Tool Overview
Image emboss creates an embossed texture effect locally in your browser. It supports batch processing, side-by-side preview, and exports results as JPG, which is useful for posters and asset stylization.
Key Features
- Import JPG, PNG, GIF, BMP, WebP, SVG files or an entire folder
- Generate an embossed effect while keeping the original resolution
- Before/after preview, with single download and ZIP download for all results
How To Use
- Click “Choose Images/Choose Folder” or drag images into the upload area
- Click an item in the list to switch the active preview
- Use “Process Current” or “Process All” to generate results
- Download the current result, or download all results as a ZIP
Tips
- Output is always JPG; transparent areas are filled with a white background
- Some SVG files may not render to canvas (external resources or browser limits); convert to PNG first if needed
- Very large images may hit browser limits; resize before processing
Formula
The emboss effect is created by adding a constant to the difference of neighboring pixels, then converting to grayscale using: 0.30 × R + 0.59 × G + 0.11 × B.
Use Cases
- Add texture and depth to posters, covers, and social assets
- Quick stylization and batch preview for asset cleanup
FAQ
- Why is the output always JPG: for broad compatibility and faster export, with a white background for transparency
- Does embossing change the image size: no, it only changes pixel appearance without resizing
- Why can processing fail: usually due to corrupted files, SVG rendering limits, or oversized images
Privacy
All processing runs locally in your browser. No files are uploaded.
