JPG to PDF — Photos into One Document
Drop a set of JPGs and get a PDF. The usual reason is a phone camera: you photographed a form, a receipt book, a passport page or a signed contract, and whoever wants it will only accept a single PDF. Drag the rows into the right order, pick a paper size, and the images are embedded as-is — no re-compression, so a photo does not lose a second generation of quality on the way in.

Getting the order right
This is the part that goes wrong. When you select a folder of photos, the operating system hands them
over in its order — usually alphabetical by filename — which is not the order you clicked
them in and not necessarily the order you took them in. IMG_9.jpg sorts after
IMG_10.jpg in a plain alphabetical sort, so page 9 lands after page 10.
So the rows are draggable, and each shows a thumbnail. Check them against the document before converting; it takes five seconds and saves sending a contract with its pages shuffled. Row 1 becomes page 1.
Page size, or no page at all
A photo has an aspect ratio; a sheet of A4 has a different one. Something has to give, and you choose which:
- A4 or US Letter puts each photo on a standard sheet, scaled to fit inside the margin. This is what you want for anything that will be printed or filed, and what most institutions expect. Portrait photos fit naturally; a landscape photo leaves white bands above and below.
- Fit to image makes each page exactly the shape of its photo, with no margin and no white space. Best for screenshots, artwork, or a comic — and for keeping the file as small as possible. The pages will be different sizes if the photos are.
- Landscape orientation is worth switching to if every photo is wider than tall; otherwise you are paying for white space on every page.
Photographing a document so the PDF is usable
The conversion cannot rescue a bad photo, and most rejected scans fail for the same few reasons.
- Fill the frame with the page, straight on. A photo taken at an angle produces a trapezoid that no amount of cropping straightens.
- Diffuse light, no flash. Flash gives a blown-out hotspot in the middle; a window and a shadow-free table give an even page.
- Check focus on the smallest text before you move on to the next page. Phone cameras habitually focus on the table edge instead.
- Rotate the images first if your phone saved them sideways — or fix it afterwards with Rotate pages.
- Then run OCR if the recipient needs to search or copy the text. A photo in a PDF is a picture; OCR adds the invisible text layer that makes it a document.
How to convert JPG images to a PDF
- Drop your JPGs — or PNGs, both work. They appear as rows with thumbnails.
- Drag the rows into the right order and remove any you did not mean to include. Row 1 is page 1.
- Choose the page size — A4 or Letter for something to be printed or filed, "fit to image" for screenshots and artwork.
- Set the margin, or drop it to 0 to use the whole sheet.
- Leave "one combined PDF" ticked for a single multi-page document, or untick it to get one PDF per photo.
- Click Convert to PDF and open the result to confirm the page order before you send it.
FAQ
How do I combine several JPGs into one multi-page PDF?
Drop them all in, put the rows in order, and leave "one combined PDF" ticked. You get a single file with one page per image, in row order.
Will the photos lose quality?
No. JPG data is embedded into the PDF byte for byte — there is no decode-and-re-encode step, so there is no second generation of JPG loss. The pages are only scaled geometrically, which does not touch the pixels.
The PDF is enormous. How do I shrink it?
Phone photos are 3–8 MB each, so ten of them make a 50 MB PDF. Run the result through Compress to a target size if there is a limit to hit, or Compress PDF for a general reduction. Choosing "fit to image" also helps a little by removing the padding.
Can I convert HEIC photos from an iPhone?
Not directly — HEIC support in browsers is inconsistent. Convert them to JPG first (jpgtoolkit.org does it in the browser too), or set your iPhone's camera to "Most Compatible" so it saves JPG in the first place.
My photos came out sideways in the PDF.
The image carries an EXIF orientation flag that says "rotate me", and not every pipeline honours it. Fix the result with Rotate pages, or rotate the JPGs before dropping them in.
Is there a limit on how many images?
No fixed limit — no upload, so no quota. In practice the file list with thumbnails gets heavy past about fifty images, and the whole PDF has to fit in your tab's memory.
Are my photos uploaded?
Never. The PDF is assembled in your browser with pdf-lib. Worth knowing when the photos are of a passport or a signed contract. See the privacy policy.
