across devices?
Yes. Merging the layers makes the file display and print consistently across all readers and devices.
Can I edit the file after flattening?
No, and that is the point: a locked, final version. Keep a copy of the original if you need to edit later.
