Local processingHOW IT WORKS
A private browser workflow
Your files stay in this tab and are not sent to an image-processing server.
Choose the mark
Use text or a logo and set its scale, opacity and nine-point placement.
Render locally
Each image is decoded and composited in this browser tab without changing the source file.
Download the ZIP
Outputs are verified and bundled with collision-safe watermark filenames.
Common questions
Are originals modified?
No. The browser creates new watermarked images and never overwrites your source files.
Which logo format is best?
A transparent PNG usually produces the cleanest logo watermark.
Are files uploaded?
No. Compositing and ZIP creation happen locally in this tab.
