Photos are easy to take and easy to share one at a time, but the moment you need to send several of them together — scanned pages of a contract, receipts for an expense report, photos of a whiteboard from a meeting, or pages of handwritten notes — a single PDF is far more useful than a folder of loose image files. This tool takes one or many JPG or PNG images and stitches them into one PDF document, in the order you added them, with each image automatically placed and sized to fit neatly on its own page.
The process is genuinely simple. Drop your images into the box above, or click it to open your device's file picker and select several at once. Each image you add shows up as a small chip below the drop zone so you can see exactly what is queued up, and you can remove any image you added by mistake before converting. Press Convert to PDF, and the tool works through your images one at a time, placing each on its own A4 page and centring it so there is no awkward stretching or cropping.
It automatically figures out whether an image is landscape or portrait and scales it to fit the page while keeping its original proportions, so a wide photo of a document does not end up squeezed or distorted. Both JPG and PNG formats are supported, and you can mix the two in a single conversion — the tool checks each file individually rather than assuming every image is the same type, which matters because PNG and JPG are encoded differently internally.
This tool is genuinely popular for a reason: turning a stack of phone photos of paperwork into one clean PDF is one of the most common small tasks people run into, whether it's for submitting a form, archiving receipts, putting together a simple photo album, or sending scanned ID documents that a company has asked for as a single file rather than five separate attachments. Because the order of the images in the final PDF matches the order you added them, it helps to select or drag your files in the order you want them to appear in the finished document.
If you are combining photos of a multi-page document, taking each photo from directly above the page (rather than at an angle) and making sure the whole page is inside the frame will give you the cleanest, most professional-looking result once everything is placed on its own PDF page. It also helps to review the order of your file chips before converting, since reordering after the fact means removing and re-adding files rather than dragging them into place.
Everything happens on your own device. Each image is read directly by your browser and drawn onto a PDF page using JavaScript — nothing is uploaded to a server, which means there is no realistic limit on how many images you can combine (aside from your device's own memory), no waiting for an upload to finish, and complete privacy for anything sensitive like ID cards, medical documents, or financial paperwork. The tool is free with no watermark, no sign-up, and no cap on how many times you use it.
