Can I place the watermark in the center or a corner?
Yes. Choose the center or any of the four corners. The editor keeps a margin between the text and the image edge.
Can I change watermark opacity and color?
Yes. Adjust opacity from subtle to fully visible, choose a text color, and resize the mark relative to the image.
Does this tool remove or prevent copying?
No watermark can prevent every copy or crop. It adds visible attribution or status text; keep original files and use appropriate rights-management practices for valuable work.
Does Instasize upload my image to process this effect?
No. This editor decodes, renders, and encodes the image in your current browser tab. The file only leaves your device if you choose a separate upload or sharing action afterward.
What file will I download?
The current browser editor exports a PNG. PNG keeps the result predictable across supported browsers and preserves transparent corners when the effect creates them.
