Easy Drag & Reorder

Browser-Based Processing
Images are processed in your browser while you create the PDF.
How to use
Each image becomes one page of the PDF. Drag the thumbnails to set the page order, then choose page size, orientation, and margins. Images are scaled to fit inside the margins without changing their proportions, and the PDF is created in your browser.
- Click the drop zone or drag JPG, PNG or WebP images onto it. Use "Add More Images" to add more later.
- Drag the thumbnail cards into the order you want; the first card becomes page 1. Remove an image with its × button, or click "Clear All" to start again.
- Choose the page size: A4, US Letter, or Fit to Image Size, which makes each page as large as its image.
- Choose the orientation and margin. With Auto, a wide image gets a landscape page and a tall image a portrait page; the small and big margins leave 10 mm or 20 mm on every side.
- Click "Convert to PDF Document". Each image is centred and scaled to fit inside the margins without changing its proportions, and the file is saved as converted_images.pdf.
Frequently asked questions
How do I change the order of pages?
Drag a thumbnail card to a new position with the mouse or your finger. The order of the cards is the page order of the PDF.
Are my images uploaded to external servers?
No. The images are placed into the PDF in your browser and are not sent to a LeedyBox server.
Does the PDF keep the original image quality?
LeedyBox does not reduce image resolution when it creates the PDF, but each image is stretched or shrunk to fit the page. A small image placed on a full A4 page can look soft when printed; choose “Fit to Image Size” if you want each page to match its image.
Why do some pages have white borders?
Images keep their proportions. When an image has a different shape from the page, for example a wide photo on a portrait A4 page, the rest of the page stays white. Choose Auto orientation, or Fit to Image Size with no margin for pages without borders.
How large are the pages with “Fit to Image Size”?
Each image pixel becomes about 0.26 mm, as on a 96-pixel-per-inch screen, so a 1200 × 1600 pixel image gives a page of about 318 × 423 mm. Margins still apply in this mode.
Why is the PDF so large?
The images are placed in the PDF at their full pixel size, so a few photos from a phone camera can produce a large file. Make the photos smaller with Image Resizer or Image Compressor before converting.
