Formats that support transparency
PNG and WebP support transparency. SVG does too. JPG does not, so transparent areas are filled with a solid colour, usually white or black, when you save as JPG.
For logos and graphics, PNG is the most widely compatible choice. WebP often produces a smaller file with the same transparency, and SVG is ideal for simple vector shapes that need to scale. GIF also has simple on-off transparency, but it is limited to 256 colours and rarely the best choice today.
Removing a plain background
If a logo sits on a single solid colour, a colour-based tool can remove it. You pick the colour by clicking on it, set a tolerance and download a PNG.
This is not an AI cutout. The tool simply treats pixels close to the picked colour as background, which is why it works best on plain, evenly coloured backgrounds.
Limits
Colour-based removal does not recognise objects. Photos with complicated or similar-coloured backgrounds need a different approach, such as a manual cutout in an image editor.
If the subject contains the same colour as the background, for example a white logo on a white sheet, those parts may become transparent too.
Clean edges
A small amount of edge softness can hide jagged borders. Too much tolerance can remove parts of the subject, so adjust gradually and preview on a dark and a light background. Zooming in on corners and thin lines is the quickest way to spot problems before you download.
Remember that anti-aliased edges contain blended pixels, so a perfectly sharp result is not always possible on small or low resolution images. Starting from a larger original gives the cleanest outline.
Leftover light halos around a shape usually mean the tolerance is slightly too low. Holes inside the shape usually mean it is too high. If both problems appear together, the subject and background are probably too similar in colour for this method, and a manual edit is the safer route.
A worked example (illustrative)
Imagine a company logo exported as a JPG with a white background. You click the white area to pick it, start with a low tolerance and raise it little by little until the white disappears and the faint light fringe around the letters goes away. Then you check the result on a dark background and on a coloured one, because edge problems are much easier to see against a contrasting colour. If the letters are still clean, you save it as PNG.
A JPG logo may have slight colour noise around the edges, so a small tolerance is often needed rather than an exact match. Gradients, shadows and soft glows in the original are harder: a shadow is made of many shades of grey, so a single colour pick will remove only part of it. For those graphics, it can be easier to re-export the logo from its source file with a transparent background.
Step-by-step workflow
- Start with the highest quality original you have, ideally not a small or heavily compressed JPG.
- Pick the background colour by clicking on it.
- Raise the tolerance gradually while watching the preview.
- Check on both a light and a dark background.
- Download as PNG, or convert to WebP if you want a smaller file.
Common mistakes
- Saving the result as JPG, which fills the transparency again.
- Setting the tolerance too high and eating into the subject.
- Using a low resolution image, which makes edges look rough.
- Expecting a plain colour tool to cut a person out of a busy photo.
- Forgetting that animated or layered files may need to be flattened to a single image first.
- Testing only on white: always preview the transparent PNG on the background where it will actually be used.
Quick checklist
- Plain, single-colour background
- Original is as sharp as possible
- Tolerance raised step by step
- Preview checked on dark and light backgrounds
- Saved as PNG or WebP, not JPG
Doing it with DoneImg in your browser
Open the Make Transparent tool, add your image and click the background colour. Adjust the tolerance, check the preview, then download the PNG. If you need a smaller file, run it through the converter to WebP afterwards.
The image is processed in your browser and is never uploaded. That means logos, drafts and client artwork stay on your own device while you work.
Tip: if the first attempt leaves a fringe, undo with a slightly higher tolerance rather than starting over, and keep the original file so you can always try again.
