Image to PDF Converter: JPG and PNG to PDF Online

How to convert images to PDF

1. Click the upload box or drag photos onto it. You can add JPG, PNG, WebP, GIF and BMP images, and add more later.
2. Check the page numbers and use the ← and → buttons to change the order, or × to remove an image.
3. Pick the Page size (A4 is the default), the Margin and the Image quality.
4. Click Convert to PDF. The file downloads as images_to_pdf.pdf, or with the image's own name if you converted a single picture.

How the images are placed on the page

Each image gets its own page. The tool fits the image inside the margins without stretching it and centres it. A landscape photo on A4 or Letter gets a landscape page so it is not shrunk.

Formula: with page width W, page height H and margin m, the usable box is (W − 2m) × (H − 2m). The image width is set to the box width; if the resulting height is too tall, the height is set to the box height instead and the width follows from the aspect ratio.

Worked example: a 3000 × 4000 px phone photo of handwritten UPSC Mains notes on A4 with a 10 mm margin. The box is 190 × 277 mm. Width 190 mm would need a height of 253.3 mm, which fits, so the photo is printed at 190 × 253.3 mm and centred with about 21.8 mm of space above and below.

Tips for scanned notes and certificates

• Shoot in daylight, from straight above. Shadows and tilted angles make text hard to read in the PDF.
• Crop before converting. Remove table edges and fingers so the page area is used for the document.
• Check the size limit. Application portals often cap PDF uploads; if yours does, use Smaller file, or compress the images first. Check your notification for the exact limit.
• Need to combine with an existing PDF? Make this PDF, then join them with Merge PDF.

Frequently Asked Questions

How do I convert multiple images into one PDF?

Add all the images, put them in order with the arrow buttons, and click Convert to PDF. Each image becomes one page of a single PDF, in the order shown by the page numbers.

How do I convert a JPG to PDF on my phone?

Open this page in Chrome or Safari, tap the upload box, pick photos from your gallery, then tap Convert to PDF. The PDF is saved to your Downloads folder; nothing is uploaded.

Why was my phone photo sideways in other converters?

Phones store photos with an orientation tag instead of rotating the pixels, and some PDF tools ignore it. This tool redraws each photo in your browser first, so pages come out the right way up.

How can I make the PDF smaller?

Choose Smaller file under Image quality, which limits each image to 1600 pixels on the long side and uses stronger JPEG compression. For a strict KB limit, compress the images first with the Image Compressor.

Which page size should I use?

Use A4 for Indian forms, printing and college submissions, Letter for US documents, and Fit page to image when you want no white space, such as for long screenshots.

Are my images uploaded to a server?

No. The PDF is created inside your browser with the jsPDF library, so your photos and documents never leave your device.
