Convert a website to an image the way each visitor sees it
Most website to image tools take one screenshot at one width. If you want to know how a page holds up on a phone, you run it again with a narrower setting and hope the site notices. Often it does not, because many sites decide their layout from the browser's identity and touch support, not just its width.
WebToImage captures the same address at Phone (390 px), Tablet (820 px), Laptop (1280 px) and Desktop (1920 px) in a single pass, plus an optional Custom width anywhere from 100 to 5000 px. For phone and tablet it emulates a mobile device and identifies as a mobile browser, so sites that serve a separate mobile layout serve it here too. The page is reloaded for every size, which means each image is a genuine render rather than one picture scaled down.
Because the capture runs on your own PC rather than on a remote server, it can reach pages a web service never could: a dev server on localhost, a staging box on your office network, or an HTML file sitting on disk.
How to test a website on different screen sizes
Enter Source URL takes an address with or without https. A bare domain works.
- Click the device drawings to choose which Screen sizes to include. A device you click again is left out.
- Include the Custom screen and set Custom ViewPort Width for a breakpoint of your own, such as 1440 or 768. Its drawing stands tall or lies flat to match the width.
- Press Convert to Image. Each device fills in with its capture as it finishes; double-click one to open the image.
- Compare them side by side in File Explorer, where each file name carries the device and width, like Pricing (Tablet 820).png.
Webpage to PNG, JPG or WebP
PNG is lossless and keeps text and interface edges crisp, which suits design reviews and bug reports. JPG and WebP are far smaller, better for email, chat or a slide. Pick Full page for the whole scroll height, or Visible area for just the first screen, the part a visitor sees before scrolling.
Sharper image (2x) doubles the pixels in each direction, the same as a high-density laptop or phone display. It is the setting to use when the images go into a portfolio, an app-store mockup or a printed proposal.
Getting a clean capture of slow or script-heavy pages
Images that wait for scrolling before loading are pulled in before the shot, so a long page does not end in empty boxes. Capture Delay (s) adds up to five seconds for carousels, fonts and animations to settle. Enable Page Javascript can be switched off to see a site's no-script fallback, Media Type set to Print shows the page with its printer styles, and a User-Agent field lets you pose as any browser you need to test.
