Convert images to a PDF

Match each image makes every page exactly the size of the photo on it. Nothing is scaled, cropped or re-compressed, so the PDF is as sharp as the originals and only slightly larger than them added together.

A4 portrait centres each photo on a standard page with a small margin. Choose this whenever the file is going to be printed or uploaded to a portal that expects paper-shaped pages — mixed page sizes are what makes a submission print half-size on one sheet and off the edge on the next.

Handwritten assignments are the obvious one: photograph each sheet, drop the photos in, order them, and you have a submittable PDF without a scanner. The same for a lab record with a hand-drawn circuit, a signed form you photographed rather than scanned, or a whiteboard from a revision session you want to keep with your notes.

Shoot in decent light and hold the phone square to the page — that does more for legibility than any setting on this page.

Photos of handwritten work are personal, and often have your name, roll number and hostel address written across the top. They stay on your phone or laptop: the images are read locally, drawn into a PDF locally, and handed back as a download. There is no upload step in this tool.

JPG and PNG only. iPhone HEIC photos are not supported by browsers for this purpose — set your camera to “Most Compatible” or share the photos as JPG first. The file's real bytes are checked, not just its name, so an image renamed to .jpg is caught and reported rather than producing a broken page. Very large batches are capped by how much a browser tab can hold; build two PDFs and merge them if you hit it.
