Image Converter
Convert an image between JPG, PNG and WebP — whichever format the thing you're using actually accepts.
Picking the right format
Each format is good at a different job. JPG is the safe default for photographs and anything you're emailing or uploading, because it's small and opens everywhere. PNG is the one to reach for when you need a transparent background or pixel-perfect sharpness on text and logos — at the cost of a bigger file. WebP is the modern option that gets you PNG-like quality at JPG-like sizes, ideal for websites, though a few older programs still can't open it.
Converting is also the quick fix when something simply refuses your file: a form that only takes JPG, or an app that chokes on WebP. Change the format and the problem usually disappears.
What conversion can and can't do
Going from a lossless format (PNG) to a lossy one (JPG) discards a little detail and flattens any transparency onto a solid background. Going the other way — JPG to PNG — won't recover detail that was already lost; you just get a larger file of the same image. So convert with the destination in mind, not out of habit.
How to convert an image to another format
- Add the image you want to convert.
- Choose the output format — JPG, PNG or WebP.

Choosing between JPG, PNG and WebP
Each format is good at a different job. JPG is built for photographs and gives small files, but it cannot store transparency. PNG is lossless and keeps transparent backgrounds and crisp edges, which makes it right for logos, icons and screenshots of text — and wrong for photos, where it balloons the file. WebP is the modern option, typically 25-35% smaller than JPG at the same quality, with transparency support, and every current browser reads it.
The one thing to remember is that converting will not restore quality already lost. Turning a heavily compressed JPG into a PNG makes a bigger file, not a better picture.

Image Converter FAQ
Which format gives the smallest file?
WebP, usually — commonly 25-35% smaller than an equivalent JPG, and it supports transparency too.
Will converting a JPG to PNG improve its quality?
No. The detail lost when the JPG was made is gone; the PNG simply stores the same picture in a larger file.
What happens to transparency when I convert to JPG?
JPG cannot store transparency, so transparent areas are filled with a solid background — usually white.
Which format should I choose?
JPG for photos and general sharing, PNG for transparency or crisp text and logos, WebP for the web when you want small files at good quality.
Will converting to JPG remove the transparency?
Yes. JPG has no transparency, so any transparent areas are filled with a solid background. Keep it as PNG or WebP if you need the transparency.
Is anything uploaded during conversion?
No. The image is converted in your browser and never sent to a server.
