When you fill out a PDF form or add comments, these elements exist as separate "layers" floating above the document. This means anyone can edit or remove them later.
To secure your data, you need to Flatten the PDF. This merges all layers into the background, making them permanent and uneditable.
When should you flatten a PDF?
- Invoices: Prevent clients from changing amounts.
- Contracts: Ensure terms are not modified after signing.
- Printing: Ensure complex layers print correctly without errors.
Using MYPDFTOOLS, you can flatten your documents directly in your browser without uploading them to a cloud server.
