Image to PDF Converter

Turn a Stack of Photos and Scans into One Tidy PDF

Loose images are awkward to send and easy to lose track of. A landlord wants four photos of a leaky tap in one attachment, an accountant wants every receipt for the month in a single file, and a tutor wants ten phone snapshots of a marked-up worksheet bundled in reading order. This tool solves that by stitching your images into one PDF, with each picture placed on its own page in the sequence you choose. It runs entirely in your browser using the jsPDF library, so the photos you drop in — whether they are private receipts, ID scans, or family pictures — are read straight from your device and assembled locally. Nothing is uploaded, there is no sign-up, and the finished PDF downloads the moment it is built.

You can add up to 20 images at a time, with each file up to 20 MB, and the converter accepts the formats people actually have on their phones and computers: JPG, PNG, GIF, BMP, and WebP. Before you convert, every image appears as a thumbnail so you can confirm you grabbed the right pictures and remove any you did not mean to include. Three simple controls — page layout, page size, and image order — let you shape how the final document looks without wrestling with a full design program.

Step-by-Step: Building Your PDF

1. Add your images. Drag and drop them onto the upload area or click to browse. You can select several at once, and you can keep adding more until you reach the 20-image limit.
2. Check the thumbnails. Each image shows up in a preview grid with its file size. Use the small red × button on any thumbnail to drop an image you do not want.
3. Choose a page layout. "One image per page" places each picture on its own page at a sensible size; "Fit images to page" scales each image to fill the page within the margins.
4. Pick a page size. Select A4, US Letter, or Legal depending on where the document will be printed or filed.
5. Set the image order. Keep the order you uploaded in, sort alphabetically by filename (A–Z), or reverse the sequence.
6. Click "Convert to PDF." The file is built in your browser and saved as images-to-pdf.pdf straight to your downloads folder.

Getting the Page Order Right

Order matters more than people expect, because a PDF is read top to bottom and page one sets the tone. The fastest way to control sequence is to name your files before you upload — 01-cover.jpg, 02-page.jpg, 03-signature.jpg — and then choose the Alphabetical (A–Z) sort so the document assembles itself in the order you intended. If your camera already saved the shots in the right sequence, leave the setting on Upload order and they go in exactly as you added them. The Reverse order option is handy when a scanner or phone saved a multi-page document back to front, which happens often with automatic document feeders.

Choosing Layout and Page Size

The two layout modes solve different problems. One image per page keeps each picture close to its natural proportions and is the right pick for a photo album, a portfolio, or a set of inspection shots where the subject should not be stretched. Fit images to page scales each picture up to the page edges within a small margin, which looks cleaner for full-page scans of paperwork, contracts, and forms where you want the document to dominate the page. Whichever mode you pick, every image is centered, and an image larger than the page is automatically scaled down so nothing is cropped off. For page size, A4 is the standard for most of the world, US Letter suits North American printing, and Legal gives extra height for long forms, tables, or contracts.

Real-World Uses

• Expense and receipt reports: Photograph a month of receipts and combine them into one PDF to attach to an expense claim instead of sending a dozen separate images.
• Submitting scanned documents: Turn phone snapshots of a signed lease, a permission slip, or a multi-page form into a single file a portal will accept.
• Photo portfolios and proofs: Bundle product shots, artwork, or property listing photos into one shareable document with a predictable page order.
• Homework and study notes: Combine pictures of handwritten pages or a whiteboard into one PDF that is easy to email to a teacher or classmate.
• Insurance and warranty claims: Group damage photos and a copy of the receipt into a single attachment that tells the whole story at a glance.

Tips for the Best Results

• Rotate before you upload. The converter places images as they are, so if a photo is sideways, rotate it in your phone's gallery first and it will appear upright in the PDF.
• Match the page size to the destination. If the PDF will be printed in North America, choose Letter; for the rest of the world, A4 avoids the document being rescaled by the printer.
• Use "Fit to page" for paperwork, "One per page" for photos. Documents look better filling the page; photos look better at their natural shape.
• Keep files reasonably sized. Very large photos make a heavier PDF. If the final file is too big to email, run it through a PDF compressor afterward.
• Name files for order. Numbered prefixes plus the alphabetical sort is the most reliable way to lock in a specific sequence.

Common Problems and Troubleshooting

• "Maximum 20 images allowed." You have reached the per-batch limit. Build one PDF from the first 20 images, then create a second PDF for the rest, or remove some thumbnails first.
• An image was rejected. Files must be a supported image type and under 20 MB each. A very large photo can be resized in your gallery app before uploading.
• A photo appears rotated. Some phones store orientation in metadata that is not always applied. Rotate and re-save the image before adding it.
• The pages are in the wrong order. Switch the Image Order control, or rename your files with numbered prefixes and use the alphabetical setting.
• The PDF looks too large in file size. High-resolution photos produce big PDFs. Compress the images first, or run the finished PDF through a compression tool.

How It Works in Your Browser

When you add images, your browser reads them into memory and shows each one as a local preview using an object URL — a temporary reference that points at the file on your own machine. On conversion, jsPDF creates a new document at your chosen page size, adds a page for each image in the order you selected, centers and scales every picture to fit, and then triggers a download. Because the entire pipeline runs in JavaScript on your device, no image is ever sent to a server, which makes the tool safe for receipts, identity documents, and anything else you would not want passing through someone else's computer. Close the tab and every image is cleared from memory.
