Open the Invert Colors JPG tool, add up to 30 images, set your options below, press Convert All and download — the whole job runs on your device, so it is free, private and takes seconds.
Step by step
Load the Invert Colors JPG page. Nothing installs and nothing signs in — the editor appears immediately, ready for files.
Drag files onto the drop zone, click to browse, or paste from the clipboard. You can load up to 30 at once for a batch job.
All colour channels are inverted for a true negative. Invert a single channel (R, G or B) instead for mask and channel inspection.
Press Convert All. Because everything runs on your device, a whole queue of photos finishes in a few seconds.
Save each result individually, or grab the entire batch as a single ZIP. Files keep their original resolution unless you set a cap.
Settings that matter
| Channels | All (RGB) — a full negative. |
|---|---|
| Alpha | Transparency is left untouched. |
Pro tips & common mistakes
- Single-channel inversion is a diagnostic tool, not just an effect — use it to inspect masks and channel balance.
- Inverting a grayscale image just reverses light/dark (a solarised look).
- Batch it: up to 30 files per run beats doing them one at a time.
- Keep originals for anything critical — the tool never touches the source file, but always keep your master copy.
