JPG to ICO Converter

Drop a JPG, get a ICO. Nothing is uploaded.

Resize

The shape is always kept, so the other side follows. Neither maximum ever ENLARGES a picture that is already smaller than it.

Pixels for either maximum, and a percentage for the last one. It is ignored while Resize is keeping the original size.

Nothing is uploaded. Your file is read in your browser and never leaves your computer.

What this does

Every camera and every phone writes JPG. An ICO is what a browser tab and a Windows shortcut ask for by name, and neither of them accepts anything else in its place. It is what a photograph of a print arrives as, and what a listing wants back.

How it works

  1. Choose your JPG fileDrag a JPG file onto the box above, or press it and pick one. It is read in your browser, so nothing is uploaded.
  2. Wait for the ICOThe conversion runs on your own computer, so how long it takes depends on your machine and the size of the file, not on a queue.
  3. Download the ICOPress the download button. The ICO file lands in your downloads folder, ready for your slicer.

About the formats

Why your file is a JPG
JPEG. Every camera and every phone writes JPG.
Why you want a ICO
Windows Icon. An ICO is what a browser tab and a Windows shortcut ask for by name, and neither of them accepts anything else in its place.
What a ICO holds
Several sizes of one small square in a single file, each with its own transparency, so a browser can take whichever size it needs.
What changes on the way to ICO
Big pictures are reduced until their longest side is 256, and the result stays a solid rectangle: a photograph never had the see-through corners an icon usually wants.
Where this format turns up
It is what a photograph of a print arrives as, and what a listing wants back.

Questions

Is JPG to ICO Converter free?

Yes. Every tool on Short Work Tools is free, with no account, no sign-in and no limit on how many files you run through it. It runs on your own computer, so it costs us nothing to give away.

Is my file uploaded anywhere?

No. Nothing is uploaded. Your file is read in your browser and never leaves your computer. There is no upload step, no server copy and nothing kept afterwards, which is also why it works with the network switched off once the page has loaded.

What does the ICO keep from the JPG?

Several sizes of one small square in a single file, each with its own transparency, so a browser can take whichever size it needs. Big pictures are reduced until their longest side is 256, and the result stays a solid rectangle: a photograph never had the see-through corners an icon usually wants.

How large a file can I use?

Up to 250 MB. The limit is your browser's memory rather than an upload size, because the file never goes anywhere; a file larger than that is refused with a message rather than crashing the tab.

Which programs write JPG files?

Every camera and every phone writes JPG. It is what a photograph of a print arrives as, and what a listing wants back.

Does the converted picture keep the information the camera wrote into it?

No, and there is no setting for it because there is nothing to set. The picture is decoded to pixels and drawn onto a fresh canvas, and a canvas has no place to put the camera model, the date or the GPS position the original carried, so none of it is in the file you get back.
