Image to PDF Converter
Put several pictures into a single PDF in the order you choose. Pick the paper size, add margins, and optionally keep the file under a size limit for an upload form. Nothing leaves your device.
🔒 Runs in your browser. Your files and text are not uploaded.
How to use the Image to PDF
- Drop your pictures on the box, or click it to choose files. You can add up to 60 images, and add more later.
- Put the pages in order with the ↑ and ↓ buttons, and remove any with ×.
- Choose a Page size (A4, US Letter, US Legal, A5 or “Same as each image”), the orientation and the margin.
- Choose the image resolution. Optionally type a size limit under “Limit PDF size (KB)”.
- Press “Create PDF” and download the file.
Page size, orientation and margins
A4 (210 × 297 mm) is the standard in most of the world; US Letter (8.5 × 11 in) is used in the United States and Canada. Choose the one the recipient will print on, or “Same as each image” to make every page exactly as large as its picture, a good choice for screenshots and when nobody will print the file. Orientation “Automatic” picks portrait or landscape for each page to suit the picture. A margin of 10 or 20 mm leaves a clean white border, which is useful for documents that will be hole-punched or stamped; “None” fills the whole page.
Resolution and file size
| Setting | Pixels on the long side | Good for |
|---|---|---|
| High (recommended) | Up to 2400 | Photos and scans that may be printed; about 200 dpi on A4 |
| Medium | Up to 1600 | Documents for email; about 135 dpi on A4 |
| Small | Up to 1000 | Reading on screen; text gets soft if printed |
| Original | No change | JPEG files are embedded byte for byte without recompression |
If an upload form limits the PDF to a number of kilobytes, type it under “Limit PDF size”. The tool lowers the JPEG quality, and then the image size, in steps until the PDF fits, and tells you what it did. If it still cannot fit, it says so, and you can remove pages or use smaller pictures.
Scans and photos of documents
A good PDF starts with a good picture. Photograph each page in daylight from directly above, with the page filling the frame, or use a scanner app. If a picture is crooked, straighten it with the Rotate tool and trim the edges with the crop tool before you put it into the PDF. Keep black text on white paper, because it compresses far better than a coloured or shadowed page. Put the pages in order in the list and check the thumbnails before you press the button.
How the PDF is built, and its limits
Each picture becomes one page. JPEG pictures are stored directly, as PDF supports JPEG natively; other formats such as PNG, WebP, GIF and BMP are drawn on a white background and stored as JPEG at the quality you choose, so transparent areas turn white. The PDF is created in your browser with no watermark and no tracking.
The pages are pictures: the text on them is not selectable or searchable, because no text recognition (OCR) is performed. If you need searchable text, use an OCR program on the original scan. For single-format shortcuts, see JPG to PDF and PNG to PDF.
Frequently asked questions
How do I combine several pictures into one PDF?
Drop all of them on the box, arrange them with the arrow buttons, choose the page size and press Create PDF. The pages appear in the order of the list.
How do I make the PDF smaller?
Choose a lower resolution, reduce the JPEG quality, or type a limit under “Limit PDF size (KB)”. The tool then shrinks the images until the PDF fits.
Will my pictures be recompressed?
Only when you ask for it. With the resolution set to “Original”, healthy JPEG files are embedded unchanged. Other formats are converted to JPEG.
Is there a page limit?
You can add up to 60 images at a time. Very large pictures use more memory, so use a smaller resolution on a phone.
Are my files uploaded?
No. The PDF is created in your browser, and the pictures never leave your device.
