Best Free Way to Merge Images into One PDF
Combining several photos — a multi-page document shot page by page — into one properly ordered PDF, without installing anything.
A very common situation: you've photographed a multi-page document one page at a time (a contract, an ID's front and back, a multi-page form), and now you need those separate photos to become a single PDF, in the right order, before you can submit anything.
The direct way
- Merge images into one PDF — select your photos, arrange them in the order the pages should appear, get back one PDF
The ordering step matters: most tools (including this one) let you drag to reorder before combining, since photos taken in a batch don't always end up sorted the way the actual document reads.
Watch orientation before merging
If some photos were taken in portrait and others in landscape (easy to do by accident switching hands or hitting a corner of the phone), the merged PDF will have inconsistent page orientation — which looks unprofessional and can confuse whoever's reviewing it. Rotate any misoriented photos before merging rather than after:
Crop out the background first
A phone photo of a document almost always includes some table, desk, or floor around the edges. Cropping tightly to just the document before merging makes the final PDF look like an actual scan rather than a stack of photos:
- Crop image
- Document scanner — if the photos were taken at even a slight angle, this straightens the perspective too, not just the crop
After merging: check the size
Combining several full-resolution phone photos into one PDF can produce a surprisingly large file — multiple megabytes is common. If the destination has an upload limit:
Everything — merging, rotating, cropping, compressing — runs in your browser. None of your photos are uploaded anywhere to combine them.
