Remove a color from images in bulk
Pick the color once — like a white background — and strip it from every image in the batch.
Settings
Every output is a transparent PNG.
Just one image? Use remove a color from an image.
Need more than one operation? Open the full editor to combine tools and reorder your edits.
This is the tool for a folder of logos, product cut-outs, or scanned documents that all share the same flat background. You choose the colour and tolerance once and it is applied to every file, with the results returned as transparent PNGs in a ZIP.
The tolerance setting is doing more work here than in the single-image version, because it has to absorb the differences between files. Scans lit slightly differently, or logos saved as JPEG at different quality levels, will all have marginally different "white" backgrounds — a tolerance around 20 to 30 usually covers that spread.
How it works
- 1
Drop your images onto the workspace. Sets that share a background colour work best.
- 2
Set the colour to remove using the swatch or hex field — White is preset, since it is by far the most common case.
- 3
Set the tolerance. Higher values absorb more variation between files, at the risk of eating into lighter parts of the subjects.
- 4
Click Process all, then download the ZIP. Every output is a transparent PNG.
Frequently asked questions
Can the background colour differ slightly between images?
Yes, within reason — that is exactly what tolerance is for. It absorbs compression noise and slightly off-white backgrounds across a set. If the backgrounds are genuinely different colours rather than shades of one, process them as separate batches with the right colour picked for each.
Why are the outputs always PNG?
Because PNG preserves the transparency the tool just created. Exporting to JPEG would flatten every removed area straight back onto a solid background, undoing the work. Convert the ZIP contents to WebP afterwards if you want smaller files with the transparency intact.
What if one image in the batch comes out wrong?
Because one colour and tolerance apply to everything, an image with a different background will not key cleanly. The full editor is the better tool in that case: it lets you set a batch-wide removal and then adjust individual images on top of it, stepping through them with the arrows.
Will this work on photographs?
Not well. Colour keying needs a flat, uniform background — in a photograph the "white" wall behind a subject is hundreds of subtly different greys, so no single colour and tolerance will remove it cleanly without also removing parts of the subject.
Are the images uploaded to process the batch?
No. Every file is read, keyed, and packed into the ZIP inside your browser, so a set of unreleased product images or scanned documents can be processed without leaving your device.
