I’m seeking a solution that renders the top part of a webpage into a PNG image using a headless browser, deployable on my server.
I recently tackled this by using Puppeteer with headless Chrome, and it worked well for capturing just the upper section of a webpage. Configuring the viewport to match the desired portion of the page and using the clip option in the screenshot command allowed me to define a specific area for the PNG output. The process was straightforward once I set the correct parameters, and it was efficient on my server setup. This approach should nicely fit your requirements with minimal modification to the basic script.
I recently worked on a project where I needed to capture a specific region at the top of a webpage using a headless browser. In my case, I experimented with both Puppeteer and Playwright, finding that both tools offer reliable ways to set up custom clipping coordinates for screenshots. My experience taught me that waiting for the right network events is essential to ensure that all page elements load properly before capturing the image; otherwise you might end up with incomplete renderings. Another key aspect was managing viewport dimensions accurately, which proved critical in tailoring the final PNG to exact specifications on the server.
hey, try using puppeteer with a brief waitForSelector to ensure al elements load. i’ve seen that a slight delay before capturing clip helps avoid blank pics. check your dimensions and timing, sometimes hodless chrome just need a bit more time
