使い方

  1. Choose a JPEG, PNG, or WebP image.
  2. Set the crop rectangle, rotation, scale, and optional text label, then preview the canvas.
  3. Download the edited image as a PNG.

A focused browser editor

This editor covers common quick changes without an account or upload: crop to a pixel rectangle, rotate by quarter turns or a custom angle, scale the output, and add one text annotation.

Local canvas processing

The image is decoded and rendered with the browser Canvas API. Downloaded output is PNG and does not preserve source metadata. Very large images are limited to 40 megapixels and a 10,000 pixel output side.

よくある質問

あわせて知りたいこと

Does the editor upload my image?

No. The image and every edit stay in your browser.

Can I undo an edit?

Changing any control redraws from the original image, so you can revise settings before downloading.

What format is downloaded?

The edited result is downloaded as a PNG so transparency from PNG or WebP sources can remain available.
