Convert images to PDF. Rearrange, rotate, choose page size, margins & orientation.
Combine photographs and scans into a single PDF, with control over page order, page size, orientation and margins. The standard way to turn phone photos of a document into something a portal will accept.
Most application portals want a multi-page document as one PDF rather than a folder of JPEGs. This tool takes your images, places each one on a page, and assembles them into a single file in the order you specify.
| Setting | Recommended | Why |
|---|---|---|
| Page size | A4 (Letter in North America) | Prints without scaling |
| Orientation | Match the document | Avoids sideways pages |
| Margin | Small or none | A cropped scan already has a white border |
| Fit mode | Fit / contain | "Fill" crops your content off the edges |
| Image quality | High for text, medium for photos | Text needs sharp edges more than photos do |
The PDF is only as good as what goes into it. Before assembling: crop to the page edges, straighten any tilt, and raise contrast until the paper reads as white rather than grey. That last step both improves legibility and dramatically reduces file size, because flat white is nearly free for JPEG to encode while grey noise is expensive.
The phone scanning guide covers capture and clean-up in full.
Photograph both sides, add both images with the front first, and export. You get a two-page PDF. If the portal wants both sides on a single page, place them as two images on one page instead.
You built it from full-resolution photos — a 12-megapixel image is around 4 MB each. Resize the sources to about 1800 pixels on the long edge and rebuild, or run the result through the PDF Compressor.
Yes. Set the orientation per page, or rotate individual pages after assembly with Rotate PDF.
No. This produces a picture of your pages, not text. Making a scan searchable requires OCR, which this site does not offer. For upload purposes it rarely matters, since a person is reading the document.
JPG, PNG, WEBP and HEIC among others. HEIC works directly, so iPhone users do not need a separate conversion step.
No. It is assembled in your browser using pdf-lib and saved straight to your device. The images are never transmitted.
