Image Converter
This free image converter tool takes any image you drop, paste or browse to and re-encodes it as PNG, JPEG, WebP, AVIF, GIF, an ICO favicon, or an SVG wrapper. All conversion happens on your device, so your images never leave your browser.
How to use Image Converter
- 1 Drop an image, click to browse, or paste one with ⌘V / Ctrl+V.
- 2 Pick an output format: PNG, JPEG, WebP, AVIF (where supported), GIF, ICO, or SVG.
- 3 For lossy formats, drag the Quality slider to balance size against sharpness.
- 4 Click Convert, then download the result — your image is never uploaded.
Frequently asked questions
Are my images uploaded to a server?
No. Every conversion happens locally in your browser using the canvas and built-in encoders, so your images stay on your device.
Which formats can I convert to?
PNG, JPEG, WebP, GIF, a multi-size ICO favicon (16, 32 and 48px), and SVG that embeds the image. AVIF is also offered when your browser can encode it.
What does the quality slider do?
For lossy formats like JPEG, WebP and AVIF it sets compression from 10% to 100% — lower makes smaller files, higher keeps more detail. PNG is lossless and ignores it.
Does the converter work offline?
Yes. PDFPowerHub is a PWA, so once loaded it keeps converting images with no internet connection.
