Watermark & Text Overlay
Text stamp with position/opacity, tiled option.
How to use
Drop images into Watermark & Text Overlay: set Text, Position and Opacity %, press Run, and PixelFlow processes everything with a Canvas and Web Worker pipeline on your device — progress bar and cancel included. You get an instant result plus one-click download; originals are never uploaded, so DevTools Network stays clean.
Steps
- Open the tool below (or scroll to the interactive Watermark & Text Overlay).
- Set Text, Position and Opacity % images.
- Press Run (Ctrl+Enter) and watch the progress bar.
- Download the result, or copy and share the link.
FAQ
Is Watermark & Text Overlay really free?
Yes — free with no signup, no credits and no limits on this tool. It is supported by clearly labeled ads placed away from the buttons, never by paywalls.
Do I have to upload my files to use Watermark & Text Overlay?
No. Your files are read with the File API and processed with a Canvas and Web Worker pipeline on your own device — there is no upload endpoint at all. Open DevTools, go to Network, and watch: your file never leaves the tab.
What should I enter in "Text"?
Put your text here — for example: © Tolari. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.
I normally use TinyPNG — why switch?
If you are tired of upload queues, daily free limits and wondering where your photos end up, PixelFlow is the alternative: a Canvas and Worker pipeline on your device — batch plus ZIP, nothing uploaded, ever.
How accurate is Watermark & Text Overlay?
Everything runs on your device, so results are instant and repeatable — same inputs, same outputs, no server involved.
