Preview and export 35mm borders with sprocket holes and edge markings.
Negative Converter can add a 35mm-style film border around a converted photo, including sprocket holes, frame numbers, exposed edge lettering, DX-style markings, and black film base texture.
What the sprocket border feature does
The sprocket feature adds a separate 35mm film border around the converted image. It can show top and bottom perforations, frame numbers, edge text, and DX-style markings while keeping the photo area separate from the border treatment.
This is useful for sharing a finished positive with the look of a scanned full-frame film strip, or for adding context when the original scan was cropped tightly.
Customizable border details
| Detail | What it controls |
|---|---|
| Sprocket holes | 35mm perforation preview and export with continuous pitch and offset controls |
| Frame number | Visible frame number text placed away from the photo and perforations |
| Edge lettering | Film stock style text such as brand, ISO, and roll metadata |
| DX-style code | Decorative lower edge bar markings inspired by 35mm cassette edge information |
| Overexposed sprockets | Warm exposed glow around sprocket holes while preserving the image area |
| Hole color | White, transparent, or custom hole fill depending on output needs |
Preview vs export
Use Sprocket Preview to inspect the border on the cropped and converted frame before export. Use Export Sprocket PNG when you want the final output to include the 35mm border. The normal PNG/JPEG/TIFF export remains available for clean photo-only output.
