QR Code Background (1080)

1080×1080 PNG · for poster overlay

Design assets often have to ship at a single canonical size — an icon set, a profile picture, a thumbnail — because platforms or frameworks will reject anything off-spec. QR Code Background (1080) produces 1080×1080 PNG, the size QR Code Background (1080) expects.

When you'd run QR Code Background (1080)

Replacing a generic placeholder with a hand-crafted asset at the correct 1080×1080 pixel size.
Sizing brand assets for client deliverables, design portfolios, or system-mockup exports.
Preparing assets for a CMS or template that requires a specific pixel dimension.
Generating consistent thumbnails or hero images across a content series.

About QR code render contexts and this preset

Audience: any printed or digital QR scan target.

How QR code render contexts ranks images: QR readers tolerate light perspective skew but quiet-zone (white border) is mandatory. Posting at the platform's exact native dimensions (1080×1080 px) preserves your original framing and avoids the softening that happens when the platform's own resampler runs to fit its expected size.

Platform-specific note: QR codes need a 4-module-wide quiet zone around the code itself; cropping the quiet zone is the most common reason QR scans fail.

How QR Code Background (1080) runs

This preset is a deterministic recipe — every step has fixed parameters so the result is byte-identical across runs of the same input.

Crop the image to a 1:1 aspect ratio. Mochi keeps the centre of the frame in the middle of the crop by default — drag the crop box if you want to recompose.
Resize to 1080×1080 px as PNG.

Where the work happens

QR Code Background (1080) crops your input to 1:1 and resizes it to 1080×1080 px as PNG — a 1.2-megapixel output. The work runs through canvas APIs and a WebAssembly image-encoder; the source image is decoded into an off-screen canvas, transformed in place, and re-encoded without any network upload.

Design deliverables to clients often require an exact pixel-size; this preset's deterministic output makes the deliverable repeatable. The browser-side path also means the file never leaves your device — relevant when the input contains personally identifiable information, screenshots of private documents, ID scans, or proprietary product photography.

Common mistakes

Generating only the 1080×1080 version when the platform also needs a 2× retina variant. Check whether you need a 2160×2160 export for HiDPI screens.
Submitting a JPEG when a transparent background is required. This preset outputs PNG to preserve transparency where the platform expects it.
Burning anti-aliased edges into a coloured background. Render your source on transparent first, then run this preset, so the icon edges blend cleanly on whatever surface it lands on.
Uploading sensitive images to a server-side tool. This preset runs entirely in your browser; the file never leaves your device. Verify this in your browser's network panel if working with confidential material.

FAQ

What does QR Code Background (1080) output?

1080×1080 px, saved as PNG.

Why is the output square (1:1)?

The design this preset targets uses 1:1 framing. For passport photos this matches the printed-photo standard; for social posts it's the safe ratio that fills the feed without horizontal cropping.

Why PNG and not JPEG?

PNG preserves hard edges and transparency that JPEG would smear. Icons, logos, and screenshots compress better as PNG when the image isn't photographic.

Does my image get uploaded?

No. This preset runs entirely in your browser using WebAssembly + canvas APIs — no server round-trip. You can verify this in your browser's network panel: only static asset requests, no image upload. The file never leaves your device.
