How do I convert images to a PDF?
Add one or more JPG, PNG or WebP images above and arrange them in order with the ↑ ↓ buttons. Choose the page size (A4, Letter, Legal or fit to image), margins and orientation, then press Create PDF. The tool will convert images to PDF in one file, with an optional KB limit for upload portals. Everything is built in your browser.
When do you need to turn photos into a PDF?
Many portals accept only PDF for documents, but people often have photos of their papers. Typical situations:
- Certificates photographed on a phone that must be uploaded as one PDF.
- Front and back of an ID card (Aadhaar, PAN, licence) on one or two pages.
- Handwritten assignments submitted to online classrooms.
- Receipts and bills for reimbursement claims.
- Multi-page forms filled by hand, signed and photographed.

Steps to make one PDF from images
- 1Add images
Select several at once, drag them in, or paste screenshots. Add more at any time.
- 2Put them in order
Use ↑ ↓ to reorder and ✕ to remove. Page 1 is at the top.
- 3Choose page size and KB limit
A4 with a small margin looks like a scanned document. Turn on the KB limit for portals, for example 200KB.
- 4Create and download
Open the PDF to check the order and readability.
Tips for document photos that look like scans
- Shoot from directly above with the document flat, in daylight, without flash.
- Crop away the table and background first with Crop and Resize Image.
- Use grayscale for text-only papers. It is smaller and often easier to read.
- Keep one document per PDF unless the portal asks for a combined file.
- Name the file clearly, for example "12th-marksheet.pdf", before uploading.
Is it safe to convert ID documents here?
Yes. The PDF is created on your own device with the open-source pdf-lib library. Your images are not uploaded, stored or seen by anyone. This matters for documents like Aadhaar. You can also mask Aadhaar numbers using the masked download option on the myAadhaar portal when full numbers are not required.
