When you'd run Profile Picture (square)

Replacing a generic placeholder with a hand-crafted asset at the correct 1024×1024 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.

How Profile Picture (square) 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 1024×1024 px as PNG.

Where the work happens

Profile Picture (square) crops your input to 1:1 and resizes it to 1024×1024 px as PNG — a 1.0-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 1024×1024 version when the platform also needs a 2× retina variant. Check whether you need a 2048×2048 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 Profile Picture (square) output?

1024×1024 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.
