JPG to PDF: Turn Photos into a Document
Scanned pages, receipts, ID photos — all in one tidy PDF.
Sending phone photos of documents one by one looks messy, and the recipient usually wants a single PDF anyway. This tool converts your JPG and PNG images into one PDF in the order you add them — each image becomes a page. In A4 mode the image is centered on a standard page with its aspect ratio preserved, ready to print; in "Image size" mode the page takes the image's own dimensions so nothing is cropped or scaled. The crucial difference is privacy: your images are never uploaded to any server — conversion happens entirely in your browser. IDs, invoices, contracts: convert sensitive photos with complete peace of mind.

Frequently Asked Questions
Are my images uploaded to a server?
No. Conversion runs entirely on your device using the pdf-lib library in your browser; your images never touch the internet. That makes it safe for sensitive photos like IDs and documents.
Which formats are supported?
JPG (JPEG) and PNG. Phone formats like HEIC need converting to JPG first — most phones do this automatically when sharing. For WebP, save the image as PNG first.
What's the difference between A4 and image size mode?
In A4 mode every page is standard A4 and the image is centered with its aspect ratio preserved — ideal for printing. In image size mode the page adopts the image's pixel dimensions, preserving it exactly.
Can I reorder the images?
Images enter the PDF in the order you add them. If the order is wrong, remove items with × and re-add them in the right sequence — you can add files one at a time.
Does quality drop?
JPG images are embedded as-is without re-compression, so there's no quality loss. PNGs transfer losslessly too. The PDF ends up roughly the combined size of the images.
How many images can I add?
There's no hard limit; since processing happens in your device's memory, the practical limit depends on your hardware. Dozens of photos work fine — hundreds of very high-resolution images may slow things down.
