Fluximage applies your watermark to every image in a batch during compression. You upload one PNG file — your logo or signature — and Fluximage overlays it on all images before output, at the scale, opacity, and position you specify.

​
Setup

1

Upload your watermark file

Click Upload sig (.PNG) in the Conversion Options panel and select your watermark file. Only PNG files are accepted.
2

Set scale

Use the scale slider to control how large the watermark appears relative to each base image. The watermark is sized as a percentage of the image width.
3

Set opacity

Use the opacity slider to control how transparent the watermark is. Lower values make it more subtle; 100% makes it fully opaque.
4

Choose position

Click one of the five active positions on the placement grid to control where the watermark appears on each image.

​
Scale

The scale setting controls the watermark width as a percentage of the base image’s width.
  • Range: 5–50%
  • Default: 20%
A watermark at 20% of a 2000 px wide image will be 400 px wide. The height scales proportionally.

​
Opacity

Opacity controls how transparent the watermark is.
  • Range: 0–100%
  • Default: 80%
At 80%, the watermark is visible but lets some of the image show through beneath it. At 100%, it is fully solid.

​
Position

The placement grid has nine positions. Five are active:

TLTop-left
TRTop-right
MCCenter
BLBottom-left
BRBottom-right
The four remaining grid positions (TC, ML, MR, BC) are not available.

​
Plan requirement

Watermarking requires a Starter plan or higher. It is not available on the free plan.
Use a PNG with a transparent background for best results. A solid white or black background will show as a rectangle over your images. Most design tools (Figma, Photoshop, Illustrator) can export logos as transparent PNGs.
Watermark settings — scale, opacity, and position — apply to every image in the batch. You cannot set different watermark parameters for individual images in the same batch. If you need different watermark sizes or positions on specific images, process them in separate batches.
