Sticker Forge

How To Use

1. Add transparent PNG files by selecting multiple files or dragging them into the upload area.
2. Remove any individual file from the queue with the remove button beside that file.
3. Use the first file preview to adjust the sticker border before processing the full batch.
4. Set the border size, border color, opacity, corner smoothing, and edge sensitivity.
5. Choose whether to fill interior holes or add a smooth shape fill beneath the artwork.
6. Optional: turn on drop shadow and adjust its color, opacity, blur, and X/Y offset.
7. Select the output format and filename suffix.
8. Click Process to generate the outputs, then Download ZIP to save the processed files together in one ZIP folder.

Border And Shape Controls

• Border size controls how far the sticker edge expands beyond the visible PNG artwork.
• Border color sets the outline color. White is common for stickers, but any color can be used.
• Edge sensitivity controls how transparent pixels are treated. Lower values include more semi-transparent edge pixels.
• Fill interior holes closes transparent holes inside the design before the border is expanded.
• Shape fill creates a smoother filled silhouette underneath the sticker border.

Working With Multiple Files

The queue shows every PNG you added. Select a file in the queue to preview it with the current settings. Processing uses the same settings for the full batch, which helps keep a consistent border style across a product set.

Transparent PNGs work best. Files without transparency can still be processed, but the border will follow the rectangular image edge instead of a cutout shape.

Browser-Based Processing

Sticker Forge runs directly in your browser. Your PNG files are processed on your device and do not need to be uploaded to a server.

For large batches or very large artwork files, processing time depends on your device and browser performance.
