Making a game?

Nerulio is a 2D game asset studio first: draw pixel art, cut sprite sheets into animations, pack texture atlases, check autotile tilesets and export them for Godot, Unity, Phaser and other engines. It runs in your browser; files stay on your device.

Crop image

Drag on the image or choose an aspect ratio.

How it works

  1. Drop an image
  2. The crop box is already placed: drag it, or pick an aspect ratio or platform size
  3. Check the result size and download

Supported formats

PNG / JPG / WebP / AVIF / HEIC → PNG / JPG / WebP — Input decoding and output encoding depend on browser support. Animated inputs are rejected; select a still frame first.

What this tool does

Frames an exact pixel rectangle, with 90° turns, mirroring, straightening, a circle or rounded shape and an optional exact output size.

Implementation and verified quality

basic · Canvas region copy. Quality qualification is in progress. Pro/Flagship quality has not been established.

Before you export

Cropping reduces dimensions and cannot reveal content outside the original image. Straightening and scaling to an exact size resample the picture.

Frequently asked questions

Can I crop several images the same way?

Yes. Drop them all and use "Apply this crop to all"; every file keeps its own box and they can be saved together as a ZIP.

Are my files uploaded?

Nerulio processes selected files on your device and has no file-upload API. Optional engines and models are downloaded from third parties; those requests expose connection information such as your IP address.

Will my work be saved automatically?

No. Images and editing state stay in this tab; media output can use local temporary storage. Changing language preserves your work; reloading, closing the tab, or following a link to another page can clear it.
