How to combine images into a PDF
- Drop your JPG or PNG files into the box above. Up to 50 images, 100 MB each.
- Reorder rows with the ↑/↓ buttons. The visible order becomes the page order.
- Pick a page size: Fit to image sizes each page exactly to its image, while A4 and US Letter center each image inside a standard page.
- Click Build PDF. The PDF downloads instantly.
Tips for best results
JPG images are embedded directly without re-encoding, so a JPG-only batch produces a very compact PDF with no quality loss. PNG images are also embedded losslessly. If your images mix wildly different aspect ratios, a fixed page size like A4 produces a tidier-looking document, while Fit to image avoids whitespace.
Privacy
All images are read into memory inside your browser tab. No file ever travels to a server. The PDF is built with pdf-lib and offered as an immediate download.
FAQ
Are HEIC or WebP supported? Not yet — pdf-lib only embeds JPG and PNG. Convert your images to JPG first.
How big can the resulting PDF be? The output PDF size is roughly the sum of the input image sizes (plus a small overhead). 100 MB-per-input keeps the combined size manageable.
Can I add OCR text under each image? Not in this tool — that requires a separate OCR engine. The output is image-only.
