What is a PNG converter?
PNG is a lossless format: it stores every pixel exactly as it was created. That is excellent for logos, graphics and screenshots, and it is why the files tend to be large — especially for photographs, where there are millions of colours and little repetition for the format to exploit.
A converter swaps that format for one better suited to its destination. On the web, where page weight directly affects loading time, turning a 2.8 MB PNG into a 300 KB WebP is the difference between a page that opens and one the reader abandons.
PNG to JPG
JPEG uses lossy compression: it discards information the human eye is unlikely to notice. It is the best choice for photographs, where that loss is practically invisible and the saving is substantial.
The important limitation is transparency: JPEG has no alpha channel. When converting a transparent PNG, the empty areas need a colour — which is why this tool asks which one before converting, instead of deciding for you.
It is also the most compatible format: there is no relevant browser, system or program that cannot open a JPEG.
PNG to WebP
WebP was designed for the web and usually produces smaller files than JPEG at the same perceived quality. Unlike JPEG, it preserves transparency — which makes it the most direct replacement for PNG in logos, icons and cut-out images.
Support is broad: every current browser displays WebP. For most websites, it is the safest default.
PNG to AVIF
AVIF is the newest of the three and usually compresses best: at the same perceived quality it produces smaller files than WebP and considerably smaller than JPEG. It also preserves transparency and handles gradients well, where older formats show banding.
The trade-off is slower encoding — it is the only one of the three that no browser encodes natively, and here it runs through WebAssembly inside the page itself. A large image may take a few seconds.
Which format should you choose?
| Format | Best for |
|---|---|
| PNG | Graphics, logos and transparency, when nothing can be lost. |
| JPEG | Photographs and broad compatibility. |
| WebP | General website use: a good balance of size, quality and support. |
| AVIF | The best compression available, when conversion time is not a concern. |
Frequently asked questions
Does converting PNG to JPG reduce quality?
Yes, JPEG uses lossy compression. But at high quality levels — 90 to 95, which is this tool default range — the visual difference is practically imperceptible on most images, while the file gets considerably smaller. On images with fine text or high-contrast lines the loss shows up sooner; there, WebP or PNG are usually the better choice.
Which JPEG quality should I use?
For images destined for the web, somewhere between 90 and 95 is usually the best balance. Below 70, visible blocking starts to appear in gradients and skin tones. Above 95 the file grows quickly without a proportional visual gain.
Is WebP better than JPG?
It depends on the goal. For most website use, WebP delivers smaller files at equivalent quality and preserves transparency as well. JPEG still wins on compatibility with older programs and devices, and it is the format anyone can open without thinking about it.
Is AVIF better than WebP?
On compression, usually yes: at the same perceived quality, AVIF tends to produce smaller files. But it is not superior in every respect. Encoding is considerably slower, support in editing tools and older systems is still narrower, and on small images the size advantage nearly disappears. For a modern site, AVIF with WebP as a fallback is a solid combination.
Are my images uploaded to a server?
No. Conversion happens entirely inside your browser, using your own device resources. No file is sent to our servers, to third-party services or to any storage. Nothing is kept after you close the page, and you can verify it by disconnecting from the internet: the converter keeps working.
