You've got a bunch of photos — scanned receipts, photos of a whiteboard, handwritten notes — and you need to send them as a single document. Sharing 15 separate image files is messy. A single PDF is much cleaner and easier for the recipient to read.
The fastest way
Go to pdfmerger.io/jpg-to-pdf. Upload your images. Drag them into the order you want — each image becomes one page in the final PDF. Click "Convert to PDF" and download. It works with JPG and PNG files.
Images are embedded at their original resolution. No compression, no quality loss.
Getting the page order right
The order you set before converting is the order pages appear in the PDF. If you're converting photos of a multi-page handwritten document, drag them into the correct sequence first. There's no reordering after conversion — you'd need to re-upload.
What page size will the PDF be?
Each image gets a page sized to match its own dimensions. A portrait photo becomes a portrait page; a landscape photo becomes a landscape page. This means a PDF from mixed-orientation images will have pages of different sizes, which is fine for reading on screen but can be awkward to print.
If you need all pages to be a standard size like A4 or Letter, you'll get better results putting the images into a Word document or Google Slides first, adjusting them to fit the page size, then converting to PDF from there.
JPG vs. PNG — which should you use?
If your images are photos of real-world objects or scenes, JPG is fine. If they contain text, screenshots, diagrams, or anything with sharp edges, PNG gives better results because it's lossless — JPG compression can make text edges slightly fuzzy. Use pdfmerger.io/png-to-pdf for PNG files.
Photos taken on an iPhone
iPhones often save photos as HEIC by default, which isn't supported. You'll need to export them as JPG first. In the Photos app, tap Share → Save to Files and it usually converts automatically. Or change your camera settings: Settings → Camera → Formats → Most Compatible, which shoots in JPG going forward.
What if you need to add a PDF to the mix?
Convert your images to a PDF first with this tool, then use the merge tool to combine it with any existing PDF documents. You can build up a final document from any combination of images and PDFs that way.
