You need to send a signed form, a receipt, a doctor’s note or a few pages of a handwritten document, and the only scanner you have is your phone. Snapping photos is easy. Turning them into a PDF that looks like a real document, rather than a stack of crooked pictures of your kitchen table, takes a little more care.
The process is simple: crop, convert with the right page settings, check the order, then compress. Each step takes a minute and makes a visible difference.
Try it: JPG to PDFTurn photos, scans and screenshots (JPG, PNG, WebP and more) into a single PDF with the page size, orientation and margins you choose.
Open tool — freeTake better photos first
No tool can rescue a blurry, shadowed photo, so start here.
- Put the page on a contrasting, plain surface. White paper on a dark table is easy to crop; white paper on a white desk isn’t.
- Shoot from directly above. Tilted photos make the page look like a trapezoid, with text shrinking toward the top.
- Use even light. Daylight near a window is ideal. Turn the flash off to avoid a bright glare spot, and watch for your own shadow.
- Fill the frame, but leave a small border so you don’t clip the edges of the page.
- Tap to focus on the text and check the photo by zooming in before moving on.
Many phones have a document scanning mode built in (in the Notes app on iPhone, and in Google Drive on Android, among others) that straightens and crops automatically. If you have it and it works well, use it. The steps below are for when you already have ordinary photos.
Crop before you convert
This is the step that separates a professional-looking PDF from an amateur one. Every bit of table, carpet or fingers around the page ends up in the final document, and it makes the page content smaller when printed.
Open each photo in our image cropper and trim to the edges of the paper. Use free cropping rather than a fixed ratio, since documents rarely match social media shapes. You can rotate there too, so fix any sideways photos at the same time. Your phone’s built-in photo editor can do the same job if you prefer.
One limit to know: simple cropping cuts a rectangle. If the photo was taken at an angle, cropping won’t fix the perspective. Retaking the photo from directly above is usually quicker than trying to correct it.
Choosing page size, orientation and margins
Our JPG to PDF converter lets you pick the page size, orientation and margins. These settings decide whether the result looks like a document or a photo album.
| Setting | What to choose | Why |
|---|---|---|
| Page size | Letter in the US and Canada, A4 almost everywhere else | Prints at the expected size for the recipient |
| Orientation | Portrait for most documents; landscape orientation for wide tables or slides | Matches the shape of the original page |
| Margins | A small margin for documents; none for photos you want edge to edge | Margins keep content clear of printer edges |
For forms, letters and receipts, I’d use the local standard paper size with a small margin. The page then prints cleanly and looks consistent, even if your photos were slightly different shapes.
How to convert photos to a PDF step by step
- Get the images onto the device you’ll work on. If you’re on an iPhone and the files are HEIC, convert them to JPG first if the converter doesn’t accept them. Our guide on HEIC vs JPG explains the difference.
- Crop and rotate each image so only the page is visible and it’s upright.
- Rename files in order if there are several pages: 01, 02, 03. It makes the next step foolproof.
- Open the JPG to PDF converter and add all the images. JPG, PNG, WebP and other common formats work. Everything is processed in your browser, so the photos aren’t uploaded.
- Arrange the order. Make sure page 1 is first and nothing is duplicated.
- Choose page size, orientation and margins, using the table above.
- Create and download the PDF, then open it and flip through every page.
Compress after, not before
Phone cameras capture far more detail than a document needs. Ten photos can easily turn into a PDF too large for many email providers or upload forms.
The simplest fix is to compress the finished PDF with our PDF compressor. Since every page is already an image, re-encoding the pages at around 150 dpi usually shrinks the file a lot while keeping text readable on screen. Choose 200 dpi or more if the recipient will print the document or run text recognition on it. Our guide to reducing PDF file size covers the settings in more detail.
Why after? Compressing each photo separately and then converting means making the quality decision several times. Doing it once on the final PDF is quicker, and you can judge the result as the recipient will see it.
Common problems and quick fixes
- A page is sideways in the PDF. Rotate that photo and convert again, or rotate the page in the PDF afterwards.
- Pages are out of order. Rearrange them before converting, or reorder pages in the finished PDF with a page organizer.
- Text is hard to read. The photo was probably too dark or slightly blurred. Retake it in better light rather than compressing harder.
- The recipient needs searchable text. A PDF made from photos contains images only. Run OCR on it if they need to search or copy text.
- Gray, dull pages. Brighten the photos a little in your phone’s editor before converting. Increasing contrast slightly makes text pop.
The short routine
Shoot straight down in even light, crop tightly to the page, and convert with your local paper size and a small margin. Check the order, then compress the finished PDF to around 150 dpi for email. It’s five minutes of work, and the result looks like it came out of a real scanner.
Frequently asked questions
What page size should I use when converting photos to PDF?
Use Letter in the US and Canada and A4 in most other countries, so the document prints correctly for the recipient. If the PDF will only be viewed on screen, either size works.
How do I combine several photos into one PDF?
Add all the images to a JPG to PDF converter at once, arrange them in the order you want, and create a single PDF. Each photo becomes one page.
Why is my PDF from photos so large?
Modern phone cameras take very high-resolution images, and each one becomes a full page in the PDF. Compressing the finished PDF, or resizing the photos first, usually brings the size down a lot without hurting readability.
