Convert JPG to PNG to WebP online — free, no quality surprise
Need a PNG but you only have a JPG? Or a smaller WebP for a web page? The Image Converter switches formats in your browser. No upload, no install — drop the file, pick the target, download.
Which format when
JPG is for photos: small files, loses a little detail (lossy), no transparency. PNG is for graphics, screenshots and anything with text or sharp edges: lossless, supports transparency, larger. WebP is the modern middle ground — smaller than JPG or PNG at similar quality, and it supports transparency too. If you're shipping images to a website, WebP usually wins on size.
The trap: transparency and re-compression
Converting JPG to PNG does NOT magically add transparency — JPG has none, so you'll get a solid background. Converting PNG to JPG DOES drop transparency, replacing it with white (or black). Know which way you're going.
Also: converting JPG to JPG (re-saving) loses a little more each time. If you must re-export, prefer keeping an original or exporting to PNG to stop the quality bleed.
How the converter works here
Drop the source, choose the output format, and download. It's a local Canvas transform, so the bytes never leave your machine. For batch needs, convert one at a time — the tool is built for privacy, not bulk server processing.
Frequently asked questions
Does converting JPG to PNG improve quality?
No. PNG is lossless, but it can only preserve what the source already has. A JPG's lost detail stays lost; PNG just stops further degradation.
What happens to transparency when I convert PNG to JPG?
JPG has no transparency, so transparent areas are filled with a solid color (usually white). Use PNG or WebP if you need to keep transparency.
Is WebP safe to use everywhere?
WebP is supported by all current browsers and most modern tools. Very old software may not open it, so keep a PNG/JPG original if you support legacy systems.
Is the converter private?
Yes. Conversion runs in your browser; the image is never uploaded.
