Converting images to PDF is useful whenever you need to bundle photos, scans, or screenshots into a single, shareable document. Whether you want to convert images to PDF for receipts, create a portfolio, compile scanned pages, or prepare a document for printing, the process is quick and preserves your original image quality.
Common use cases
- Receipts and invoices — photograph paper receipts with your phone and combine them into a single PDF for expense reports or tax filing.
- Document scanning — if you do not have a proper scanner, photographing pages and converting to PDF works well, especially for forms and letters.
- Portfolios and presentations — designers, photographers, and artists can compile their work into a polished PDF for sharing with clients.
- Multi-page submissions — some forms or applications require a single PDF upload. If you have separate image files, convert and combine them first.
- Archiving — PDFs are more organized and easier to manage than a folder full of loose image files.
Supported formats
The Images to PDF tool accepts JPEG and PNG files. JPEG is the most common format for photographs and phone camera images. PNG is typically used for screenshots, graphics with transparency, and images where you need lossless quality. You can mix both formats in a single conversion — some pages can be JPEG while others are PNG.
Image order matters
Each image becomes one page in the resulting PDF, in the order you arrange them. The tool lets you reorder images before converting, so you can arrange pages in the correct sequence. If you are converting scanned document pages, make sure they are in reading order. For a portfolio, arrange pieces in the order you want the viewer to see them.
Quality and page sizing
Images are embedded in the PDF at their original resolution — there is no recompression or quality loss during conversion. Each page in the PDF is sized to match the image dimensions, so you do not need to worry about cropping or stretching. A portrait phone photo will create a portrait page, and a landscape screenshot will create a landscape page.
If your images are very high resolution (such as photos from a modern camera at 4000+ pixels wide), the resulting PDF pages will be large. This is fine for viewing on screen, and the PDF will print at excellent quality.
Limits
- Up to 20 images per conversion. If you have more, convert in batches and then merge the resulting PDFs.
- 50 MB total across all images combined.
- Individual images can be up to 50 MB each (within the total limit).
After conversion
Once your images are combined into a PDF, you have several options for further processing. If the file is too large, use the Compress tool to reduce its size — image-heavy PDFs typically compress very well. If the resulting document contains text (scanned pages), you can run OCR on it to make the text searchable and copyable.
Tips for best results
- Clean up photos first — if you are photographing documents, make sure the lighting is even and the page fills the frame. Crop out backgrounds before converting.
- Use consistent orientation — rotate images to the correct orientation before uploading. While you can rotate pages after conversion using the Rotate tool, getting it right from the start saves a step.
- Name files in order — if your files are named sequentially (001.jpg, 002.jpg, etc.), they will likely upload in the correct order automatically.
