Frequently asked questions

How do I convert PNG to JPG?+

Add your PNG files, choose JPG and click Convert. Transparent areas are filled with the background colour you pick (white by default), because JPG can't store transparency.

Should I use JPG, PNG or WebP?+

Use JPG for photos, PNG for screenshots, logos and images that need transparency, and WebP for websites, since it makes files smaller than both while keeping good quality.

Can I convert HEIC photos from an iPhone?+

Only if your browser can open HEIC files, which most can't (Safari on a Mac can). On an iPhone you can set the camera to "Most Compatible" to save photos as JPG instead.

Is converting images here private?+

Yes. The conversion uses your browser's built-in image tools, so nothing is uploaded and the files stay on your device.
