The short answer
Why use Add Noise?
Simple overlays and markups should not require a large design application. The browser preview lets you place the element, flatten a copy, and move on.
Add Noise focuses on adding noise with control over its placement and appearance. Composition tools draw text, shapes, or additional images onto a canvas. Downloading flattens the layers, so the exported file behaves like a normal image.
The selected file stays in this browser tab and is released when you leave the page. Zoom in on text and thin lines before export. The downloaded image is flattened, so keep the source files if you may need to edit it again.
What Add Noise does
Open the source photo
Drop, choose, or paste a supported file into Add Noise. Adding noise with control over its placement and appearance. The source stays on your device; we work on a copy.
Place the extra layer
Add Noise is for adding noise with control over its placement and appearance. The preview is the place to decide if the setting went too far. The original file is not overwritten.
Useful controls
Main controls: Text, color, size, position, opacity, or layout, depending on the tool. Working limit: 50 MB and 50 megapixels per image; multi-image jobs also depend on available memory. Watch the preview at full size before you save. A current desktop browser usually has more memory than a phone.
Download a flattened copy
Export is a flattened png or a zip when the job creates several files. The download is a new file. Keep the original until you have opened the copy once.
Where Add Noise fits
These are ordinary jobs where the focused controls save time. They also show where a full editor or a manual review may still be the better choice.
Review notes
Point to a problem area with a border, arrow, label, or highlight.
Ownership marks
Add a restrained logo, timestamp, or watermark to a sharing copy.
Quick layouts
