Image Converter
Change image formats without a round trip to a server. Useful for shrinking PNG screenshots into WebP or producing JPEGs that will open anywhere.
How to use it
- Add the images you want to convert.
- Choose the output format from the dropdown.
- Press Convert and download the results.
Why it stays private
Format conversion uses your browser's own image codecs. Nothing is transmitted, so a confidential diagram or an unreleased screenshot stays exactly where it is.
Questions
Which format should I choose?
WebP is usually the best choice for the web — it is 25–35% smaller than JPEG at equivalent quality and every current browser supports it. Choose JPEG when you need maximum compatibility with older software or print pipelines. Choose PNG when you need transparency or lossless output.
Will I lose quality converting to JPEG?
Yes, JPEG is a lossy format. Each conversion re-encodes the image. If you need to convert the same file repeatedly, work from the original each time rather than from a previous JPEG.
Does converting to PNG reduce file size?
Usually not — PNG is lossless, so a PNG made from a JPEG will often be larger. PNG is the right choice for transparency and sharp-edged graphics, not for shrinking photos.
