Free online ORA to TIFF converter

Source format: ORA

ORA is the file extension for OpenRaster, an open, layered image format used mainly by digital artists and illustrators. It is supported by painting and image-editing applications such as Krita, MyPaint, and some other graphics tools that can preserve layers, transparency, and editing data. ORA files are typically used when you want to save a work-in-progress image with multiple layers, masks, and non-destructive editing information.

Target format: TIFF

TIFF (Tagged Image File Format) is a widely supported raster image format used in publishing, scanning, archiving, photography, and professional graphics workflows. Its main advantages are high quality, broad compatibility, and support for features such as lossless compression, transparency, and high bit depth. TIFF is often chosen when you need a durable master image or a format that many desktop applications can open.

How to convert ORA to TIFF

The best method is usually to use the application that created the ORA file, especially if you want the most accurate result. If you use Krita, follow these steps:

1. Open the ORA file in Krita.
2. If needed, check whether you want to keep the image as a flattened final version or preserve layers for editing. TIFF export usually produces a flattened image unless the software offers layered TIFF options.
3. Choose File → Export.
4. Select TIFF as the output format.
5. Adjust export options such as compression, color profile, and bit depth if available.
6. Save the file with a .tიფ or .tiff extension.

If you prefer command-line conversion and have ImageMagick installed, you can often convert a flattened ORA image with a command like magick input.ora output.tiff. However, command-line support for ORA depends on how your ImageMagick build handles OpenRaster files, so the desktop application method is usually more reliable.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and compatibility

ORA is layered, while TIFF is usually used as a final raster output, so the conversion commonly flattens layers. If you need to preserve editability, keep the original ORA file as your master copy. TIFF can store high-quality image data, but not every program supports every TIFF feature equally well, especially advanced compression methods, alpha channels, or layered TIFF variants. For best compatibility, use standard TIFF settings and avoid unusual compression unless you know the target software supports it.
