The eraser tool takes any picture and lets you rub parts of it out to transparent - the eraser from an image editor, as a web page, with nothing to install. Erasing images this way works on photos, screenshots, scans and logos alike. Pick Erase, set the brush size and hardness, and paint over what should go - a person who wandered into the shot, a logo in the corner, the background around a product photo you want to drop onto a coloured page. Anything you erase shows the checkerboard underneath so you can see exactly what is transparent. Made a mistake? Switch to Restore and paint the original pixels straight back, or use Undo. Nothing here touches the picture itself: the tool keeps a separate mask of what stays and what goes, so you can go back and forth as often as you like before you download.
A photo on a white wall, a product on a plain sheet, a portrait against the sky - for those the Magic brush is faster and safer than the plain eraser. It remembers the colour under the spot where your stroke starts and, as you paint, erases only the pixels that look like it. Run it along the outline of a person and the background goes while the hair, the shoulder and the shirt stay, because they are a different colour. The Tolerance slider decides how similar is similar: low values only catch the exact shade, higher values also take the faint shadows and gradients around it. For a plain background there is Color: press, drag the target onto the shade you want gone and let go - every pixel of that colour anywhere in the picture goes - the wall behind a portrait, the white of a product shot, the paper around a signature - with the same Tolerance slider deciding how far from the tapped shade it reaches. If a stroke or a tap swallows too much, undo it and lower the tolerance; if it leaves specks, raise it or finish with the Erase brush.
On a touch screen the brush works a little above your fingertip, with a ring showing exactly where it acts and a dot where your finger is, so your hand never hides the spot you are erasing. A magnifier in the corner of the picture follows the stroke at two and a half times zoom - toggle it with the magnifier button if you prefer the plain view. Pinch to zoom into the picture itself, up to eight times, and the zoomed view is cut from the full-size photo rather than the preview, so a strand of hair or the edge of a logo is drawn at its real pixels; Zoom mode pans with one finger and a double tap fits the picture again. On a computer the mouse wheel zooms in any mode. Undo is one tap away, and the picture keeps at least half the screen while the controls scroll beneath it.
The result downloads as PNG by default, the one everyday format that keeps transparency at full quality, at the original pixel size of your picture. WebP also keeps the transparent areas in a smaller file. JPG cannot hold transparency, so choosing it fills the erased parts with white - handy when you only wanted an object cut out on a clean white ground. The Copy button puts the transparent image on your clipboard for pasting into a document or another editor, and on a phone the Share button sends it straight to another app.
An eraser is usually pointed at something you would rather nobody saw - a face, a licence plate, an address on a letter, a name on a screenshot. This page never sees any of it. The picture is decoded in your browser, the mask you paint lives in your browser's memory, and the transparent PNG is assembled there too. No upload, no account, no copy on a server that could be kept; close the tab and it is gone.
Open the picture, choose Color, press on the background, move the target onto the shade you want gone and let go: every pixel of a similar colour anywhere in the picture turns transparent in one go. For a background that is not one flat colour, paint along the subject's outline with the Magic brush - it only takes colours like the one the stroke started on - then download as PNG so the transparency is kept.
Brush size is a share of the picture, so a stroke covers the same part of the image on the screen and in the downloaded file. Hardness is how sharp the rim is: at 100 percent the brush cuts a crisp circle, at lower values it is solid in the middle and fades out towards the rim, which blends far better around hair, fur and soft shadows. The Magic brush has no hardness - its edge is the colour test.
Yes, in three ways. Undo removes the last stroke (Ctrl+Z, and Ctrl+Y brings it back), Restore all puts the whole picture back, and the Restore brush paints the original pixels back only where you drag it - useful when a Magic stroke took a piece of the subject along with the background.
No. The picture, the mask you paint and the finished PNG all stay in your browser. That matters for an eraser more than for most tools, since what people erase is often exactly the part they do not want stored anywhere.
