What this tool solves
Technical briefs often demand a 1024 px square — not 1023, not 1080. This page removes typos and preset confusion by locking width and height. Intent differs from Instagram’s 1080 square posts (`/resize-image-for-instagram`) and from passport 600×600 workflows (`/resize-image-to-600x600`).

How to use
- Upload your raster image.
- Use Cover vs Contain consciously — Cover crops, Contain pads.
- Resize, verify preview, download.
Best practices
- Start from vector or super sampled artwork when possible.
- For photos, mild sharpening after downscale can help — but avoid halos.
- Pair with compression when portals cap KB.
Common mistakes
- Confusing with Instagram’s 1080 square preset — different platform rule.
- Stretching ultrawide banners — expect distortion unless creatively intended.

Local-only processing — nothing leaves your device.
Frequently Asked Questions
Why 1024×1024 instead of 1080×1080?
1080×1080 targets Instagram feed posts. 1024×1024 is a common power-of-two friendly resolution used in game mods, asset pipelines, and icon source workflows (before downscaling). Pick the size your spec names.
Will this make my icon crisp on Retina?
A 1024×1024 master can downscale to 512, 256, and 128 cleanly. Final sharpness still depends on your original artwork — vectors or high-res sources win.
Are images uploaded?
No — local canvas processing only.
Does it output PNG?
The resize pipeline outputs JPEG for universal compatibility. Need transparency? Export PNG via design software first, then convert formats elsewhere on ImageTool.
Can I upscale a 256×256 icon to 1024×1024?
You can, but pixels are interpolated — detail will not match a native 1024 source.
Square vs circle avatars?
Export square; the destination UI masks to a circle. Keep faces centred.
