Image Format Converter (PNG / JPG / WebP)

How to Use

Drag an image into the drop zone (or click to choose), pick an output format (PNG / JPG / WebP), and the browser produces the converted file. For JPG and WebP, quality (0–100) is configurable. The converted image's size and dimensions are shown alongside a download button.

Format Trade-offs

PNG is lossless and supports transparency — good for logos and icons. JPG is lossy and lacks transparency — good for photos. WebP is a modern, efficient format supported across all major browsers and replaces both PNG and JPG well. The tool uses the Canvas API, so any image format the browser can decode (GIF, BMP, etc.) can be read in and re-encoded into one of the three target formats.

Use Cases

  • Compressing screenshots (PNG) into WebP / JPG for the web
  • Optimizing phone photos (after iOS HEIC export to PNG/JPG) to WebP
  • Falling back from WebP to PNG/JPG for legacy systems
  • Converting transparent PNG logos to JPG (with white background) for social media
  • Reducing site image weight by switching to JPG / WebP

Privacy

Conversion happens entirely in the browser via Canvas; images are never uploaded. Internal documents or images with personal data stay local.
