How It Works

You have a stack of scans, screenshots, or phone photos and someone wants them as one file that opens the same on every device. That is what this does: feed it a batch of JPG, PNG, WebP, GIF, or BMP files and it writes a single PDF where each image becomes its own page, in the exact order you set. Add as many images as you want, then arrange them. Move any file up or down, or remove one you added by mistake, and the pages in the final PDF follow your list from top to bottom. No paper size is forced on your images either. Every page is sized to the pixel dimensions of the image it holds, so a tall phone shot and a wide screenshot each keep their own proportions, with no cropping and no letterbox bars. The embedding is format-aware. A file that is already JPEG is copied into the PDF byte for byte, so the photo is never re-compressed and looks identical to the original. PNG, WebP, GIF, and BMP files are decoded and re-encoded as PNG inside the PDF. PNG is lossless, so there is no visible quality drop, but those pages carry PNG's weight rather than the original codec's. An animated GIF contributes only its first frame, as one still page. The whole thing runs on pdf-lib in your browser. Files are read into memory, stitched into a PDF, and handed straight back as a download. Nothing touches a server, which is why it keeps working offline and why your documents never leave your machine.

Key Benefits

  • Merge many images into a single multi-page PDF in one build
  • Set the exact page order by reordering and removing files before building
  • Each page is sized to its image, so nothing is cropped or padded
  • JPEG photos are embedded without re-compression and stay pixel-identical
  • Mix formats freely: JPG, PNG, WebP, GIF, and BMP in one PDF
  • Runs fully in your browser, so files are never uploaded and it works offline

Common Use Cases

  • Combining scanned receipts or contract pages into one PDF to email or file
  • Turning a run of screenshots into a single document for a bug report or walkthrough
  • Bundling phone photos of a whiteboard or handwritten notes into one shareable file
  • Assembling a quick portfolio or moodboard from mixed image formats
  • Packaging product or property photos into one PDF for a listing or client
  • Submitting homework or forms as a single PDF instead of loose image attachments

Pro Tips

  • Arrange the file list before building; pages follow it top to bottom
  • Convert WebP, GIF, or BMP inputs to JPEG first if you want the smallest PDF
  • Resize images to matching dimensions beforehand for a uniform page size
  • Keep photos as JPG so they embed with zero re-compression
  • Split an animated GIF into PNG frames first if you need one page per frame
  • Build very large photo batches in smaller groups to avoid memory limits on weak devices

Frequently Asked Questions

Yes, that is the whole point of this tool. Add all your JPG, PNG, WebP, GIF, or BMP files at once, arrange them with the move up and move down controls, and it writes a single PDF with one page per image in that order. You are not stuck doing one file at a time.
Every file you add shows up in a list. Use the up and down controls to move any image, and remove the ones you don't want. Pages are generated strictly top to bottom following that list, so the order you see is the order you get in the PDF.
JPEG images are embedded exactly as-is with no re-compression, so those pages are visually identical to the source. PNG, WebP, GIF, and BMP files are re-encoded as PNG, which is lossless, so there is no visible quality loss either. The only trade-off is size: a WebP page stored as PNG can end up larger than the original WebP.
There is no fixed page size. Each page is built at the exact pixel dimensions of its image, so portrait and landscape images keep their own shape and nothing is cropped or padded. If you need a uniform A4 or Letter layout, resize the images to matching dimensions before you add them.
No. The entire conversion runs in your browser using pdf-lib. Your images are read into memory locally, assembled into the PDF, and returned as a download. No file leaves your device, so the tool also works without an internet connection once the page has loaded.
No. A GIF is treated as a still image and only its first frame becomes a page. If you need every frame, split the GIF into separate PNG files first, then add those files here and you'll get one page per frame.
The tool sets no fixed cap; the real limit is your device's available memory, since every image is held in memory while the PDF is built. Large batches of high-resolution photos can be slow or run out of memory on low-end devices. If you hit a wall, build the PDF in smaller batches and merge later.
Anything that isn't already JPEG is stored as PNG inside the PDF. PNG is lossless and doesn't pack photographs as tightly as JPEG or WebP, so pages made from WebP, GIF, or BMP can grow noticeably. For the smallest output, convert those images to JPEG first, then build the PDF.
