オンライン画像編集ツール

Convert an image into the format you need.

Open a browser-supported image, choose PNG, JPEG, or WebP, preview the result, and download a converted copy.

Conversion happens locally in your browser; your source file is not replaced.

Choose an output with confidence

PNG keeps lossless detail and transparency, JPEG is broadly compatible, and WebP is efficient for modern websites.

Can it open HEIC?

Only when the current browser can decode that HEIC file. If it cannot, export the image from Photos or use a browser with HEIC support first.

What happens to transparency in JPEG?

JPEG cannot store transparency, so transparent areas use the background color you choose.

Does conversion resize the image?

No. The converted file keeps the source pixel dimensions.
