How to Convert Images to PDF

To convert images to a PDF, add them in the order you want, choose a page size and save. Each image becomes one page. You can also go the other way and export each PDF page as an image.

Quick answer: images to PDF in 4 steps

1. Open JPG to PDF (or PNG to PDF for PNG files).
2. Add one or more images.
3. Drag them into the order you want and choose a page size.
4. Download the PDF.

Step by step in detail

1. Prepare your images

Crop and straighten photos before converting; it is easier to fix them as images. Name files in order (01.jpg, 02.jpg) so the default sort matches the page order you want. Phone photos are often very large; if the final PDF will be emailed, expect to compress it later.

2. Choose the page size

Option	Result
Match image size	Each page is exactly as large as its image
A4 or Letter	Images are scaled to fit standard paper, handy for printing
Margins	Add white space around the image for a cleaner printed page

Pick a standard size if the PDF will be printed or submitted to a portal, and match-image-size for photo albums or screenshots.

3. Set the order

Drag thumbnails up or down. Mixed orientations are fine; portrait and landscape pages can sit in the same PDF.

4. Convert and check

Download the PDF and scroll through it. Confirm the order, orientation and that nothing is cropped.

Supported image formats

Common inputs include JPG, PNG, WebP, BMP, TIFF, SVG and HEIC, each with its own tool, for example WebP to PDF, TIFF to PDF, HEIC to PDF and SVG to PDF. If you have a mix, Image to PDF accepts several formats in one go.

PDF to images

To turn pages back into pictures, use PDF to JPG or PDF to PNG.

	JPG	PNG
Best for	Photos	Text, diagrams, screenshots
File size	Smaller	Larger
Transparency	No	Yes
Edges and text	Slight softening	Sharp

Choosing resolution

Resolution is measured in DPI. 150 DPI is fine for viewing on screens. Use 300 DPI for printing or small text. Higher DPI means sharper images and larger files, so do not go higher than you need.

Scanned documents: make the text searchable

A PDF built from photos or scans is just pictures. You cannot search or copy its text. Run OCR PDF afterwards to add a text layer so you can search and copy the text. Straight, well-lit scans give the most accurate results, and OCR output should be proofread.

Typical use cases

• Receipts and expenses: photograph, convert, merge into one PDF per month.
• Signed forms: photograph a signed page, convert, then merge with the rest of the document.
• ID or document copies: convert to PDF and add a password before sharing.
• Design previews: export screenshots as a multi-page PDF.

Troubleshooting

• Photos are sideways. Rotate the images first, or fix pages with Rotate PDF.
• The PDF is huge. Photos from modern phones are large. Shrink the result with Compress PDF.
• An image will not load. The format may be unusual; convert it to JPG or PNG first, or use the matching format-specific tool.
• Pages look blurry. Start from the highest-quality source and avoid upscaling small images.

Privacy

Photos of documents often contain personal data. Converting in the browser keeps them on your device. You can check this with the airplane-mode test in Is it safe to use online PDF tools?
