How to Convert Images to PDF (JPG, PNG and WebP)
Want to convert images to PDF? You can combine photos, screenshots and scans into one tidy file in your browser. This guide covers the steps and the settings that matter.
Use our free Image to PDF tool to do this in just a few clicks. It runs in your browser, so your files stay private.
Key takeaways
- Each image becomes one page, in the order you choose.
- A4 or Letter pages suit printing. Same size as image suits viewing.
- Lower the quality or resize big photos to keep the PDF small.
- Your images stay in your browser.
When to convert images to PDF
A PDF opens on practically every device and keeps pages in a fixed order, so it is ideal for sending several images as one file. Typical cases are receipts, scanned documents, portfolios and forms that accept only PDF.
How to do it
- Open Image to PDF, or WebP to PDF if your files are WebP.
- Add your images and arrange them with the Up and Down buttons.
- Choose page size, orientation, margin and quality.
- Press Create PDF and download the file.
Choosing page size and orientation
| Choice | Best for |
|---|---|
| A4 | Printing and sharing in most countries |
| US Letter | Printing in the United States and Canada |
| Same size as image | Viewing on screen without white borders |
| Automatic orientation | Mixed portrait and landscape images |
Keeping the PDF small
Large photos make large PDFs. Shrink them with Resize Image, or lower the quality to 70 or 80%. For more ideas, read how to reduce image file size.
Images vs searchable text
A PDF made from images shows pictures of pages, so the text cannot be searched or copied. If you need searchable text, you will need OCR software after creating the PDF.
Turning a PDF back into images
To save PDF pages as pictures, use PDF to JPG or PDF to WebP. You can choose pages and resolution, and download all pages as a ZIP.
Tips for clean pages
- Take photos of documents in good light and from straight above.
- Crop away the background with the Crop Image tool.
- Keep all pages the same orientation for a tidy result.
- Name your files in order, such as page-1 and page-2, so they are easy to arrange.
Creating a PDF on a phone
The tools work in a mobile browser too. Choose photos from your gallery, arrange them, and download the PDF to your phone. Large camera photos make large PDFs, so lower the quality or resize them first if you plan to email the file.
Keeping documents private
Documents often contain personal details. Because AllWebP builds the PDF in your browser, your pages are not uploaded to a server. Close the tab when you are done, and delete the downloaded file if you no longer need it.
Order and naming
Pages follow the order of the list in the tool. Name your files in sequence, such as page-1 and page-2, before you add them, and you will rarely need to rearrange. You can still move any file up or down before you create the PDF.
Example: a bundle of receipts
Say you have six phone photos of receipts. Crop each one to remove the table, resize them so none is bigger than needed, add them in date order, choose A4 and a small margin, and create the PDF. You end up with one tidy file that is easy to email.
Quality and file size
| Quality | Effect on the PDF |
|---|---|
| 90 to 100% | Sharpest pages, larger file |
| 80% | A good balance for photos |
| 60 to 70% | Smaller file, softer text in photos |
Limits to know
- Up to 30 images per PDF, each up to 25 MB.
- Each image becomes one page.
- Pages are pictures, so the text is not searchable.
- Transparent areas are filled with white.
Troubleshooting
| Problem | Fix |
|---|---|
| An image will not load | It may be damaged or in an unsupported format, so convert it to JPG first |
| The PDF is too large | Lower the quality or resize the images |
| A page looks stretched | Pick the page size Same size as image, or crop first |
Common use cases
- Receipts and expense reports.
- Scanned forms and signed pages.
- Portfolios and design samples.
- Lesson handouts made from screenshots.
PDF or a ZIP of images?
A PDF keeps pages in order and opens everywhere, which makes it best for reading and printing. A ZIP of images is better if the recipient needs to edit or reuse each picture. Use Image to PDF for the first and the ZIP download of any converter for the second.
Accessibility note
A PDF made from images cannot be read by screen readers, because it contains pictures and not text. If accessibility matters, supply the text separately, or create the PDF from the original text document instead.
Printing the PDF
Choose A4 or Letter to match your paper, keep a small margin so nothing is cut off, and use a quality of 90% or more for sharp prints. Check the first page before you print the whole file.
