Negative Image Restorer runs entirely in your browser to convert negative-looking images back to normal-looking colors. It supports batch processing and downloads for film scan cleanup, retouching checks, and design asset correction.
Main Features
- Upload JPG, PNG, GIF, BMP, WebP, SVG, or import folders in batch
- Restore negative-looking colors with RGB channel inversion while preserving image resolution
- Side-by-side source/result preview with per-image and batch downloads
How to Use
- Click "Choose Images" or drag files into the upload area
- Select an item in the list to preview
- Click "Convert Current" or use "Batch Convert" for all images
- Download the current result or download all generated results
Restore Rule
For each pixel channel R/G/B: new = 255 - old.
Notes
- This tool follows the local restore-color logic and only inverts RGB channels
- Resolution is preserved, while output is unified as JPG
- All processing happens locally in your browser without server upload
FAQ
- The core rule is the same as invert tools, but this page is organized for negative restoration workflow
- If a file cannot be read, check whether it is corrupted or unsupported
- Batch download only includes images that already have generated results
