When submitting applications, invoices, or homework, recipients usually prefer a single file over opening multiple images one by one. A PDF keeps the page order intact, displays and prints consistently across every device, and looks far more professional than a batch of separate JPG files.
PDFs are also easier to attach to emails: instead of attaching 10 separate photos, you just need one file. The recipient also won't have to worry about images getting reshuffled by file name.
How to convert photos to PDF without installing an app
You don't need to install any software or app. Just open your phone's browser (Safari, Chrome, etc.) and use the Images to PDF tool: select photos from your library (or take them directly), drag and drop to arrange the page order, choose A4 paper size, then tap to generate the PDF and download it.
Because the tool runs entirely in your browser, your photos are never sent anywhere — a key difference from many online services that require you to upload images to their servers.
Tips for photographing documents cleanly and using scan mode
To make a document page look like it was run through a scanner, use the tool's built-in scan mode: it automatically detects the paper's four corners and corrects the perspective so the page appears flat and straight, even if you shot it at a slight angle.
When shooting, place the paper on a contrasting background (white paper on a dark table), make sure lighting is adequate, and avoid shadows so the tool can detect the edges more accurately. If the file needs to be emailed, turn on compression to reduce its size.
What else can you do once you have your PDF?
If you need to edit the PDF further — merging in more pages, splitting some out, or rotating pages that came out upside down — use the Merge/Split/Rotate PDF tool. If you want to extract text from a photo so you can edit it, an OCR tool will convert the image into editable text.
