Maybe you photographed a dozen pages of a signed agreement with your phone, or you have a folder of screenshots you need to send as one document instead of a dozen separate files. That's what Image to PDF is for: it takes your JPG and PNG files and stitches them into a single PDF, one image per page, in the order you pick them. If you're going the other direction — you already have a PDF and want individual page images out of it — you want PDF to Image, not this tool.
Step-by-step
- From the home page, open the Tools section (/en/#tools) and click the "Image to PDF" card.
- A modal opens with a drop zone that says "click or drag files to select" and a "Process now" button.
- Select your JPG or PNG images — you can pick several at once. The order they're read in becomes the page order, so rename files with a numeric prefix (01-, 02-…) first if sequence matters.
- Click "Process now". Everything runs locally: pdf-lib embeds each image onto its own PDF page, sizing that page to the image's exact native pixel dimensions rather than resizing it to A4 or Letter.
- Once every image has been embedded, your browser automatically downloads the result as images.pdf.
- Open images.pdf and check the page order, orientation, and that each image is fully visible — because page size always matches image size, a portrait photo next to a landscape one will produce noticeably different page shapes.
Common mistakes
- Mixing images with very different resolutions or aspect ratios — since each page's size matches its source image's pixel dimensions exactly, a high-resolution photo next to a small screenshot produces a PDF with wildly inconsistent page sizes; crop or resize images to a similar ratio first for a uniform document.
- Not controlling the selection order — pages come out in the order the images were selected, not sorted alphabetically by the tool, so prefix file names like 01-page.jpg, 02-page.jpg when order matters.
- Using formats other than JPG or PNG — anything that isn't detected as PNG is treated as JPEG, so HEIC photos straight off an iPhone, WEBP files, or other formats may not embed correctly; convert to JPG or PNG first.
- Expecting OCR or searchable text — a PDF built this way has no underlying text layer, so searching or copying its content isn't possible without a separate step.
- Forgetting to rotate sideways photos before uploading — the tool does not auto-rotate images, so a photo captured in landscape when you meant portrait is embedded exactly as captured.
FAQ
What image formats are supported for image to PDF?
JPG/JPEG and PNG. PNG files are detected by type and embedded as PNG; anything else is treated as a JPEG, so other formats like HEIC, WEBP, GIF or TIFF should be converted to JPG or PNG before uploading.
What page size does the exported PDF use?
Each page is sized to match its source image's exact pixel dimensions — there's no A4 or Letter normalization, so combining very differently sized images produces a PDF with different-sized pages.
Can I reorder pages after they've been combined?
Not within this tool. Control the order by selecting your images in the sequence you want before clicking Process now; renaming files with numeric prefixes is the simplest way to guarantee that order.
Will the resulting PDF have searchable text?
No. The output is strictly image-based — every page is a picture of your original file with no text layer, so it can't be searched or have its text copied.
Checklist
- Images renamed or ordered (01-, 02-…) to match the intended page sequence.
- All files are JPG or PNG, converted from other formats if needed.
- Images rotated and cropped correctly before uploading.
- Similar resolutions and aspect ratios used across images for a consistent look.
- The final images.pdf opened and every page checked for order and orientation.
- You're aware the result has no text layer and isn't searchable.
