How to convert QOI to JPG

  1. Add your QOI images

    Drop QOI files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. JPG is already chosen

    Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.

  3. Download

    Save the JPG, or download everything as one ZIP if you converted several files.

Why ToAny

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

QOI to JPG: what to expect

QOI opens in very few apps, and no browser shows it. JPG opens on every device and is accepted by practically every upload form. QOI is at home in game textures and pipelines that need very fast encoding; JPG is the usual choice for photos you need to share, upload or print. JPG is lossy, so keep the QOI original if you may need full quality later.

JPG has no transparency, so see-through areas of a QOI are filled with a solid colour, white by default; you can change it under Options. The defaults suit most files. Under Options you can set the quality, aim for a target file size and resize the result.

QOI vs JPG

QOI

QOI image

QOI is a lossless image format with a specification short enough to read in a few minutes. It compresses far less than PNG but encodes and decodes many times faster, which is why game developers and tool authors like it. Support in everyday apps is thin.

Opens in IrfanView, XnView, many game engines and graphics tools; no browsers or phones

JPG

JPEG image

JPG (also written JPEG) is the format almost every camera and website uses for photographs. It throws away detail the eye barely notices to keep files small, which is why it suits photos and struggles with sharp text or flat colour.

Questions

Are my images uploaded anywhere?

No. The QOI to JPG conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Does converting QOI to JPG reduce quality?

JPG is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can raise or lower the quality under Options.

Can I convert several QOI files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert QOI to JPG on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the QOI file, press Convert and save the JPG. There is nothing to install.

Is there a file size limit?

Pictures of up to 120 megapixels are accepted (for example 12,000 by 10,000 pixels); a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
