Images to PDF

Converting images to PDF is a common need for document submission, government portals that require scanned documents, job applications that need attachments in PDF format, invoice and receipt collections that must be submitted as a single file, and photo archives that need a print-ready format. Rather than using desktop software or printing-then-scanning, this tool combines your JPG and PNG files into a PDF directly on your device using pdf-lib, with no upload and no account required.

How to use

1. Add your images. Drag multiple JPG or PNG files onto the drop zone or click to browse. Each image appears as a card in the file list with a thumbnail preview. You can add additional images after the initial upload without losing your current selection.
2. Reorder the pages. Drag the image cards to set the order they'll appear in the PDF. The first card becomes page 1, the second becomes page 2, and so on. Take time to get the order right, reordering after conversion means starting over.
3. Convert to PDF. Click Create PDF to assemble all images into a single PDF document. Each image is placed on its own page, sized to fit the page dimensions. Processing runs locally and completes quickly for typical document sets.
4. Download your PDF. The generated PDF downloads immediately. Open it in any PDF viewer to confirm the page order and image quality before submitting or sharing.

Tips for best results

• Ensure images are the same orientation. Mixing portrait and landscape images creates a PDF where pages alternate orientation, which can look inconsistent. Rotate landscape images to portrait (or vice versa) using a photo editor before uploading for a consistent document layout.
• Compress images before converting. Large image files produce large PDFs. If file size is important, many submission portals have a maximum file size limit, use the image compressor to reduce each image first, then convert to PDF.
• Consider merging PDFs after converting. If you already have some pages as PDFs and others as images, convert the images to PDF first, then use the PDF merger to combine everything into a single document.
• Check the final PDF page count. Before submitting, open the downloaded PDF and verify the page count matches your expected number. Scroll through all pages to confirm no images are missing or out of order.

Frequently asked questions

Is there a limit on the number of images I can convert?

No enforced limit. You can convert as many images as needed in a single session. Practical limits come from your browser's available memory, very large batches (50+ high-resolution images) may slow down processing but will complete. For extremely large collections, consider splitting into multiple PDFs and then using the PDF merger to combine them.

What image formats are accepted?

JPG and PNG files are accepted as input. WebP, HEIC, and other formats should be converted to JPG or PNG first using the image converter before creating the PDF. For HEIC files specifically (iPhone photos), use the HEIC to JPG converter first.

Why is my PDF so large?

Each image is embedded in the PDF at its full original resolution. A collection of ten 3 MB smartphone photos produces a PDF of approximately 30 MB. To reduce the PDF size, compress the images before converting, use the image compressor to bring each image down to a reasonable size (100–300 KB is often sufficient for document purposes) before creating the PDF.

Can I add text or annotations to the PDF?

This tool creates a simple PDF from images, each image becomes a full-page element in the document without additional text or annotation capability. For PDFs that need typed text, form fields, or annotations, a full-featured PDF editor (Adobe Acrobat, LibreOffice Draw, or a cloud PDF editor) would be required.

What page size does the PDF use?

Each page in the generated PDF is sized to match the dimensions of the corresponding image. If your images are different sizes, the PDF pages will have different dimensions. For a consistent page size (A4 or Letter), you would need to resize all images to the same dimensions before converting, using the image resizer to standardize dimensions first.

Can the resulting PDF be opened in any PDF reader?

Yes. The generated PDF follows the standard PDF format specification and can be opened in Adobe Acrobat, Preview on Mac, any browser's built-in PDF viewer, iOS and Android PDF apps, and any other standard PDF reader. No special software or plugins are required.
