How to convert images to PDF
- Drop your images. JPG, PNG, and WebP all work, and you can mix them in one batch.
- Put them in order. Drag the previews around and delete any you don't want. Options has A4 and Letter if the pages need to match.
- Create PDF, then Download. The file is assembled right here, on your device.
Scans, receipts, and applications
Somewhere out there is a portal that accepts "one PDF," and what you have is eleven photos on a phone. Drop them in, get the order right, download. No account, no watermark stamped across your ID scan. And since nothing is sent anywhere, it's fine for the passport page and the signed contract too.
Page size: why "auto" can produce a huge page
There are two ways to decide how big a page should be, and the difference catches people out when they go to print.
Auto makes each page exactly as big as its image, treating one pixel as one PDF point. Points are 1/72 of an inch, so a 4000-pixel-wide phone photo becomes a page around 55 inches wide. On screen this is invisible and harmless: viewers scale the page to your window, and the image fills it perfectly with no margin and no cropping. Send it to a printer, though, and you have asked for a poster.
A4 or Letter creates a normal page and fits the image inside it with a small margin, keeping the proportions and centring what doesn't fill the space. Every page ends up the same size regardless of what the images were, which is what you want for anything that will be printed, bound, stapled, or merged into an existing document.
The rule of thumb: choose auto for screen-only documents where you want the image edge to edge, and A4 or Letter for anything with a chance of reaching paper. If you pick wrong, Resize PDF will normalise the pages afterwards rather than making you start again.
Quality, orientation and file size
JPEGs are embedded exactly as they arrive, without being decoded and re-encoded, so no generation loss creeps in: the photo in the PDF is the same data as the photo on your disk. PNGs are re-packed with lossless compression, which likewise preserves every pixel. Whatever you put in is what comes out.
That fidelity has a cost: a dozen photos from a modern phone can make a PDF of 50 MB or more, which many email systems and upload forms will refuse. Compress PDF is the answer, and it can hit a specific ceiling like 1 MB if that's what the form demands.
If a photo comes in rotated, the culprit is usually the orientation flag cameras record instead of rotating the pixels. Fix it in your photo viewer before converting, or drop the finished PDF into Rotate PDF and turn the page.
Common uses for converting images to PDF
- Turn phone photos into a PDF: snapshots of a document, combined into one file to submit.
- Make a receipt PDF: photograph the receipts, get one PDF for reimbursement.
- Build a photo portfolio: arrange JPGs or PNGs into an ordered portfolio.
- Scan with your camera: no scanner in the house? Photograph the pages and assemble them here.
Frequently asked questions
How do I turn JPG or PNG photos into one PDF?
Drop them above or click to browse, drag the thumbnails until the order looks right, then hit Create PDF. One image per page, and the download starts as soon as it's built.
Which image formats work?
JPG and PNG go in directly at full quality. WebP and most other formats your browser can open are converted on the way in. HEIC is the awkward one: iPhone photos work only where the browser can decode them, so export to JPG first if yours can't.
Are my photos compressed or resized?
They go in untouched. Same pixels, same quality. Each page defaults to the size of the image it holds, so if you want uniform paper, pick A4 or Letter under Options and every image gets centered on the page.
Are my photos uploaded anywhere?
Nothing is sent. A photo carries more than the picture, from faces to street signs to whatever sits in its metadata, and assembling the PDF locally keeps all of that where it started.
