Convert an image to a transparent PNG.

No. JPG stores only red, green and blue; there is no alpha channel to hold a transparent pixel. To get transparency out of a JPG, the image has to be rewritten as PNG, which is what this tool does: it decodes the JPG, removes the background color and writes a PNG with an alpha channel.

Anything your browser can decode: JPG, PNG, WebP, GIF, AVIF, BMP, ICO and SVG. Each is decoded to pixels, so the source format stops mattering once it is in; the result is always a PNG.

Often, yes. PNG is lossless and keeps every pixel, while JPG throws detail away to get small, so a photo that was 300 KB as a JPG can be a few megabytes as a PNG. For the web, run the result through the PNG compressor or convert to WebP, which keeps the transparency at a fraction of the size.

This tool selects by color, which is exact and fast when the background is one flat tone: a white studio sweep, a green screen, a logo on a plain fill. Machine-learning removal finds the subject instead and works on busy photos, but it guesses at edges and runs a model. For a solid background, color selection gives a cleaner cut.

When an image loads, the tool samples its border and picks the most common color there, which is the background in nearly every product shot, logo and scan. Open the picker to change it, type a hex code, or press From edges to sample again after you have changed it.

Tolerance decides how close a pixel's color must be to the picked color to become transparent, as a percentage of the distance between black and white in RGB. At 0 only an exact match goes; at 10 to 20, nearby shades go too. Raise it when a background has gradients, shadows or JPG noise, and lower it when it starts eating into the subject.

With Outer only on, the tool flood-fills from the four edges of the image and only pixels connected to the border become transparent. The same color inside the subject stays: white text on a logo survives the removal of its white background. Turn it off to remove the color everywhere, including enclosed areas.

Smooth edges blends the boundary between the removed area and the subject: within the chosen radius, pixels are made partly transparent instead of fully, so the cut is anti-aliased rather than jagged. A radius of 1 or 2 pixels suits logos and screenshots; 4 or more softens photos. It only affects pixels that were already going to be removed.

No. Your browser decodes the file and does the pixel work with its Canvas API, and the page makes no request with it. You can load the page, go offline and keep working; the download is written from memory on your device.

No. The "Convert an image to a transparent PNG" tool is free and opens without a sign-in, an account or an install.

Nothing. The "Convert an image to a transparent PNG" tool holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
