About Image Converter

Image Converter lets you convert an image format online between JPG, PNG, and WebP in seconds, without uploading files anywhere. Use it as a JPG to PNG converter for transparency support, a PNG to WebP converter for smaller file sizes, or any other combination your project needs.

Unlike server-based converters that copy your files to a remote machine, this tool processes everything locally in your browser using the Canvas API. Your photos stay on your device and are never seen by anyone else.

Choosing the Right Format

When to use PNG

PNG keeps transparency intact, making it ideal for logos, icons, and UI graphics.

When to use JPG

JPG suits photos and complex gradients, producing smaller files at a similar visual quality.

When to use WebP

WebP supports transparency and usually lands well under both PNG and JPG at the same quality, which is why it is the default for the web.

Converting to JPG

Transparent pixels are flattened onto white, so check the preview before downloading if your source has an alpha channel.

Who Should Use This

This tool is useful for:

Developers converting photos without uploading them to prepare assets for the web.
Designers switching formats between PNG and WebP for lighter design files.
Content creators converting images to formats that platforms accept.
Businesses standardizing product photos on one format across a catalog.
Students converting screenshots and graphics for assignments and reports.

Privacy First

This tool is built on a strict privacy-first approach using a client-side architecture. Your images and chosen settings are processed entirely inside your browser. Nothing is uploaded, stored, or transmitted to a server, so your workflow stays fast, secure, and private.

You can convert between the three most common web formats: JPEG/JPG, PNG, and WebP. That covers a JPG to PNG converter, a PNG to WebP converter, and every other combination between those three formats.

Because JPG does not support transparent pixels, this image format converter automatically fills transparent areas with a solid white background before exporting. PNG and WebP output keep transparency intact.

Converting between formats uses a high quality setting by default, so visual differences are minimal for most photos. Switching from a lossless format like PNG to a lossy one like JPG can reduce quality slightly, while converting to WebP usually keeps both quality and file size favorable.

Yes, once the conversion finishes the preview gains a Source and Converted toggle so you can check the result at full size. This matters most for PNG to JPG conversions, where transparent areas become solid white.
