Image Format Converter
Convert images between JPG, PNG and WebP — instant, local, no upload queue.
About this tool
Every image format is a trade-off, and the format you have is regularly not the format you need. A form accepts only JPG; a logo needs PNG transparency; a website wants WebP for speed; a WebP screenshot won't open in older software. This converter moves images between the three formats that matter — JPG, PNG and WebP — instantly and locally, with no upload queue and no watermark.
The conversions handle the details correctly. Converting to JPEG — which doesn't support transparency — composites transparent regions onto white instead of leaving black artifacts, the classic bug of careless converters. Converting to PNG is fully lossless. Converting to WebP uses high-quality encoding that typically produces the smallest files of all three. Any browser-readable input works, including GIF and BMP.
Knowing which target to pick is half the job, so the short version: JPG for photographs going to forms, email and legacy systems; PNG for logos, screenshots, and anything needing transparency or perfectly sharp text; WebP for images destined for the web, where its smaller sizes directly improve page speed. When in doubt, convert and compare — it takes two seconds each, because nothing uploads.

Frequently asked questions
What happens to transparency when converting to JPG?
JPEG doesn't support transparency, so transparent regions are composited onto a white background — the standard, correct behavior. To keep transparency, choose PNG or WebP as the target instead.
Which format gives the smallest file?
WebP, almost always — typically 25–35% smaller than an equivalent JPEG and far smaller than PNG for photos. Every modern browser supports it; only very old software might not open it.
Is converting JPG to PNG pointless?
It doesn't improve quality (JPEG's compression loss already happened), but it's often required — many systems demand PNG uploads, and PNG re-saves without further generational loss. It's a valid conversion; just don't expect the image to look better.
Can I convert HEIC photos from an iPhone?
Only if your browser can display HEIC (Safari can; most others can't yet). If the file picker accepts it and a preview appears, the conversion will work. Otherwise, export the photo as JPEG from your phone first.
