How to Convert JPG to PDF
- Select one or more images.
- Arrange the images in the page order you want.
- Choose page size, orientation, margins and image quality.
- Click Convert to PDF.
- Download the validated PDF.
Convert Multiple JPG Images to One PDF
Each selected image becomes one PDF page. Reordering the cards changes the final page sequence, and keyboard Move Up and Move Down controls provide an alternative to drag-and-drop.
Choose PDF Page Size
Fit to image keeps a page ratio based on each source image. A4, Letter and Legal use standard paper dimensions. The Contain option keeps the whole image visible, while Fill can crop the edges to fill the page.
Portrait vs Landscape
Auto chooses the orientation that best matches each image when a fixed paper size is used. You can also force portrait or landscape for a consistent document.
How Image Quality Affects PDF Size
High quality retains more photographic detail but usually creates a larger PDF. Recommended is a practical default. Smaller file uses stronger JPEG recompression and may soften fine detail.
JPG vs PNG
JPG is efficient for photographs. PNG is useful for graphics and transparency. For PDF output, transparent regions are placed on a white page so they do not become black.
Phone Photos and Orientation
The browser image decoder is asked to respect encoded image orientation, including common phone-camera EXIF orientation. You can also rotate individual images before conversion.
Privacy
The source images are decoded and converted locally. The tool does not send filenames or image bytes to a conversion API.
Troubleshooting
If an image cannot be decoded, remove it and try a valid JPG, PNG or WebP file. Very large images are rendered within a bounded canvas to reduce mobile memory failures.
Convert Several Photos Into One Ordered PDF
When multiple images are selected, each image becomes one PDF page and the displayed card order becomes the final PDF page order. You can add more images after the first selection, remove individual files, rotate an image, drag cards into a new order, or use the keyboard-friendly Move Up and Move Down actions. This is useful when phone photos, scanned receipts or assignment pages were captured out of sequence. The converter uses the final visible order at conversion time rather than the original file-picker order.
Fit to Image, A4, Letter and Legal
Fit to image creates a PDF page based on the image's own aspect ratio. Fixed paper sizes such as A4, Letter and Legal are better when a predictable printable page is required. With fixed paper, the image is scaled into the printable area according to the selected margins. Auto orientation chooses portrait or landscape from the image, while manual orientation lets every generated page use the selected direction. The converter never deliberately stretches an image out of proportion.
Contain Versus Fill
The default Contain option keeps the complete image visible. Depending on the source and paper aspect ratios, this can leave white space around the image. Fill uses the available page area more aggressively and may crop edges to avoid empty space. Contain is safer for documents, screenshots and scanned forms because important content is less likely to be cut off. Fill is often more suitable for decorative photographs where edge cropping is acceptable.
Phone Photos and Image Orientation
JPEG photos from phones can store camera orientation as metadata instead of physically rotating the pixel array. The browser image decoder is asked to honor this orientation when available, and the converter also provides a manual rotate control. Previewing the card before conversion is useful for checking portrait photos. If a very unusual browser or image file ignores its embedded orientation, use the rotate button so the visible card matches the page you want.
PNG and WebP Transparency
PDF pages need a predictable background when transparent images are rasterized. This converter composites transparent PNG and WebP content on white before embedding it, preventing transparent areas from unexpectedly becoming black. The original image itself is not modified on disk. The generated PDF contains the browser-rendered appearance for that page.
Image Quality and PDF Size
High quality uses a higher JPEG quality setting when a page must be re-encoded. Recommended is a balanced default for everyday photos and documents. Smaller file uses more compression and can reduce fine photographic detail. Exact PDF size depends on image dimensions, visual complexity and how efficiently the source was already compressed, so the page does not invent a fixed percentage saving. For text screenshots and diagrams, inspect small lettering after using the smaller-file option.
Large Images and Browser Memory
Modern phone cameras can create very large images. Rather than keeping full-resolution copies of every rendered page indefinitely, the converter works through images sequentially and uses bounded canvas dimensions. This reduces the chance that a set of high-megapixel photos exhausts mobile browser memory. Extremely large batches can still be demanding, so a desktop browser may be more practical for dozens of high-resolution source images.
Common JPG to PDF Workflows
Typical uses include combining photographed homework pages, assembling identity or application documents, grouping receipts, turning product photos into a shareable document, collecting signed pages, and creating a simple photo report. A sensible workflow is to put the images in final order first, rotate any sideways items, choose paper and margins, convert, then open the downloaded PDF and inspect the first and last pages before sharing it.
Frequently Asked Questions
Can I combine several JPGs into one PDF?
Yes. Each image becomes a page in the displayed order.
Can I use PNG or WebP?
Yes, when the current browser can decode those formats.
Can I change page order?
Yes. Drag the cards or use the Move Up and Move Down buttons.
Will transparent PNG areas stay transparent?
The PDF page uses a white background, so transparent areas become white.
Are images uploaded?
No. The browser decodes and converts them locally.
Does rotation affect the final PDF?
Yes. The selected 90-degree rotations are applied to the PDF page image.
What is Fit to image?
It creates a PDF page with the same visible aspect ratio as the source image.
Why is the PDF large?
High-resolution photos and the High quality setting can create larger files. Try Recommended or Smaller file.
