JPG to PDF

Drop all your JPG files onto the upload area at the same time, or click Browse and select them in your file picker. Once they're loaded, you'll see a thumbnail for each image. Drag the thumbnails to reorder pages — the topmost image becomes page 1. When the order looks right, click Convert and you'll get a single PDF with one image per page. The whole process runs in your browser, so even a batch of 20 high-resolution photos finishes in a couple of seconds. This is the same workflow regardless of whether you call it 'combine JPG into PDF', 'merge JPGs to one PDF', 'turn multiple images into PDF', or 'batch convert JPG to PDF' — they all describe this exact tool.

Up to 20 images per conversion, with each image up to 10MB. That's enough for a typical scanned document, a photo gallery, or a multi-page receipt batch. If you need to combine more than 20, run the tool twice and then merge the two output PDFs using the merge-pdf tool. The 20-image limit exists because the conversion happens in browser memory, and very large batches start to slow down on phones and older laptops. For most use cases — combining a handful of scanned pages or a dozen JPEG photos into one PDF — 20 is comfortably enough.

No. Images are embedded into the PDF at their original resolution without re-encoding. A 4000×3000 pixel JPG stays a 4000×3000 pixel image inside the PDF — the conversion just wraps the JPG bytes in PDF page structure. The output file size is roughly the sum of your input image sizes plus a small overhead for the PDF container. If you want a smaller PDF, compress the JPGs first with the compress-image tool, then run them through this converter.

No. The conversion happens entirely in your browser using the pdf-lib library. Your images are read into memory, packaged into PDF format locally, and the resulting PDF is offered as a download — none of those bytes ever leave your device. Open your browser's Network tab before converting and you'll see zero requests. This matters when you're working with sensitive scans (passports, receipts, medical documents) where uploading to a random web tool would be a privacy concern.

Each page is sized to match its source image's aspect ratio. A landscape photo produces a landscape page, a portrait scan produces a portrait page. The PDF page dimensions are scaled so the image fills the page without margins. If you need standard A4 or US Letter pages with images centered inside, run the JPGs through an image editor first to add white borders matching your target page ratio, then convert.
