PNG Background Removal in n8n

1. 1Trigger node — start on schedule, webhook, or file watch. Pass the image file path or binary data forward.
2. 2Read Binary File node — if you are working with local files, load them into the workflow as binary data.
3. 3Execute Command / Code node — run the Playwright script below to process the image in PNGmaker.
4. 4Write Binary File / Move node — save or route the output transparent PNG to your destination (S3, local folder, email, Slack, etc.).

This script uses stable data-testid attributes from PNGmaker's agent-optimized page:

// n8n Execute Command node (runs Playwright script)
// Place this in an "Execute Command" or "Code" node

const { chromium } = require('playwright');

const inputPath = $input.item.binary.data.filePath;
const outputPath = inputPath.replace(/\.\w+$/, '-transparent.png');

const browser = await chromium.launch();
const page = await browser.newPage();

await page.goto('https://pngmaker.com/remove-background/agent');

const input = await page.locator('[data-testid="bg-removal-dropzone"] input[type="file"]');
await input.setInputFiles(inputPath);

await page.waitForSelector('[data-testid="bg-removal-result"]', { timeout: 30000 });

const downloadPromise = page.waitForEvent('download');
await page.click('[data-testid="bg-removal-download"]');
const download = await downloadPromise;
await download.saveAs(outputPath);

await browser.close();
return { outputPath };
