Frequently Asked Questions

Which image formats does the converter support?

You can convert between PNG, JPG / JPEG, and WebP in any direction. Just upload an image in one format and pick the format you want to download.

Does converting between formats lose quality?

Going from JPG or WebP to PNG is lossless — the PNG will be identical to the visible pixels of your source. Going to JPG or WebP uses lossy compression (adjustable via the quality slider), which is why JPG and WebP files are smaller but discard a tiny amount of detail.

Why would I convert PNG to WebP?

WebP files are typically 25–35% smaller than the equivalent PNG with identical visual quality. If your website targets modern browsers, serving WebP instead of PNG dramatically speeds up page loads and improves Core Web Vitals.

Is this image converter private?

Yes. The entire conversion runs client-side in your browser using Canvas. Your images never touch our servers, nothing is logged, and nothing is stored after you close the tab.

Can I convert transparent PNGs to JPG?

JPG does not support transparency, so transparent areas will be filled with a background colour (white by default) during conversion. If you need to keep transparency, convert to PNG or WebP instead.

Is the Image Format Converter free?

Yes — free, unlimited, no signup, no watermark, and runs entirely in your browser.
