Image Converter

The Image Converter changes an image between PNG, JPEG and WebP entirely in your browser. Drop in a file, pick the output format (and quality for JPEG/WebP), and download the result. Nothing is uploaded — the conversion runs locally on your device.

Different platforms want different image formats — PNG for transparency, JPEG for photos, WebP for small web images. This converter re-encodes your image to the format you need right in the browser, so the file never leaves your device.

How to use the Image Converter

  1. Drop an image in, or click to choose one from your device.
  2. Pick the output format — PNG, JPEG or WebP — and a quality for the lossy ones.
  3. Click Convert, preview the result, and download it.

Common use cases

  • Convert a PNG screenshot to a smaller JPEG or WebP for the web.
  • Turn a JPEG into a PNG when you need a lossless copy.
  • Produce a WebP version of an image to cut page weight.

Tips

  • PNG is lossless (best for graphics and transparency); JPEG and WebP are lossy (best for photos).
  • WebP usually gives the smallest file at the same visible quality — a good default for the web.

Frequently asked questions

Is my image uploaded anywhere? +

No. The conversion happens entirely in your browser using the Canvas API — your image never leaves your device and nothing is sent to a server.

Which formats can I convert between? +

PNG, JPEG and WebP. Other formats can usually be read as input, but browsers can't reliably encode AVIF from a canvas, so the output is limited to those three.

Will converting to JPEG lose quality? +

JPEG and WebP are lossy, so some quality is traded for a smaller file — use the quality slider to balance them. PNG is lossless and keeps every pixel, including transparency.
