What is this tool?
PDF Thumbnail Generator is a free online tool that lets you generate custom image previews and thumbnails from any PDF document. The tool runs 100% locally inside your web browser, which means your documents are never uploaded to any remote server. Your privacy is fully protected, making it safe for confidential contracts, business reports, and personal PDFs. You can choose from various preset thumbnail sizes (Small, Medium, Large) or set a custom width, adjust the image format (PNG, JPEG, WebP), specify page ranges, and set a custom background. The generated thumbnails can be copied to the clipboard with one click or downloaded individually, or exported together as a ZIP file.
