Negative to Positive Converter

What “negative to positive” actually involves

On a negative, everything is reversed. Bright parts of the scene are dark on the film, shadows are nearly clear, and on color film each color is recorded as its opposite: skies look yellow-brown and grass looks magenta. Converting a negative to a positive restores normal tones and colors.

For black-and-white film that reversal is most of the job. Color negatives need one more step, because the film itself is tinted orange. Reverse a color negative without dealing with that tint and the whole picture turns blue. This converter measures the tint from the film and takes it out before it rebuilds the colors. The tint is called the orange mask, and it is there on purpose.

Bringing old family negatives back

Strips of negatives often outlast the prints that were made from them. If you have a box of them and no scanner, a phone and a white screen are enough to start: lay the strip on a tablet or laptop showing a blank white page, photograph one frame at a time, and open each photo here. Our guide to digitizing negatives with a phone covers the setup in detail.

Convert one frame per image. If your photo shows several frames at once, use the crop tool to pick one; the colors are worked out from the area inside the crop, so a tight crop usually gives a better result than a whole strip.

Faded or badly stored film may not look right on the automatic setting. The film base picker, the neutral gray picker, and the sliders are there for those frames.

This is for film, not for inverting ordinary images

If you want to flip the colors of a regular photo, a logo, or a screenshot, a plain “invert colors” tool is the right choice and will give you an exact mathematical inverse. This converter does something different: it assumes the image is a piece of film and corrects for how film records light, so it will not produce a simple inverse.

Getting a positive that looks right

• Photograph the negative in a dim room so the only light comes through the film.
• Keep a thin edge of blank film in the shot when you can. It tells the converter what the film’s own color is.
• If text or faces come out mirrored, the film was photographed from the back. Use Flip to turn it around.
• Slides are already positives. They do not need converting, and this tool is not meant for them.
• For black-and-white film, switch the film type to “Black & white” so no color correction is applied.

Frequently asked questions

Is converting a negative to a positive the same as inverting the colors?

For black-and-white film it is close. For color film it is not: color negatives have an orange tint built in, and each color layer has its own contrast. A straight invert leaves a strong blue cast, so the tint has to be removed and the layers balanced as part of the conversion.

Can I convert negatives without a scanner?

Yes. Photograph the negative with a phone or camera while it is lit evenly from behind, for example on a tablet showing a white screen, then open the photo here. A scanner gives more detail, but a careful phone photo is enough for sharing and for small prints.

Why is my positive mirrored or upside down?

The negative was scanned or photographed from the other side, or loaded the other way up. Use Flip and Rotate 90° under the preview to correct it. The exported file keeps the orientation you set.

Do I need Photoshop or any other software?

No. The conversion runs in your web browser and there is nothing to install. If you would rather do it by hand, our Photoshop guide walks through the manual steps.

Can I convert a whole strip or several negatives at once?

Not yet. The tool handles one image at a time and works best with one frame per image. For a strip, open the image, crop to a single frame, download it, and repeat for the next frame.

What size and format is the positive?

You can save a JPEG or a PNG at the same pixel dimensions as the image you opened, or smaller if you cropped it. On some phones a very large image is reduced to the largest size the device can handle, and the page shows the final size when that happens.
