🪄 Drag & Drop Hero Drop files once on the home page and they follow you everywhere. No re-uploading between tools. |
🗂️ File Vault A shared in-memory vault carries your PDFs and images across every tool page automatically. |
|
🖼️ Real PDF Previews Page thumbnails render everywhere, with a graceful PDF-icon fallback if a file can't be parsed. |
🧮 Equation → Image Type LaTeX, get a pixel-tight cropped PNG for papers, reports and slides. Fraction rules now align perfectly. |
|
✍️ Sign PDF Draw a signature on a signpad, then place, drag and resize it anywhere on the page. |
📉 Smarter Compression Live preview per quality level, predicted output size, and target-size mode for PDFs and images. |
