Combine JPG, PNG, and WebP images into a single PDF, processed locally with pdf-lib in your browser, your document never leaves your device.
Your images are processed locally with pdf-lib in your browser; your document never leaves your device. Nothing is uploaded to any server.
Auto is ignored when page size is Auto, since those pages already match the image shape.
Working…
Turning a batch of photos or scans into one PDF is the standard way to attach receipts, sign documents digitally, or archive pictures in a format every device opens. This tool combines 2 to 50 JPG, PNG, and WebP images into a single PDF in the exact order you select them. JPEG and PNG files are embedded without recompression, so the pixels in your PDF are identical to the originals. WebP is not natively supported by the PDF format, so those images are converted to JPEG first using your browser's canvas.
Three layout controls shape the output. Page size chooses between A4, US Letter, or automatic pages that match each image's pixel dimensions (one pixel becomes one point at 72 dpi). Orientation forces portrait or landscape pages, or follows each image's shape automatically. Margins add white space around the image, and images placed on fixed-size pages are scaled down to fit while preserving their aspect ratio.
Everything is processed locally with pdf-lib in your browser; your images and the resulting document never leave your device. That makes the tool safe for contracts, ID scans, and other sensitive material.

JPG, PNG, and WebP files are accepted. JPEG and PNG data is embedded in the PDF directly with no recompression. WebP files are first converted to JPEG in your browser because the PDF format does not contain a native WebP encoder.
No. For JPG and PNG inputs the original image bytes are embedded as-is, so nothing is re-encoded. Only WebP files go through a JPEG conversion step. Images larger than the chosen page are scaled down to fit, which reduces their printed size but keeps the embedded data intact.
Between 2 and 50 images per PDF. Each image becomes one page. If you need more pages, create several PDFs and join them with the PDF Merge tool.
Auto creates a page with the exact pixel dimensions of each image, where one pixel maps to one point at 72 dpi. A 1920 x 1080 photo produces a 1920 x 1080 pt page. This preserves each image at full scale with no letterboxing.
No. The tool runs entirely in your browser using pdf-lib. No image data, file names, or the generated PDF are ever transmitted to a server, so the tool is suitable for confidential documents.
