Application forms, receipts for expenses, ID copies, homework, signed contracts: sooner or later someone asks for them as a single PDF. If all you have is a phone, you can still produce a tidy document that looks scanned rather than snapped on a kitchen table.
The process has three parts: take good photos, turn them into a PDF in the right order, then fix orientation and size.
Take photos that look like scans
Most of the quality is decided before you touch any tool. A few habits make a big difference:
- Put the page on a dark, flat surface so its edges stand out.
- Use daylight or even room light and avoid the flash, which leaves a glare spot.
- Hold the phone directly above the page, parallel to it, so lines are not skewed.
- Fill the frame with the page and keep a thin border around it.
- Take one photo per page, in order, so they are already sorted.
Step by step: make the PDF
Trim the edges (optional)
If the photos show the table around the page, crop them with Crop Image first. A clean edge makes the PDF look far more professional.
Combine the images
Open JPG to PDF and add up to 20 photos. JPG, PNG, WebP, BMP and GIF all work, even mixed together.
Set the order and page size
Arrange the images in reading order. Choose A4 or US Letter if the PDF will be printed or uploaded to a form, and auto-detect orientation so landscape pages are not squeezed.
Create and check
Download the PDF and flip through it. If a page is sideways, fix it with Rotate PDF.
Fixing common problems
Most issues with phone scans come from the photo, not the conversion:
- Pages look grey or yellow: shoot near a window in daylight, because indoor bulbs tint white paper.
- Text is blurry: tap the screen on the text to focus before taking the photo, and hold the phone still.
- Pages are in the wrong order: reorder them in JPG to PDF before creating the file, or name the photos with numbers first.
- The PDF is sideways on screen: rotate the affected pages with Rotate PDF rather than retaking the photo.
Adding pages later
Forgot a page, or have a second batch from another day? Turn the new photos into their own PDF, then join both files with Merge PDF, setting the order before you merge. There is no need to start over.
Make it small enough to send
Phone cameras produce large photos, often 3 to 5 MB each, so a ten-page document can easily reach 40 MB. Run the finished file through Compress PDF with the Ebook preset. Photographed text stays readable while the file typically shrinks by 70 to 90 percent, usually enough for any email or upload form.
Privacy
Documents like IDs, bank letters and medical forms are sensitive. Cropping, JPG to PDF, Rotate and Merge all run in your browser, so the images are never uploaded. Compression is done on our server and the file is deleted as soon as the smaller version is sent back.
Frequently asked questions
Can I make the text in the PDF searchable?
Not with these tools. Photos contain pictures of text, and making them searchable needs OCR (optical character recognition). Google Drive can do this: upload the PDF and open it with Google Docs.
How many photos can I put in one PDF?
Up to 20 per batch in JPG to PDF. For more, create several PDFs and join them with Merge PDF.
Should I use A4 or Fit to image?
Use A4 or Letter for anything that might be printed or submitted to an official form. Fit to image is better for screenshots, photo albums and documents that will only be viewed on screen.
