Getting rid of the white square
A logo saved as a JPG always carries a rectangle of white with it. JPG has no way to store transparency, so the empty space around the mark has to be some colour, and it is nearly always white.
That looks fine on a white page and wrong everywhere else. Put it on a dark header, a photograph or a coloured card and the square appears. A transparent PNG puts the mark on any background you like and shows whatever sits behind it.
Without losing quality
PNG is lossless, so nothing is thrown away in the saving. The file you get back here is the same pixel dimensions as the one you dropped in, with no watermark and no cap, which is worth checking because several free tools quietly hand back a smaller picture.
One honest limit: a cut-out is pixels. If your designer still has the original vector, an AI, EPS or SVG file, use that for anything going to print. Vectors scale to any size and a PNG does not.
Switch Subject to Object
The fast model here is trained on people, and a wordmark is not a person. Open More options and set Subject to Object. That loads a second model built for products, marks and animals.
It’s a larger download the first time and it runs on the processor rather than the graphics card, so give it a few seconds. After that it stays on your device.
Hard edges and thin type
Logos are mostly straight lines and flat colour, which cut out cleanly. Thin lettering is where it goes wrong: strapline type and hairline rules can come out broken.
Open Edges and push the grow slider out a pixel or two, which thickens the whole outline and usually restores them. If a piece is still missing, the brush will paint it back in, and you can start the stroke outside the picture and drag inwards.
Preparing a run of them
Drop a whole folder at once. Each logo queues along the bottom and Download all gives you a zip. If they’re going onto a marketplace listing, turn on Crop tight to the subject, choose a square shape, and set how much of the frame the mark should fill.
Questions
How do I remove the white background from a logo?
Drop the logo file onto this page. The background is removed in about a second and you download a transparent PNG. Switch Subject to Object first if the logo is a mark or wordmark rather than a person.
Will it lose quality?
No. PNG is lossless and the file you download is the same pixel size as the one you dropped in. Nothing is resized, recompressed or watermarked.
Why does my logo still show a white square?
Because it was saved as a JPG somewhere along the way. JPG cannot store transparency, so every transparent pixel becomes white. Save as PNG or WebP instead.
Can I get a vector file back?
No. This produces a transparent PNG, which is a grid of pixels. If you have the original vector from whoever designed the logo, that will always beat a cut-out for print.
