After annotating, click save in the top left. All changes will be irreversibly solidified into a standard PDF and downloaded.

Online PDF Editing FAQ
Due to security and browser native architecture limits, we currently offer 'incremental editing' (whiteout, add text, brush, highlight). You can cover the typo with a white box and type new text over it, which visually looks perfect.
Absolutely. All our editing operations strictly follow PDF ISO standards for serialized saving. Once exported, your annotations will be clearly visible no matter what device or reader they use.
To prioritize pure local processing speed, a real-time persistence mechanism is not yet introduced. If you accidentally close the page, the current progress is lost. We strongly recommend clicking 'Save & Export' periodically as a backup during heavy annotation.
