Makes a Windows icon from a JPEG. It works, and it is worth saying that a photograph rarely makes a good icon at 16 pixels — at that size you have room for a shape, not a scene.

What survives at 16 pixels

Sixteen by sixteen is 256 pixels in total. A photograph reduced to that is a handful of coloured blobs, and it will not be recognisable as the original.

What reads at that size is a single bold shape with high contrast against the background: a letter, a simple silhouette, a distinctive outline. If the icon matters, crop hard to the one element that identifies it before converting — or draw something simple instead.

The larger entries in the icon (48, 128, 256) do keep recognisable detail, so a photographic icon can look fine on the desktop and poor in the browser tab. That is worth checking before you ship it.

No transparency to keep

A JPEG has no alpha channel, so the icon is fully opaque and square. If you want a shaped icon with transparent corners, start from a PNG.

Which sizes to put in

Windows picks the closest match from what the file contains and scales if there is nothing near, so an icon holding only a 256-pixel image looks soft in a file list and muddy in a taskbar. Including 16, 32 and 48 alongside it covers the places an icon is actually drawn small. Bear in mind what survives at 16 pixels: a photograph becomes a smear of colour, and anything that reads as an icon at that size is a simple shape with high contrast. Cropping tightly to one strong element beats shrinking the whole picture.

Questions

My icon is unrecognisable in the browser tab.
At 16 × 16 there are 256 pixels in total. Crop to the single most identifying element before converting, or use a simple graphic.
Can the icon have transparent corners?
Not from a JPEG, which has no alpha channel. Start from a PNG.
Can I convert a whole folder of images?
Yes. Drop as many files as you like, or a whole folder. Each keeps its original name with the new extension — IMG_4032.heic becomes IMG_4032.jpg, never converted_1.jpg — and you can download them individually or as a ZIP.
Are my photos uploaded?
No. The decoding and re-encoding happen in this tab using the browser’s own image support. Photos are personal in a way most files are not, and none of them is transmitted. Turn your Wi-Fi off and the converter keeps working.
