Phone Photos to PDF: Sideways Pages, Huge Files, No Search

You photographed eight pages of a lease on the kitchen table, turned them into a PDF, and now page three is lying on its side, the file is too big to email, and nobody can search it. Most of that gets decided before you tap the shutter.

Shoot it like a scan

• Lay the page flat on a plain, darker surface so its edges stand out.
• Use soft light from the side, like a window next to you. A ceiling light directly overhead puts the shadow of your phone and hand right on the text.
• Turn the flash off. It leaves a bright hot spot in the middle of the page and glare on anything glossy.
• Hold the phone flat above the page, not tilted. An angled shot shrinks the lines at the far end, which hurts text recognition later.
• Fill the frame with the page, then crop to its edges before converting. The tool uses the whole photo as the page, tabletop and all.

Why a page comes out sideways

Phones often save the picture in whatever way the camera sensor sits and attach a small orientation tag that says “show this rotated.” Your gallery app reads the tag, so the photo looks upright there. Our JPG to PDF tool places the image exactly as it's stored and doesn't apply that tag, which is how a photo that looked fine on your phone ends up on its side in the PDF.

1. If every page turned the same way, run the finished PDF through Rotate PDF once. It rotates all pages by 90, 180, or 270 degrees in one go.
2. If only a few pages are off, split them out, rotate that part, and merge the pieces back together.

Easier still: hold the phone the same way for every shot, and a single rotate fixes the lot.

Why the file is so big

A 12-megapixel photo is roughly 4000 by 3000 pixels and usually a few megabytes. The tool doesn't shrink your photos, so twenty pages add up quickly, even though an A4 page scanned at 300 dpi is only about 2500 by 3500 pixels.

Here's the catch. Our Compress tool mostly saves space by lowering the resolution of images that are packed more densely than their page needs. JPG to PDF sizes each page to match its photo, so from the compressor's point of view there's little to trim, and you'll often see almost no change. The real fix happens before you convert:

• If your camera app offers a lower resolution, pick it for documents. Around 8 megapixels is still plenty for printed text.
• Skip the 48-megapixel and RAW modes for documents.
• Crop tightly. Every pixel of tabletop around the page adds to the file size too.

Compress does earn its keep on PDFs from a phone's built-in document scanner, like the one in the iPhone Notes app. Those put high-resolution images on normal page sizes, which is exactly what it knows how to shrink.

Getting the pages in order

Pages follow the order of the file list on the tool page. Phones number photos in sequence, like IMG_4512 then IMG_4513, so the Sort by Name button usually gives you shooting order. Two traps: the counter rolls over from 9999 back to 0001, which sends your last pages to the front. And names such as page_2 and page_10 sort character by character, so page_10 lands ahead of page_2. In either case, use the up and down arrows next to each file.

Already made the PDF and spotted a page out of place? Organize PDF takes a new order like 3,1,2 and rebuilds the file to match.

Making the text searchable

A PDF of photos is still just pictures of words. OCR PDF reads the text and adds an invisible layer behind each page, so you can search and copy while the page looks the same as before. It reads English only and expects upright pages. It won't turn a sideways page for you, and a sideways page usually gives back little or no text, so rotate first.

Common questions

My iPhone photos are HEIC. Will they work?

No, this tool only takes JPG files. To make the camera save JPEGs from now on, go to Settings → Camera → Formats and choose Most Compatible. Photos you've already taken as HEIC need converting to JPG first.

Will the PDF print on A4 or Letter paper?

The pages aren't A4 or Letter sized. Each one takes the shape and dimensions of its photo, which works out much larger than a sheet of paper. Pick “Fit to page” or “Scale to fit” in your print dialog and each page shrinks to fit the paper.
