About JPG To PDF

JPG To PDF turns one or many JPG/JPEG photos into a single, share-ready PDF document, placing one image on each page in the exact order you selected them. Everything runs inside your web browser using the Canvas API and the pdf-lib library, so your pictures are never uploaded to a server. There is no queue, no watermark, and no file-size account gate — you can convert a single snapshot or dozens of holiday photos and the images stay on your own device the whole time.

What sets this converter apart from a fixed-size image-to-PDF tool is control over the page geometry. You choose the page size, the orientation, and the margin, and the PDF is rebuilt instantly every time you change an option or add and remove images:

- Page size: A4 (595 × 842 pt, which is 210 × 297 mm), US Letter (612 × 792 pt, which is 8.5 × 11 in), or Fit to image, where each page is created at the exact pixel dimensions of the photo so it fills the page edge to edge with no borders. - Orientation: Auto, which picks portrait or landscape to match each individual image's shape (wide photos get landscape pages, tall photos get portrait pages); or force every page to Portrait or Landscape for a uniform document. - Margin: None, Small (18 pt), or Normal (36 pt) of white space around each image, useful when the PDF will be printed and you want a clean border or room for a binding.

JPG (also written JPEG) is the format most cameras and phones save photos in because its lossy compression keeps continuous-tone images — skies, skin, landscapes — small while preserving detail. That makes it the natural source for photo-heavy PDFs: portfolios, receipts, ID scans, contact sheets, and printable albums. Because each image becomes its own page, the resulting PDF is easy to page through, print, email, or archive as a single file instead of a folder full of loose pictures.

Under the hood, every image is first decoded and redrawn onto a white canvas background and re-encoded as a clean baseline JPEG. This step quietly fixes files that would otherwise trip up a PDF writer: progressive JPEGs, CMYK-color JPEGs from print workflows, images with unusual metadata, and transparent source images (whose empty areas are flattened to white instead of turning black). The normalized JPEG is then embedded directly into the PDF, so the picture data is stored efficiently rather than re-compressed a second time, and each page is sized according to the option you chose. The image is scaled to fit inside the page's printable area while preserving its aspect ratio and is centered both horizontally and vertically. Small images are never blown up past their native resolution, so a low-resolution photo stays crisp instead of turning blurry.

Because the whole conversion is client-side, it is fast and completely private: sensitive documents such as passports, tax paperwork, or signed forms never leave your computer, which matters for anyone handling confidential material. Reordering is simple — the pages follow your selection order, and you can remove any image or clear the whole set and start over. When you are done, the tool reports the page count and final file size and gives you a direct download link. If you only need a plain letter-sized conversion, the companion image-to-PDF tool covers that; use JPG To PDF whenever you want to choose the paper size, orientation, or margins for your photos.

Frequently asked questions

Are my photos uploaded to a server?
No. JPG To PDF runs entirely in your browser using the Canvas API and pdf-lib. Your images are read, converted, and saved locally, so nothing ever leaves your device — which keeps sensitive documents like IDs and receipts private.
What is the difference between A4, US Letter, and Fit to image?
A4 pages are 595 × 842 pt (210 × 297 mm), the international standard. US Letter pages are 612 × 792 pt (8.5 × 11 in), common in North America. Fit to image makes each page the exact size of the photo so it fills the page edge to edge with no borders.
Can I put many images into one PDF?
Yes. Select as many JPGs as you like and each becomes its own page, one image per page, in your selection order. You can add more, remove individual pages, or clear all and start again; the PDF updates automatically.
