Invert Image Colors – Negative and Dark Mode Maker

Drop a picture on the box above and see it inverted at once, with a before-and-after slider to compare. Pick one of seven modes or tap a preset, set the Strength, and press the button. You can invert image colors online here for a single screenshot or a batch of up to 100 pictures, and download one file or a ZIP.

Everything runs in your browser. Your pictures are opened, inverted and saved on your own device, and nothing is uploaded. JPG, PNG, WebP and HEIC photos from iPhones work, and most browsers also open GIF, BMP and AVIF. The saved file keeps the full resolution of the original.

Which mode is right depends on what you want the result to look like. To invert colors on photo files for a striking art effect, Full negative is the classic choice: skies turn amber, skin turns blue-green and shadows glow. Complementary colours is gentler, because light areas stay light and dark areas stay dark; only the hues swap, which often looks like a strange, dreamy color grade rather than a negative.

Luminance only does the opposite. It keeps the hue and saturation of each pixel and flips only its lightness, so a white page with black text and a red heading becomes a dark page with light text and a red heading that is still red. That makes it the best mode for turning screenshots, diagrams and scanned notes into a dark-mode version that is easier on the eyes at night.

The preview is drawn from the first picture in your list, at a smaller size for speed. The saved file is made at full size with the very same settings, so what you see on the slider is what you get.

Bright white screenshots, slides and scanned pages can be hard to read late at night or on a projector in a dark room. The Dark mode document preset uses Luminance only, which flips how light each pixel is while keeping its hue. White backgrounds turn near-black, black text turns near-white, and a blue link or a green bar in a chart stays blue or green.

Mid-tones stay roughly where they are, because a color that is half-way between light and dark is already in the middle. A pale yellow highlight therefore turns into a deep olive, and a light gray table border becomes a darker gray. Photos inside a document look strange in this mode, as they would in any dark mode; if a page is mostly photos, Full negative or no inversion at all may suit it better.

For a whole PDF rather than single pictures, Invert PDF Colors does the same job page by page. Printing a dark-mode version uses far more ink or toner than the original, so keep the inverted files for screens and the originals for paper.

Strength runs from 0 to 100%. At 100% the picture is fully inverted; below that, the inverted result is blended with the original. Around 50% most colors meet in the middle and the picture turns flat and gray, while 60 to 80% gives a soft, faded look with a hint of the negative. It works with every mode except Transparency only, which simply flips the see-through areas.

To invert image colors from black to white, Full negative is all you need: pure black (0, 0, 0) becomes pure white (255, 255, 255) and the other way round, and every gray in between lands at its mirror value. Dark text on a white page becomes white text on black, and a white signature on a dark photo becomes a dark one.

If the picture has colors you do not want in the result, choose Black & white negative. It turns the picture gray first, using the usual weighting where green counts most and blue least, and then inverts it. For a gray version without inverting, Grayscale Image does that, and for whole documents PDF to Black and White converts every page of a PDF.

A very common job is to invert image color to white: a black logo, icon or signature needs to show on a dark website, slide or video. Add it as a PNG with a transparent background, keep Full negative at 100% Strength, and leave Transparent areas on Keep transparent. The black shapes turn white, the background stays see-through, and the file is saved as PNG again.

If the logo sits on a white background instead, that white turns black. That is fine on a black page, but for a clean cut-out, remove the background first with Remove Background and invert the result. A logo in one dark color that is not black turns into a light color rather than pure white; to check the exact value, the Invert one colour box shows the opposite of any HEX code, and Color Picker reads colors from a picture.

To invert negative scan files from a color film, a plain negative is not enough. Color negative film has an orange base, so a plain inversion gives a cold, blue-cyan picture. Film negative mode deals with this. It looks at the brightest 0.5% of the picture in each channel, which on a negative is the unexposed film base, and divides that orange mask out. Then it inverts the picture. With Auto levels ticked, it also stretches each channel between its darkest and brightest 0.5%, so the result uses the full range from black to white.

Results depend on the scan. Crop away bright film holder edges, light gaps and white borders first, because the mode takes the brightest part as the film base, and a bright frame can throw the colors off. The scan should be in color, not already turned gray, and should not be clipped to pure white in the film base. Expired film, mixed lighting from a phone light pad and heavy color casts may still need fine-tuning in a photo editor afterwards; this mode gives a good, honest starting point, not a lab scan.

For black and white negatives there is no orange mask, so Black & white negative or Full negative is usually simpler. Save film results as PNG if you plan to edit them further, so no detail is lost to JPG compression.

You do not need a film scanner to try this. Put the negative on a plain white light source, such as a tablet showing a blank white page or a light pad, and photograph it straight on with your phone, filling the frame. Turn off the flash, keep the camera parallel to the film so the frame is not skewed, and avoid room lights reflecting on the film.

Then crop the photo tightly to the picture area, add it here, choose Film negative and keep Auto levels ticked. Check the preview with the slider. If the colors still lean one way, open the file in a photo editor and adjust white balance there; the inverted PNG is a much easier starting point than the orange negative.

Transparency is kept whenever the format can store it. To invert image colors PNG files with a transparent background, leave the format on Same as original or choose PNG (lossless), and keep Transparent areas on Keep transparent. Only the colors change; the alpha channel stays exactly as it was.

Transparent areas has two other choices. Fill white and Fill black put a solid background behind the inverted picture, which is useful when the result goes somewhere that does not show transparency well. JPG cannot be transparent at all, so when you save as JPG, Keep transparent fills white there.

Same as original saves PNG, GIF and BMP pictures as PNG, WebP as WebP, and JPG and HEIC photos as JPG. You can also pick PNG (lossless), JPG or WebP yourself. The Quality slider, from 60 to 100 with 92 as the default, applies to JPG and WebP. For converting between formats without inverting, Convert Image does that.

To invert colors on iPhone and iPad, you do not need an app. Open this page in Safari, tap Select images and choose photos from your library or the Files app; HEIC photos from the camera work directly. Press Invert colours and tap Download image. The file goes to Downloads in the Files app, and Share or Save Image moves it into Photos.

The iPhone also has Smart Invert and Classic Invert in its Accessibility settings, but those only change how the screen looks. The photo itself is not changed, and when you send it or open it on another device it looks the same as before. To get a picture that stays inverted, you need a new file, which is what this page makes.

You can invert colors online on any current browser. On Android, pick pictures from the gallery or the file manager, and results land in the Downloads folder. On Windows and Mac, drag pictures from a folder onto the box, or copy one and paste it with Ctrl+V. The ZIP opens with the built-in tools of every system.

Big batches of large photos need memory, so a computer is more comfortable than a phone for those. Pictures are processed one after another, which keeps memory use steady.

You can invert image colors free here with no account, no email address and no app. There is no watermark on the result, no daily limit and no trial that ends.

It can be free because your own device does the work. Inverting is a light job for any phone or computer, so there is no server to pay for and no queue to wait in.

Select many files at once or drop a pile on the box: up to 100 pictures go into one batch, with the same settings for all of them. The preview shows the first picture, so check that one before you start.

When you press the button, the pictures are inverted one after another at full resolution. The list shows the pixel size and file size of each result, and Download all (ZIP) saves every file in one archive named inverted-images.zip. Change a setting and the results are cleared, so you can try another look on the same batch without adding the files again.

Below the tool, Invert one colour turns a single color into its opposite. Pick a color with the swatch or type a HEX code such as #2563eb, and the inverted code appears next to it, here #da9c14. It is handy for designers who need the exact opposite of a brand color, for dark-mode palettes, or for checking what a logo color will become before you invert the whole picture.

Each picture is opened by your browser, turned the right way up and drawn onto a canvas at full size. Every pixel is then changed with the mode you chose, blended by Strength, and given the background you set for transparent areas. The canvas is saved as PNG, JPG or WebP. No file, preview or copy is sent to our server, so private photos and work documents stay on your device.

The saved files contain the picture only: camera details, dates and location from the original are not copied in.

At 100% Strength, inverting a result a second time with the same mode brings back the original in Full negative, Chosen channels and Transparency only, and very nearly in Luminance only and Complementary colours, apart from tiny rounding. Black & white negative removes color for good, and Film negative cannot be undone this way, so keep your original files.

If a result looks harsh, lower Strength a little rather than switching modes. If text in a scanned page looks gray instead of white after inverting, the scan was not pure white to begin with; Full negative at 100% shows exactly that, so raise the contrast of the scan first in any photo editor.

Inverted pictures often go on to other jobs. Crop Image trims the part you need, and Image to PDF puts pages together into one document. For PDFs, Invert PDF Colors turns whole pages into a dark version, and Color Palette Generator builds a palette around the colors you got.
