Photo Effects Online — Glitch, Dust, Bloom Free

Some photos want to be broken. A glitched album cover, a VHS-looking story frame, a scan that looks like it spent thirty years in a shoebox, a portrait with a soft white glow bleeding off the highlights. Zebra's free photo effects tool ships three of these looks — Glitch, Dust & Scratches, and Bloom — each with a single intensity slider, running entirely in your browser at full resolution. No signup, no watermark, same engine as the iOS app.

Three steps

Open the photo effects tool.
Drop in a photo and pick an effect: Glitch, Dust & Scratches, or Bloom.
Drag the intensity slider (or tap a preset — 25%, 50%, 75%, 100%) and hit Download.

Press and hold the preview to flash the original underneath; release to see the effect again. There's also a "Show original" toggle button if you'd rather click than hold.

The 3 effects — what each one actually does

Effect	What it does	The look it copies
Glitch	Splits the red and blue channels in opposite directions, shears random horizontal slices out of alignment, darkens every other row into scanlines, and sprinkles color noise	Corrupted video, VHS tracking errors, vaporwave and cyberpunk covers
Dust & Scratches	Stamps white scratches and dust marks from a set of hand-made overlay plates, randomly cropped and rotated so they never repeat	Aged film scans, celluloid that's been through a projector too many times
Bloom	A two-stage glow: an Orton-style soft lift over the whole frame, plus a bright-pass halo that makes highlights bleed white into their surroundings	Dreamy portrait glow, "soft girl" edits, vintage soap-opera lighting

A detail worth knowing about Glitch: the randomness is seeded, so dragging the slider changes the strength of the corruption, not the pattern. The slices stay where they are while you dial them in — the image doesn't reshuffle on every tick, which makes it possible to actually fine-tune a look.

Dust & Scratches gets the opposite treatment on purpose: a Randomize button re-rolls the scratch placement. Don't like where a scratch landed across a face? One click deals a new pattern at the same intensity.

What you get, in numbers

3 effects — Glitch (RGB split + slices + scanlines), Dust & Scratches (overlay-based), Bloom (two-stage glow).
0–100% intensity slider with 4 quick presets (25%, 50%, 75%, 100%).
Randomize for Dust & Scratches — re-roll the scratch pattern without touching intensity.
Hold-to-compare — press the preview to see the original, release to see the effect. Plus a click toggle.
Reset — one click back to defaults (Glitch at 50%).
Full-resolution output. PNG in → PNG out, anything else saves as JPG. No downscale.
In-browser processing — the effect is computed on a canvas on your device.
$0. Free, no signup, no watermark. Same editor family as the iOS app (1M+ downloads, 4.9 App Store rating).

Which intensity for which job

Glitch at 25–40% — "something is slightly wrong" energy. The RGB fringe is visible on edges, slices are rare. Works as a subtle style pass on posters and thumbnails.
Glitch at 60–100% — full corruption. Heavy channel smear, stacked slice displacement, obvious scanlines. Album covers, cyberpunk edits, error-core.
Dust & Scratches at 30–50% — a believable old scan. A few marks, low opacity. Pairs beautifully with a grain pass from the film grain tool.
Dust & Scratches at 70–100% — the projector-damaged look. A second overlay layer kicks in above 65%, so the wear gets denser, not just darker.
Bloom at 30–50% — a gentle lift; highlights glow softly, skin smooths out. The everyday portrait setting.
Bloom at 75–100% — full dream sequence. White halos hug every bright object.

Stacking effects

The tool applies one effect at a time, but stacking is a two-pass job: apply the first effect, download, then run the result through again with the second effect. Dust & Scratches over Glitch is the classic "damaged VHS tape" combo; Bloom over Dust & Scratches reads as an old photo shot through a soft-focus lens. And if you want color work in the chain, do it first — run a look from the photo filters tool or a darkening pass before the effect, so the effect sits on top of the final tones.

Effects vs filters vs grain — which tool do you actually want?

These get confused constantly, so here's the honest split:

Filters recolor the image — they shift tones, contrast, and color balance but don't add texture or damage. That's the filters tool, with 98 looks.
Grain adds fine, even, film-like noise across the whole frame — texture, not damage. That's the grain tool.
Effects are structural: glitch physically displaces pixels, scratches draw marks on top, bloom bleeds light. That's this tool.

A finished "aged analog" edit often uses all three, in this order: filter → grain → dust & scratches.

Common questions

How do I add a glitch effect to a photo online for free?

Open the photo effects tool, upload your photo, keep Glitch selected (it's the default), and drag the intensity slider. The effect combines an RGB channel split, displaced horizontal slices, scanlines, and color noise. Click Download to save at full resolution — free, no signup.

Does it lower the image quality?

No downscaling happens — the effect is computed at your photo's native resolution and saved at that size. PNG inputs save back as PNG; everything else saves as JPG.

Why does the glitch pattern stay the same when I move the slider?

That's deliberate. The randomness is seeded, so the slider controls strength while the pattern holds still — otherwise the image would reshuffle on every tick and you could never fine-tune it. For Dust & Scratches, where you do want a re-roll sometimes, there's a dedicated Randomize button.

Can I apply two effects to the same photo?

Yes, in two passes: apply the first effect, download, then upload the result and apply the second. Glitch followed by Dust & Scratches is the classic damaged-VHS combo.

Is the photo uploaded to a server?

The effect itself is computed in your browser on a canvas — the pixels are processed on your device at full resolution.

What's the difference between Bloom and just brightening a photo?

Brightening lifts every pixel equally. Bloom is selective: it blurs and lifts the frame Orton-style, then adds a second bright-pass layer where only the highlights survive, get pushed toward white, and bleed into neighboring pixels. Bright areas gain a visible halo; shadows mostly stay put. It reads as glow, not exposure.

Which settings make a photo look like an old VHS frame?

Glitch at 50–75%. The scanlines and the RGB fringe do most of the VHS work; the displaced slices read as tracking errors. For a "recorded off a CRT in 1994" finish, download and add a second pass of Dust & Scratches at 40%.
