JPG to PDF — Convert Multiple Images to One PDF (Browser)
ImageJPG to PDF is a browser-based converter that places multiple JPG and PNG images, one per page in the order you set, into a single PDF file.
What is it
Convert JPG to PDF when submitting scanned photos, receipts, or assignment pictures as one document. Add images, drag to reorder, then choose the paper size (A4, Letter, or fit-to-image) and margin in millimeters; each image gets its own page and is scaled to fit inside the margins while keeping its aspect ratio. JPG data is embedded as-is without recompression, so there is no quality loss, and PNG keeps its transparency. Files up to 50MB each are supported and all conversion runs in the browser.

FAQ
Are my images uploaded to a server?
No. Image selection, PDF creation, and download creation all run in your browser; the files never leave your device.
Do images lose quality?
No. JPG data is embedded into the PDF without recompression and PNG is embedded losslessly, so quality is preserved.
How do I set the image order?
After adding images, drag items in the list or use the up/down buttons; pages are created in that order.
Can I add HEIC photos?
No. This tool supports JPG and PNG only. Convert iPhone HEIC photos with the HEIC to JPG converter first.
