Whether you're compiling photos into a portfolio, combining scanned receipts into a single document, or turning screenshots into a shareable PDF, the Image to PDF converter handles it all. Add as many images as you need — JPG, PNG, WEBP, GIF, BMP, TIFF — reorder them with drag-and-drop, and export a perfectly formatted PDF.

Technical Details

OneClickPDF uses the pdf-lib library to create the output PDF document. Each image is embedded as a full page using its native resolution. JPG images are embedded directly (they're natively supported in PDF). PNG images are decoded and re-encoded. WEBP and other formats are first drawn onto a canvas and exported as either JPG or PNG before embedding. The tool respects EXIF orientation data, so photos taken in portrait mode on phones will display correctly. Page sizes use standard dimensions (A4: 595x842 points, Letter: 612x792 points) with images scaled to fit while maintaining aspect ratio.

Frequently Asked Questions

What image formats are supported?
JPG/JPEG, PNG, WEBP, GIF (first frame), BMP, and TIFF. These cover virtually all common image formats you'll encounter.
Is there a limit on how many images I can combine?
No artificial limit. You can add as many images as your browser's memory allows. Most devices handle hundreds of images without issues.
Will the image quality be reduced?
No. Images are embedded at their original resolution. JPGs are embedded directly without re-compression. The output PDF preserves the full quality of your source images.
Can I set different page sizes for different images?
The current tool applies one page size setting to all pages. For different sizes, you can use the 'Fit to Image' option, which makes each page match its image's aspect ratio.
Can I reorder pages after adding images?
Yes. Use drag-and-drop to reorder images before converting. You can also remove individual images from the list.
