How to glitch a photo online

  1. Drop a photo onto the canvas, paste it, or click to choose one. It never leaves your browser.
  2. Pick a filter — CRT Scanlines, Pixel Sort, Pixel Sort V, Signal Mix, Pixel Crush or Chroma Pop — then move Detail to set how fine or coarse the damage is.
  3. Export the PNG. No account, no watermark.

How the glitch effects work

Digital glitch art is the intentional corruption of data structures that were meant to stay invisible. A camera sensor records a rigid grid of pixels, an encoder serialises them into rows, and a screen paints them line by line. Glitch algorithms break those assumptions along three distinct fault lines:

  1. Signal-Level Destruction (CRT Scanlines & Phase Shifts): The CRT filter simulates the optical behavior of cathode-ray tube displays. It inserts dark raster scanlines between pixel rows and offsets the sub-pixel color phases. Bright areas bloom across raster boundaries, reproducing the phosphorescent bleed of analog video monitors.
  2. Sequence-Level Destruction (Pixel Sorting): The Pixel Sort and Pixel Sort V filters scan along rows or columns, measuring luminance against a threshold. Contiguous runs of pixels that cross the threshold are sorted dark-to-bright in-place, turning structural silhouettes into smeared liquid trails while leaving calm regions intact.
  3. Quantisation & Decimation (Signal Mix, Pixel Crush & Chroma Pop): All three resample the photo into a coarse grid. Signal Mix redraws each cell as a character from a mixed ramp (@ ▓ # + · : -) with a little random jitter, like corrupted teletext. Pixel Crush averages each cell and posterises every colour channel to 5 levels, like a low-res console signal. Chroma Pop* turns each cell into a glowing neon dot sized by its darkness.

> Frequently Asked

What is an online glitch generator?
A glitch generator is a tool that deliberately corrupts or distorts the mathematical structure of an image — introducing CRT television scanlines, phosphor bloom, sorting pixel sequences, or quantising color channels — to produce cyberpunk and retro-digital aesthetics.
How does this glitch generator differ from pixel sorting?
Pixel sorting is one specific glitch operator that reorders pixels along rows or columns by luminance. A complete glitch generator combines multiple destruction mechanisms: signal raster emulation (CRT), sequence displacement (Pixel Sort), and coordinate quantization (Signal Mix and Pixel Crush).
Is the glitch generator free and private?
Yes. It operates 100% client-side inside your browser through the Canvas 2D API. Your photos never leave your device, no account is required, and PNG exports (up to a 1400px long edge) carry zero watermarks.
Can I create animated glitch GIFs or videos with this tool?
This browser generator exports high-resolution static PNGs. If you need live real-time camera processing or continuous video distortion, check out the Yan mobile app on iOS and Android.
Which photos produce the strongest glitch effects?
High-contrast images with defined light sources, neon signs, typography, or sharp silhouettes produce the most dramatic results. CRT bloom clings to highlights, while pixel sorting needs distinct luminance boundaries to create crisp streaks.
