Invert PNG Colors — Flip Black to White

Yes. The inversion touches only the red, green and blue values and never the alpha channel, so transparent and semi-transparent pixels keep their original opacity. Your file downloads as a PNG with transparency intact.

That tool flattened your image onto a solid color, which usually happens when it exports a JPG. This tool always exports PNG for PNG uploads, so the clear areas stay clear.

No. The picture keeps its original resolution up to ~16 megapixels; larger images are scaled down once for browser compatibility. The download is a lossless PNG with no compression artifacts and no watermark.

This page inverts the whole image in one pass. If you need a selective effect — one element left in its original colors — use Edit PNG Colors, where the bucket and per-color tools let you target specific shapes instead of the entire canvas.

Yes. JPG, WebP, GIF and BMP files invert just as well, and those downloads keep a familiar format (re-encoded through the browser's canvas — see the note above). PNG uploads are special: they always come back as lossless PNG so the transparency survives untouched.

Inverting is the one-click way: black flips to white and white to black in the same pass. This is a full negative — every other color flips too, which is usually what you want for icons and dark-mode assets. If you need only the black swapped while other colors stay put, that is a recolor job for PNG Color Changer.

Most scanners expect dark modules on a light background. If your QR was light-on-dark, inverting it turns it into the classic dark-on-white layout and scanning usually works again — test by pointing your camera at the downloaded file. If it still fails, the quiet zone (the white border) may have been lost; rebuild the QR rather than stacking more filters.

Yes — inverting an X-ray or a black-and-white scan of a film negative shows it the way it looks as a print, and this page handles both. Color film negatives are a different beast: they carry an orange color mask that a straight RGB flip does not remove, so use the dedicated film negative converter for those, or Negative Image Maker to create negatives from ordinary photos.

Windows 10's built-in Photos and Paint apps have no one-click invert, so the quick route is a browser tool: open this page in Edge, drop the image (PNG, JPG or WebP all work), and press Download. It runs entirely in the browser on your PC — no install, no upload.
