Runs entirely in your browser - nothing is uploaded

This re-encodes an image between PNG, JPEG, and WEBP without touching its pixel dimensions. Pick a target format and the conversion runs automatically, with a live before/after file-size comparison. It's a format and compression change only. Nothing is cropped, resized, or filtered.

When you'd use this

Converting a PNG screenshot to JPEG to shrink it under an upload size limit, switching to WEBP for a smaller file at similar visual quality, or converting a WEBP file back to PNG or JPEG for a platform that doesn't accept it.

Common errors

Converting a PNG with transparent areas to JPEG doesn't keep those areas see-through. JPEG has no alpha channel, so transparency gets filled in with a solid white background during conversion. Keep it as PNG, or use WEBP, if transparency needs to survive.

This tool never changes the image's width or height. Only its format changes, plus compression quality for JPEG and WEBP. If the goal is different pixel dimensions, that's the Image Resizer, not this one.

Frequently asked questions

Does converting a transparent PNG to JPEG keep the transparency?

It can't. JPEG doesn't support an alpha channel, so any transparent pixels are filled with white before the file is saved. To keep transparency, stay on PNG or convert to WEBP instead.

Does this also resize my image?

No, the pixel dimensions are left exactly as uploaded. Only the file format and, for lossy formats, the compression quality change. Use the Image Resizer if you need different dimensions.

Why did my converted file end up larger than the original?

It depends on the source and the target. Converting a heavily compressed JPEG to a high quality setting, or to lossless PNG, can produce a bigger file than you started with. The size comparison shown in the tool reflects the actual result, not an estimate.
