JPG to ICO converter for photo icons
Convert a JPG to ICO when a photo or a scanned logo has to become a favicon or a Windows icon. ToolHero puts up to four sizes in one file: 16, 32, 48 and 256 px. The picture stays opaque, as JPGs are, and a photo that isn’t square is padded with transparency, never cropped.
From a photo to 16 pixels
A JPG is usually a photo, and a photo holds far more detail than an icon can show. At 256 and 48 px a face or a close-up still reads well; at 16 px a whole landscape turns into a few blocks of colour. Pick a picture with one clear subject and strong contrast.
Our 12 MP test photo shows the scale of it: 3024×4032 pixels become a 256 px icon at most, so 5.2 MB of JPG turns into 117 KB, most of it the 256 px picture. Its Display P3 colours are converted to sRGB on the way, because an icon carries no colour profile.
Square it, or let it be padded
Icons are square and photos rarely are. ToolHero never crops: a portrait is centred with clear strips left and right, a landscape with strips above and below, so nothing of the picture is cut off.
To fill the whole square instead, open the photo in Crop, pick 1:1 and then convert. Your files stay in the workspace when you switch tools, and the icon is still made in one pass from the original JPG.
The photo itself stays opaque. JPG has no transparency to carry over, so a white background stays white. For a cut-out icon, start from a PNG with a transparent background: PNG to ICO keeps it.
Where ICO files are still used
Windows keeps icons for programs, shortcuts and folders in ICO files, and for each view it picks the closest of an icon’s sizes, scaling it when none matches. That is why one file holds several.
On the web, a favicon.ico in a site’s top folder is the oldest favicon there is, and Google Search accepts ICO among its favicon formats. Phones are the exception: iPhones and iPads look for a 180 px PNG touch icon instead.
Why convert JPG to ICO?
How it works
-
Step 1:Add a JPG
A photo or a logo both work. Square pictures fill the icon; crop others to 1:1 first if you don’t want clear strips.
-
Step 2:Press Convert
ICO is selected already and there’s nothing to set. Each item then lists the sizes its icon holds.
-
Step 3:Download the .ico
Use it as a favicon, or choose it under Change Icon in a Windows shortcut’s properties.
JPG vs ICO at a glance
How the two formats compare, so you know what to expect.
JPG
Your filesThe classic photo format. Every phone, computer, app and website has opened JPGs for decades.
Best for Photos you want to share anywhere: email, chat, print services and older software.
ICO
What you getA small file of square pictures at several sizes, so Windows and browsers can show the sharpest one wherever the icon appears.
Best for Website favicons, and the icons of Windows programs and shortcuts.

Questions, answered
Can a photo make a good icon?
At 48 and 256 px, yes. At 16 px a busy scene turns to mush, so a close-up, a face or a logo on a plain background reads much better.
Why does my icon have clear strips on two sides?
Icons are square and most photos aren’t. Rather than cut your photo, ToolHero fits it inside the square and leaves the rest transparent. Crop to 1:1 first to fill it.
Will the white background of my JPG turn transparent?
No. A JPG has no transparency, so its background stays as it is; only the strips around a photo that isn’t square are clear. For a cut-out icon, start from a transparent PNG.
How big is an icon made from a phone photo?
Small. Our 5.2 MB, 12 MP test photo became a 117 KB icon with all four sizes, because the largest size is 256 px.
Where can I use the .ico file?
As the favicon of a website, and in Windows as the icon of a program, a shortcut or a folder. Google Search accepts ICO favicons too.
Does the photo stay on my computer while it becomes an icon?
Yes. Your browser decodes, resizes and packs it on your own device, and nothing is sent anywhere.
