Use this image to PDF converter to turn one or more JPG, PNG, or WebP files into a single PDF. Arrange the images, choose the page size, orientation, and margin, then download the result. Conversion runs in your browser, so your photos and scans are not uploaded. Each selected image becomes one PDF page. You can combine phone photos, screenshots, and scanned pages in a deliberate order instead of creating separate documents. **A4 and US Letter produce consistent printable pages**, while Match each image keeps each source aspect ratio and derives the PDF page from its pixel dimensions. JPG and WebP inputs are normalized as high-quality JPEG data, while PNG inputs keep transparency when the browser can decode them. The converter scales every image proportionally and never crops it. Processing and the finished download stay on your device. ## How to use it 1. **Add your images** - Drop JPG, PNG, or WebP files onto the converter, or click the drop area to choose them. You can add up to 40 images. 2. **Arrange the pages** - Drag image cards or use their arrow buttons to set the PDF page order. Remove any image you do not need. 3. **Choose the layout** - Pick A4, US Letter, or an image-matched page. Set automatic, portrait, or landscape orientation and choose a margin. 4. **Create and download** - Click Create PDF. When the local conversion finishes, download the combined document to your device. ## Who it's for - **Students** combining photographed notes or assignment pages into one ordered submission. - **Operations teams** bundling receipts, delivery photos, or signed forms into a shareable record. - **Designers and photographers** turning selected proofs or presentation boards into a predictable PDF sequence. - **Anyone scanning with a phone** arranging several page images before sending or archiving them. ## Expert note PDF uses points rather than pixels. Match each image interprets 96 pixels as one inch, then caps extremely large page dimensions for PDF compatibility. A4 or US Letter is the safer choice when the document will be printed on standard paper. ## Frequently asked questions ### Are my images uploaded to a server? No. Your browser reads the images and creates the PDF locally. CanDoYa does not receive the source files or the finished document. The page loads its PDF code as a static asset, but conversion does not send your images to a processing service. ### Is the image to PDF converter free? Yes. You can convert and download a PDF without payment, an account, or a watermark. The fixed safety limits are 40 images, 25 MB per source image, 100 MB combined, 40 megapixels per image, and 120 megapixels for the whole batch. ### Which image formats can I convert to PDF? The converter accepts JPG and JPEG photos, PNG graphics, and static WebP images that your browser can decode. Animated WebP files are treated as a single decoded frame. HEIC, TIFF, SVG, GIF, and camera RAW files are not accepted in this version. ### Can I combine multiple images into one PDF? Yes. Add several images and arrange them in the order you want. Each image becomes one PDF page, and the download contains the entire sequence. Use the arrow controls or drag the image cards before creating the document. ### Does converting JPG to PDF improve image quality? No. A PDF places the decoded image onto a page; it cannot restore detail that is missing from the source. The converter keeps the aspect ratio and avoids cropping. JPG and WebP inputs are normalized at high JPEG quality, so repeated lossy conversions should still be avoided. ### Should I choose A4, US Letter, or Match each image? Choose A4 for common international printing and US Letter for typical North American printing. Match each image creates a page with the source aspect ratio, based on 96 pixels per inch. It is useful for screen viewing, but standard paper sizes are easier to print predictably. ### Will transparent PNG areas stay transparent? PNG images are embedded as PNG data, so transparent pixels can remain transparent in the PDF. A PDF viewer may display those areas over white. JPG and WebP inputs are flattened onto white because JPEG does not support transparency. ### Why is there a limit on image size? Image decoding can use far more memory than the compressed file size. A 40 megapixel image needs roughly 160 MB just for one RGBA pixel buffer, before the browser holds previews and PDF data. The limits reduce tab crashes, especially on phones and memory-constrained laptops. ## Related tools - [Merge PDF Files](https://candoya.com/tools/merge-pdf/) - [Split PDF](https://candoya.com/tools/split-pdf/) - [Reorder PDF Pages](https://candoya.com/tools/reorder-pdf-pages/) - [PDF Page Counter](https://candoya.com/tools/pdf-page-counter/) - [PDF Watermark](https://candoya.com/tools/add-watermark-to-pdf/) --- *Markdown edition of , published for AI agents and other automated readers.
