What Actually Happens When an Image Becomes a PDF
A JPG or PNG is a grid of pixels with no concept of a "page." Converting to PDF means each uploaded image is placed onto its own page at a defined page size (commonly A4 or Letter), scaled to fit within the page margins while preserving its original aspect ratio — this is why a very wide photo ends up with white space above and below it on the page, rather than being stretched to fill the entire sheet.
Multiple images become multiple pages, in upload order. If you upload three photos, you'll get a three-page PDF with one image per page, in the same order you selected them. This matters if you're assembling a scanned multi-page document from individual photos — select your files in the order the pages should appear, since most file pickers don't automatically sort by filename or capture time.
Image resolution carries over directly. A low-resolution screenshot or a heavily compressed photo will look exactly as sharp (or soft) inside the PDF as it did as a standalone image — conversion doesn't add or remove detail, it just repositions the existing pixels onto a page. If a scanned document needs to be legible when printed, the source photo needs to already be sharp and well-lit before conversion.
PNG vs. JPG source makes a small but real difference. A PNG source (lossless) will produce a marginally sharper result in the PDF than a heavily compressed JPG of the same photo, though for most everyday documents (receipts, forms, notes) the difference isn't noticeable. It matters more for scanned text you'll need to re-read closely, less for casual reference images.
Getting a Clean, Scan-Quality Result from a Phone Photo
Most people using this tool are photographing a physical document rather than converting an existing digital image. A few things that make the biggest difference to legibility:
Shoot straight-on, not at an angle
A photo taken at an angle introduces perspective distortion — text near the camera looks larger than text further away. Position the camera directly above the document, parallel to the page, for even, readable results.
Even lighting, no direct flash
A camera flash on glossy paper creates a bright glare that can wash out text entirely. Natural, diffuse light (near a window, avoiding direct sun) generally produces the most even, readable result.
Fill the frame with the document
A document photographed from far away with lots of background wastes most of the image's resolution on the table it's sitting on. Getting closer (or cropping tightly before uploading) means more actual pixels are dedicated to the text itself.
One page per photo, in order
For multi-page documents, photograph each page separately rather than trying to capture a spread — then upload the files in reading order, since the PDF pages will follow your upload order exactly.
