JPG, PNG or WebP · each image becomes one PDF page

Turning photos into a PDF is the standard way to submit scanned documents. Most institutions — universities, immigration offices, banks, HR departments — ask for PDF rather than JPG because a single PDF holds multiple pages in order, prints predictably, and cannot be casually edited.

This tool combines JPG and PNG images into one PDF in your chosen order. Because the work happens in your browser, this tool is safe for documents you would never upload to a random website — contracts, payslips, medical records, bank statements, passport scans. Nothing is transmitted, so there is no server copy to be retained, indexed or breached.

How to use the Images to PDF

  1. Add your images

    Drag in JPG or PNG files, or click to browse. Select several at once — phone photos of documents work fine.

  2. Arrange the page order

    Drag the thumbnails so the pages appear in the order you want in the final document.

  3. Convert

    Each image becomes one page, sized to fit while keeping its aspect ratio so nothing is stretched.

  4. Download the PDF

    The finished document downloads straight to your device.

Getting a good scan with a phone camera

  • Use indirect natural light. Position the document near a window, not under a ceiling light that casts your own shadow across it.
  • Shoot straight down. Angled photos produce keystoned pages that look unprofessional and can fail automated document checks.
  • Use a plain contrasting background so the document edges are unambiguous.
  • Fill the frame with the page — cropping later loses resolution you could have captured.
  • Check focus before moving on. Blurred small print is the most common reason a submitted document is rejected.
  • Aim for around 200–300 DPI equivalent. Any modern phone camera exceeds this if the page fills the frame.

For a photographed page, JPG at high quality is the right choice. For a screenshot of a form or a document with sharp black text on white, PNG keeps the edges clean.

Meeting submission requirements

Institutions usually publish exact requirements, and the most common rejection reasons are avoidable:

  • File size limits — often 2 MB or 5 MB per document. Compress the images first with the image compressor if you exceed it.
  • Page order — put the pages in reading order before converting; a reviewer should not have to reassemble your document.
  • All four corners visible — many verification systems reject documents with a cropped edge.
  • Colour, not greyscale, is frequently required for identity documents so security features remain visible.
  • One document per PDF unless the instructions say otherwise.

Why PDF rather than sending images

A PDF fixes page order, prints at a predictable size regardless of the recipient’s software, opens identically on every platform, and keeps a multi-page document together as one unit. Emailing eight separate JPGs asks the recipient to do work you could have done once.

It also compresses more sensibly for documents and is the only format most institutional upload portals accept at all.

Frequently asked questions

Which image formats are supported?

JPG and PNG, the two formats phones and screenshots produce. Convert other formats first with the image converter.

Are my images uploaded to a server?

No. Conversion happens entirely in your browser and your images never leave your device.

Can I control the page order?

Yes. Drag the thumbnails into the order you want before converting — the PDF follows that sequence exactly.

Will the images be stretched or cropped?

No. Each image is scaled to fit the page while preserving its aspect ratio, so proportions are always maintained.

How do I reduce the PDF file size?

The PDF is roughly the sum of its images, so compress them first with the image compressor. Dropping JPG quality to around 70% typically halves the size with no visible difference on a document.

Can I mix portrait and landscape images?

Yes. Each page is sized to its own image, so a document can contain both orientations.

Does this work on a phone?

Yes, and it is often the easiest route — photograph the pages, then convert them in the mobile browser without installing a scanner app.

Will the text in my scans be searchable?

No. The pages are images, so there is no text layer. Searchable text requires OCR, which this tool does not perform.
