Free PHP File Preview
A free PHP preview tool you can use online with no sign-up or install. Upload a single PHP file, or HTML, CSS, JS, images, and multiple pages together, or a whole folder, and relative paths and page navigation preview as-is. Paste code and the result appears live on the right. Switch between desktop and mobile widths to check responsive layouts, open in a new window, or download. All processing happens in your browser, so your files are never sent anywhere.
How to use
- Drag and drop or click to upload the PHP file you want to preview. Drop HTML, CSS, JS, images, multiple pages, or folders into the "Add files/folders" area to include them, or create them directly with "New file" / "New folder" or by pasting code.
- Click a file in the "Files" list on the left to open its code. Choose a PHP or HTML file to preview that page.
- When you edit the code area, the result on the right updates live while "Auto refresh" is on. Clicking a link inside the preview navigates to that page.
- Switch the preview width between desktop, tablet, and mobile to check responsive layouts.
- Use "Open in new window" for full-screen viewing, "Download" to save the current file, and "Copy" to put the code on your clipboard.

Frequently asked questions
Is the PHP file preview free?
Yes, it is completely free. You can use it right in your browser with no sign-up or software install.
Are my uploaded PHP files sent to a server?
No. Reading files and rendering the preview all happen inside your browser, and files are never sent to any external server.
Can I preview by typing code directly?
Yes. Without uploading a file, paste or type PHP code and the result appears live on the right.
Can I preview a project or folder with separate HTML, CSS, JS, and images?
Yes. Upload multiple files together or a whole folder, and HTML, CSS, JS, and images linked by relative paths are applied automatically, with link navigation between pages. .php files run through an in-browser PHP subset interpreter for basic syntax (echo, variables, arrays, conditionals, loops, common built-in functions). However, since there is no server, server features like DB connections, file reads, and network requests, or code that loads files via fetch at runtime, do not work.
Can I check how it looks on a mobile screen?
Yes. Switch the preview width between desktop, tablet, and mobile to see how the responsive layout looks.
Does JavaScript inside the preview run?
Yes. The preview runs in an isolated sandbox frame, so you can check PHP output and JavaScript behavior without affecting the page.
