JPG, PNG and WebP — what's the difference?
These three formats cover almost every image on the web, and each is built for a different job. Converting between them is really just re-encoding the same pixels using a different compression scheme. This tool does that on a hidden canvas inside your browser, so your files are converted instantly and never leave your device.
When to use JPG
JPG (also written JPEG) uses lossy compression tuned for photographs and other images with smooth colour gradients. It produces small files and is supported everywhere, which makes it the default choice for photos on websites, email and social media. Its limitation: it has no transparency, and repeatedly re-saving a JPG slowly degrades quality.
When to use PNG
PNGis lossless and supports full transparency, so it's perfect for logos, icons, screenshots, and any graphic with sharp edges or flat colour. Text and lines stay crisp with no artefacts. The trade-off is file size: PNG photos are much larger than the JPG or WebP equivalent, so reserve PNG for graphics rather than photographs.
When to use WebP
WebP is the modern all-rounder. It supports both lossy and lossless compression andtransparency, and it typically produces files 25–35% smaller than JPG or PNG at comparable quality. It's supported by every current browser, so WebP is usually the best choice for images you serve on a website. Keep JPG or PNG on hand for older software or platforms that still expect them.
Frequently asked questions
Are my images uploaded anywhere?+
No. The converter runs entirely in your browser using the HTML Canvas API. Your images are processed locally and never uploaded, so they stay completely private.
Which formats can I convert between?+
You can convert freely between JPG, PNG and WebP. Upload any of the three and export to any of the three — including mixed batches of multiple images at once.
What happens to transparency when I convert to JPG?+
JPG does not support transparency, so any transparent areas are filled with white before export. If you need to keep transparency, choose PNG or WebP instead.
Which format should I choose?+
Use JPG for photos where small size matters, PNG for logos, icons and screenshots that need transparency or crisp edges, and WebP when you want the best of both — small files with transparency support.
Does converting reduce image quality?+
Converting to PNG is lossless. Converting to JPG or WebP re-encodes at high quality (about 92%), which is visually near-identical for most images while keeping files small.
Can I convert several images at once?+
Yes. Drop or select multiple images, pick your output format, and download them individually or all at once with the Download all button.
