How to scan documents into one PDF with your phone

Taking document photos that are easy to read

Most unreadable submissions come from the photo, not the conversion. A few habits make a big difference:

• Place the document flat on a dark table so its edges stand out.
• Use daylight from a window. Turn the flash off; it causes a bright glare on glossy marksheets and laminated cards.
• Hold the phone directly above the page, parallel to it, so the text is not slanted.
• Fill the frame with the page, keeping all four corners visible.
• Tap on the text to focus before taking the photo, and check it is sharp by zooming in.

Turning the photos into one PDF

Open JPG to PDF and add all the photos at once. Put them in the order the portal expects using the arrows, and tap rotate on any page that is sideways. Leave the page size on A4, the standard for Indian portals, and choose a small margin so the result looks like a scanned document.

Tap Convert and download. Each photo becomes one page, turned the right way up and scaled to fit.

Two-sided cards and colour documents

For two-sided documents such as Aadhaar, PAN or a driving licence, photograph the front and back separately and add both photos, front first. They become two pages of the same PDF, which most portals accept. If an application asks for both sides on a single page, follow its instructions.

Keep documents in colour. Certificates have coloured seals and stamps, and ID cards have photos, which can become unreadable or look suspicious in black and white.

Check it the way the reviewer will

Before uploading, open the PDF on your phone and zoom in on the smallest details: roll numbers, dates of birth, marks, signatures and seals. The person checking your application sees exactly this file. If a number is unclear to you, it will be unclear to them. Retake that page and replace it.

Combining with PDFs you already have

If some documents are already PDFs, such as a downloaded Aadhaar or a certificate from DigiLocker, convert your photos first, then join everything with Merge PDF. Put the files in the order requested in the application, often identity proof first, then education documents.

One file per document, or one file for everything?

Read the upload page before you build the PDF. Many portals have a separate slot for each document, such as one for the marksheet and one for the caste or income certificate. Those need one PDF per document, not a single combined file. If you already made one big PDF, Split PDF can take it apart again by page range.

Where an application asks for self-attested copies, sign each page before you upload it. You can sign the paper copy before photographing it, or add your signature to the finished PDF with Edit PDF.

Keeping the file size down

Phone photos are large, so a PDF of several pages can easily exceed an upload limit. If it does, run it through Compress PDF and choose Extreme, which is designed for documents made from photos. Check the result by zooming in on small print before uploading.

Name the file so it is not rejected

Some portals reject file names with spaces or special characters, and all of them are easier to manage with clear names. Rename the download to something like name-marksheet-class12.pdf before uploading.
