Neksio Tools Image to PDF Converter is a free, lightning-fast, and completely private browser-based tool that effortlessly converts multiple photos into a single, high-resolution PDF file.

Batch Convert Up to 20 Images
Upload 1 to 20 images at the same time. Merge JPG, PNG, WEBP, BMP, GIF, and SVG into one clean PDF document without any server queues or delays.
100% Client-Side Privacy
Unlike other websites that upload your personal pictures to third-party cloud servers, our converter processes everything locally inside your browser. Your images never leave your computer or phone.
Interactive Table & Live Reorder
View all your images in an organized table with thumbnail previews, dimensions, and file sizes. Move pages up or down, rotate individual photos, or sort alphabetically before compiling.
Custom Page Setup & Margins
Choose between standard international A4, North American US Letter, or auto-fit dimensions. Control margins (Full Bleed borderless, small, or normal) to achieve print-perfect results.
Why Convert Images to PDF?
While standard image formats like JPG and PNG are excellent for photography and web graphics, sharing multiple images separately via email, WhatsApp, or official portals can be chaotic. Sending 15 individual photo attachments often leads to lost files, scrambled page orders, and upload size rejections. Converting your images to a single PDF provides several critical advantages:
- Unified Single Document: Combine multipage documents, contracts, scanned IDs, medical records, or invoices into one sequential file.
- Universal Device Compatibility: PDFs open identically across every smartphone, tablet, Windows PC, Mac, and Linux device without needing specialized photo viewers.
- Print-Ready Consistency: Standardized page sizes like A4 ensure that physical printers produce clean borders without cropping important text or edges.
- Secure & Tamper-Proof: PDF documents are harder to accidentally alter than raw image files, making them the worldwide legal standard for professional submissions.

Are my private documents and photos safe?

Choose A4 if you plan to print your document in Europe, Asia, or worldwide. Choose US Letter for North America (USA/Canada). Choose Fit to Image if you want the PDF pages to match the exact dimensions of your pictures without any white borders.
