Flatten PDF
Fix supported PDF form appearances.
Create a copy that turns supported interactive form-field appearances into fixed page content.
Private by design
Ordinary document processing happens in browser memory. The document is not intentionally uploaded to our application server, so there is no server copy of the file to delete.
No account required
Choose a supported file, complete the task, download the result, and keep control of the original.
How to use it
- 1Choose Flatten and select a filled PDF.
- 2Copy supported field appearances into the pages locally.
- 3Download and inspect every field in the fixed copy.
What it does well
- Useful before sharing a completed form copy.
- Runs locally in browser memory.
- Preserves the interactive original.
Important limitations
- Unsupported widgets or scripts may not survive.
- Flattening does not validate field accuracy.
- Always retain the original form.
Frequently asked questions
Is the document uploaded?
No. This ordinary tool is designed to process the selected file in browser memory and does not intentionally send document content to our application server.
Can recipients edit flattened fields?
Supported appearances become page content, but this is not tamper-proof document security.
