Image Converter

Convert an image between PNG, JPEG, and WebP, right in your browser.

What is Image Converter?

Image format conversion is the process of re-encoding an image from one file format to another, for example turning a PNG into a JPEG or a JPEG into a WebP. The main web image formats each have different strengths: PNG is lossless and supports transparency but produces larger files; JPEG offers strong compression for photographs but cannot store transparency; and WebP combines lossy or lossless compression with transparency support, typically at smaller sizes than either. Converting between them lets you match an image to its use case, whether that is the smallest possible download, a transparent logo background, or maximum compatibility with older software. Because the operation is lossy for some format pairs, converting repeatedly through lossy formats compounds small quality losses each time.

How to Use Image Converter

  1. Drag an image onto the drop zone, or click it to choose a file — PNG, JPEG, and WebP are all supported as input.
  2. Pick the target format (PNG, JPEG, or WebP).
  3. If converting to JPEG from an image with transparency, a note explains that the transparent areas will be filled with white.
  4. Click "Download" to save the converted file.

Examples

PNG → WebP

Input: logo.png (with transparency)

Output: logo.webp (transparency kept)

WebP → JPEG

Input: photo.webp

Output: photo.jpg (opaque background)

JPEG → PNG

Input: photo.jpg

Output: photo.png (lossless)

Common Mistakes

  • Converting a transparent PNG or WebP straight to JPEG without expecting the background to turn solid white.
  • Re-converting the same image through multiple lossy formats repeatedly (PNG → JPEG → WebP → JPEG...) — each lossy step discards a little more detail permanently; convert from the original source when possible.
  • Expecting a format conversion alone to shrink file size dramatically — for aggressive size reduction with control over the trade-off, use the Image Compressor.

Why Use This Tool

  • Converts between PNG, JPEG, and WebP entirely client-side — no upload, no server round trip.
  • Warns specifically when a conversion will flatten transparency, instead of silently producing a surprising result.
  • No file size limit beyond your own device's memory.
  • No sign-up, no watermark, no daily cap.
