GlitchaRGB Split Generator
Slide the red, green and blue channels apart along an axis — the classic mis-registered-print look, live and adjustable. Nothing gets uploaded; it's just canvas math running in your tab.

How RGB splitting actually works
Every digital photo is really three grayscale images stacked on top of each other — one red, one green, one blue — lined up pixel-for-pixel. This tool takes that stack apart and slides each layer a few pixels in a different direction before putting them back together. Where they no longer line up, you get color fringing: the same edge painted three times, slightly out of register.
It's the same physical phenomenon as chromatic aberration in a cheap camera lens, or the color bleed you'd get from a slightly misaligned printing press — we're just doing it on purpose, and exaggerating it until it reads as an effect instead of a defect. The amount controls how far apart the channels drift; the direction controls the axis they drift along.
A few things worth trying
- Small offsets (a handful of pixels) read as a lens artifact — good for a subtle, almost-real look.
- Large offsets turn edges into full color bands — good for posters, album art, anything meant to pop.
- Horizontal splits read as tape or scan-line damage; diagonal splits read more like a print misregistration.
- High-contrast images (text, logos, hard silhouettes) show the effect far more clearly than soft, low-contrast photos.
Questions
- Is this really free?
- Completely. It runs on the same effect engine as the full editor, right here in your browser — no trial, no watermark, no catch.
- Is my photo being sent to a server?
- No. Everything from decoding to export happens locally on your device — there's nothing to send.
- Can I animate the RGB split, or add more effects?
- Yes — send it to the full editor to stack on more effects, mask off specific regions, or animate the split into a GIF, WebM or MP4.
