The best PDF maker is the one you skip installing

Match the route to your source

Start from what you have, not from the app store. A train ticket in your email, a receipt in a web shop, a form filled in on screen: all of it becomes a PDF through the print dialog or the share sheet, at no cost and with the text staying selectable. Students saving lecture slides, tenants saving rental listings, anyone archiving a confirmation page: this route covers them, and it produces a real document rather than a photograph of one.

A pile of paper is the opposite case. Twelve warranty cards spread on a kitchen table will not print themselves to PDF, so photograph them and drop the shots into the image tool, which lays JPG and PNG files out as pages at A4 or US Letter with a margin you pick. iPhone shots go through the HEIC route with no conversion step. Only when the pile grows into a weekly habit does a dedicated scanner app earn its place.

Four ways to make a PDF

One table, four routes, judged on what each demands from you and what it gives back.

Where apps beat the built-ins

Capture at volume. When the source is paper on a table and there is plenty of it, an app that drives the camera finds page edges, corrects perspective and clears the table out of the background while the shutter is still open. CamScanner is the familiar example: its site lists capture modes, background cleanup, text extraction across 41 languages and sync between devices, checked 20 August 2026. For the capture side in full, the scanner roundup compares the options, including the free capture already on your phone.

The second app-shaped job is design. When the PDF is a poster, a menu or a pitch deck laid out from scratch, Canva is the answer, with a paid plan for the full export set. And when the job is converting between formats rather than creating, TinyWow and the other free suites cover conversions this site does not do. Use the right specialist instead of forcing one tool into every shape.

Where the browser fits

Between capture and delivery. The image tool detects the format from the file bytes, preserves decoded pixel dimensions and offers A4 or US Letter with a margin of your choice, or pages matched to each image. The JPG route names the common case of that same tool, and it all runs in a phone browser as well as on a laptop.

Then fix the result before sending it. A photo-built PDF runs large, every page a full-resolution image, so set a kilobyte target and work down to it. Page order and rotation get fixed the same way, locally, with nothing uploaded. For edits on a desktop afterwards, the free editor roundup picks the tool by the job.

How we checked

We matched the built-in routes against current phone and desktop behavior described generically, reused the CamScanner claims with their 20 August 2026 check date, and verified the image, HEIC and compressor behavior in this repository's tool pages. We installed no apps and ran no timed tests; prices stay generic except where a checked figure is quoted.
