How to convert JPG to ICO
ICO is what browsers and Windows expect for icons, so converting a JPG to ICO is normally the last step before adding a favicon to a website or an icon to a desktop application.
- Click the Choose Files button and select your JPG files.
- ICO is already selected as the output. Click the gear if you want to adjust quality or resize.
- Click Convert, then hit Download to save your ICO files, or grab them all as a ZIP.
Built for JPG files
Drop in as many JPG images as you like and they all come out as ICO. You can also change the output on any individual file if you need a mixed batch.
Keep the quality
Adjust quality per file and resize on the way through. Formats without transparency get a clean white matte instead of the black edges most converters leave behind.
Nothing is uploaded
Your files are read and written by your own browser. They are never sent to a server, so there is nothing to delete afterwards and no size or file-count limit.
More image tools
Three separate tools, all running the same way — entirely inside your browser, with nothing uploaded.
The compressor is the one to use when you want a smaller file without changing its format — it can hit an exact target file size, which the converter cannot. The resizer handles exact dimensions and ready-made presets for Instagram and YouTube, including common sizes like 1920×1080 and 1080×1080.
A few things are built into this converter and need no separate tool:
- Compress without converting — pick the same format as your input and lower the quality slider to shrink a file while keeping its type.
- Resize — open the gear on any file and set a maximum width; the height follows automatically.
- Images to PDF — choose PDF as the output to turn a photo or scan into a document.
- Make a favicon — choose ICO as the output to produce a browser icon from any square image.
What is a JPG file?
JPG stands for Joint Photographic Experts Group. JPG is the most widely supported image format in existence. It uses lossy compression, discarding detail the eye is unlikely to notice in order to produce a much smaller file.
JPG cannot store transparency, and repeatedly re-saving a JPG degrades it a little each time.
What is a ICO file?
ICO stands for Icon. ICO is the container Windows and web browsers use for icons. A favicon — the small image beside a page title in a browser tab — is normally an ICO file.
It is only meant for small square icons and has no use as a general image format.
JPG to ICO: workable, but PNG is the better source
This produces a valid icon file, with one limitation worth understanding first. JPG has no transparency, so the icon will have a solid rectangular background. In a browser tab that means a visible block of colour behind your mark rather than it sitting cleanly on the tab background — and it will look wrong against either a light or a dark browser theme, whichever you did not plan for.
If you have any version of the artwork with a transparent background, use the PNG to ICO converter instead. Use a square source of at least 256 pixels either way, and remember the icon will most often be seen at 16 pixels, where fine detail disappears entirely.

Frequently asked questions
Can I make a transparent icon from a JPG?
No. JPG cannot store transparency, so the icon will have a solid background. To get a transparent favicon you need a source image with an alpha channel — a PNG, WebP or AVIF.
Will converting JPG to ICO improve the quality?
No. Detail already discarded by JPG cannot be recovered. What converting to ICO does is stop any further loss, so the image will not degrade again on the next save.
Is there a limit on file size or how many files I can convert?
No. Conversion runs inside your browser rather than on a server, so there is no upload, no queue and no cap. Very large images may simply take a moment on a slower device.
Are my JPG files uploaded anywhere?
No. Your files are read and written by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and the converter will still work.
