or click to browse your files

Supports PNG, JPEG, WebP, and GIF

How to Use

  1. Upload an image — Drag and drop a PNG, JPEG, WebP, or GIF file onto the upload area, or click to browse your device. The original preview, dimensions, file size, and type appear instantly.
  2. Choose the target format — Select PNG, JPEG, or WebP from the dropdown. When JPEG or WebP is selected, adjust the quality slider to balance file size against visual fidelity.
  3. Convert — Click the convert button. The image is re-encoded locally in your browser via the Canvas API—nothing is uploaded anywhere.
  4. Download — Review the converted preview and its new file size, then click download to save the file with a matching extension.

Frequently Asked Questions

Are my images uploaded to a server?

No. All conversion happens entirely in your browser using the Canvas API. Your images never leave your device, which makes the tool private, fast, and usable offline once the page has loaded.

What happens to animated GIFs?

The Canvas API can only decode the first frame of an animated GIF, so converting a GIF produces a still image of its first frame. Use this tool for static images, or when you only need a poster frame of an animation.

What does the quality slider do?

For JPEG and WebP output, the slider controls lossy compression from 10% (smallest file) to 100% (best quality). PNG is lossless, so the quality option is hidden when PNG is selected as the target format.
