How to convert images to PDF (free)

  1. Drop your images onto the box above, or click to choose them.
  2. Reorder them with the ↑ / ↓ arrows — each image becomes one page.
  3. Pick a page size (or Fit to image) and click Create PDF to download.

Fit to image, A4 or Letter?

Fit to image makes each page exactly the size of its picture, with no borders — ideal for scans and screenshots you want edge to edge. A4 and US Letter place each image centred on a standard printable page, scaled to fit inside your chosen margin — the right pick when the result will be printed.

Which formats work?

JPG and PNG are embedded directly with no quality loss. WebP, GIF and BMP work too: they're re-drawn as PNG in your browser first, then placed into the PDF. Animated GIFs contribute a single frame.

Why katlab's image-to-PDF tool is different

Most "JPG to PDF" sites upload your pictures to their servers. This one doesn't. The PDF is assembled inside your browser tab, so your images never touch the network — nothing to leak, cache, or delete later.

Is it really private?

Yes. There is no upload step and no account. You can open your browser's network tab and watch: no request carries your image data. The tool works offline once the page has loaded.

Will it reduce image quality?

JPG and PNG are copied into the PDF as-is, so there's no re-compression. If you need a smaller file, compress the images first with the image compressor, then build the PDF.
