PDF Merge
Combine multiple PDF files into a single document in the order you choose.
Open tool →Image to PDF Converter
Select one or more photos or scans and this tool lays each one out on its own page of a new PDF, in the order you add them. Nothing is uploaded; the conversion happens on your device.

Understand image size and page size
The converter uses image width and height as PDF page dimensions in points. It embeds each image as a page without OCR. A pixel count is not a promise of a particular print size or resolution.
| Input or check | Expected result or decision |
|---|---|
| A 480 × 360-pixel PNG | One landscape page measuring 480 × 360 PDF points. |
| A 180 × 220-pixel WebP | One portrait page measuring 180 × 220 PDF points after browser decoding. |
| Mixed image dimensions | Different page sizes; resize and rotate sources first when consistency matters. |
Try the 480 × 360-pixel test PNG. Open the downloaded PDF and check its one landscape page.
How it works
- Choose or drag in your JPG, PNG, or WebP images. Use Move up, Move down, or Remove to set the page order.
- Each image becomes one page in the resulting PDF, sized to match the image.
- Click convert to build and download the finished PDF.
Common uses
- Turning phone photos of a signed document into a single PDF to email.
- Bundling receipt photos into one file for an expense report.
- Creating a simple PDF portfolio from a set of images.

Prepare images for a document
PNG, JPEG and WebP images can become separate PDF pages. Each page uses the image dimensions. For consistent page sizes, resize the source images first. Very large images can exceed your browser memory.
A practical walkthrough
- Select photographs of a multi-page document in reading order and convert them into a single PDF.
- Check that every page is upright and that small text remains readable at normal zoom.
- Use the conversion button to download the PDF, then open it and inspect every image page.
Tips for a reliable result
This creates image-based pages, not searchable OCR text. Crop and rotate your source images first for a cleaner document.
What to use next

Open tool →How this tool handles your data
Selected images are assembled into a PDF in your browser and are not sent to an Anvil conversion server.
Known limitations
The PDF contains image pages rather than OCR text. Page size follows image dimensions, and large batches can exceed browser memory or create large downloads.

Questions and troubleshooting
What image formats are supported?
JPG, PNG, and WebP. If your browser cannot decode an image, export a working copy as PNG or JPEG and retry.
Can I control the page order?
Yes. Use Move up, Move down, or Remove in the selected-image list before converting. Each remaining image becomes one PDF page in that order.
Will the images be resized?
Each page is sized to match its image, so nothing is cropped or stretched.
When an image cannot be converted
Open the source in an image viewer, then export a working copy as PNG or JPEG if the browser cannot decode its format. Retry with smaller images if memory is limited. Use Move up and Move down to arrange the selected images before converting. Crop and rotate source images in an image editor first.
Why does the PDF contain large or differently sized pages?
Pages follow the dimensions of the source images. Prepare consistently sized, upright images first if the final document needs a uniform appearance.
Does the converter recognize handwriting?
No. It places images into PDF pages without recognizing text. Keep the images readable and use a separate OCR workflow if searchable text is required.
