Overview
Introduction
This tool applies a glitch-art effect to a PNG entirely in your browser, shifting rows of pixels horizontally to create a datamosh-style visual distortion.
Because the effect is driven by a seeded random generator, you can reproduce the exact same glitch pattern later just by reusing the same seed and intensity.
What Is Glitch PNG Creator?
A client-side glitch effect generator that reads an uploaded PNG's pixels and, row by row, decides (using a seeded PRNG) whether to horizontally shift that row's pixels with wraparound.
Both the decision to shift a row and how far it shifts are derived from the same deterministic random sequence, seeded by a number you choose.
How Glitch PNG Creator Works
A mulberry32 pseudo-random number generator is seeded with your chosen integer. For each row, the generator produces a value; if that value is below intensity/100, the row is selected for a shift.
The shift distance is a random amount up to a maximum derived from intensity and image width, and the row's original pixel data is rotated horizontally by that amount with wraparound so no pixels are lost.
When To Use Glitch PNG Creator
Use it to create a glitch-art or datamosh aesthetic for social graphics, album art, or experimental visuals.
It's also useful when you want a reproducible glitch effect you can regenerate later with the same seed.
Often used alongside Low Quality PNG Creator and PNG Rotator.
Features
Advantages
- Fully deterministic: the same seed and intensity always produce identical output, so results are easy to reproduce or share.
- Runs entirely client-side with no server upload.
- A single intensity value scales both how many rows glitch and how far they shift.
Limitations
- The effect is limited to horizontal row shifting; it doesn't simulate other glitch styles like color-channel splitting or block corruption.
- Very high intensity on a narrow image can make the shift amount small relative to width, since the maximum shift is capped at 30% of the image width.
Examples
Best Practices & Notes
Best Practices
- Note down the seed value you like so you can reapply the exact same glitch pattern later.
- Try several seeds at a fixed intensity to find a pattern you like, since different seeds vary the visual result a lot.
Developer Notes
The pure function uses a small self-contained mulberry32 PRNG (no external dependency) seeded by an integer, so results are fully reproducible: the same seed and intensity always generate the same sequence of per-row shift decisions and distances. Each glitched row is read into a temporary array before writing, since the shift is an in-place wraparound rotation.
Glitch PNG Creator Use Cases
- Making glitch-art social media graphics
- Adding a datamosh effect to album or game cover art
- Generating reproducible glitch variations for A/B testing visuals
Common Mistakes
- Assuming intensity alone determines the result — the seed also matters, and different seeds at the same intensity look quite different.
- Expecting vertical or diagonal glitch effects — this tool only shifts pixels horizontally within a row.
Tips
- Combine with the low-quality PNG creator for an even more degraded, chaotic composite effect.
- Use a low intensity (10-30) for a subtle glitch accent rather than a heavily distorted image.
