Screenshots have quietly become the default way people keep records: a payment confirmation, a conversation with support, an error message, a booking reference. The problem arrives when you need to *send* twelve of them to someone. Twelve separate image attachments is a mess. One PDF is a document.
The straightforward way
Screenshots are PNG files on most systems — Windows Snipping Tool, macOS Shift-Cmd-4, iPhone and Android all default to PNG.
If your screenshots are JPGs — some Android phones and screenshot apps default to JPG — use JPG to PDF instead. Everything else works the same.
Both run in your browser, so screenshots of your bank app or a private conversation are not uploaded anywhere.
Get the order right before you convert
This is the part people redo. Screenshots are usually named by timestamp — "Screenshot 2026-05-18 at 14.23.11" — so they *often* sort correctly by default, but not always. Two traps:
Screenshots taken on different devices interleave badly, because the naming schemes differ.
Files renamed by a messaging app lose their timestamps entirely. Anything that arrived via WhatsApp or Telegram will have a name like "IMG-20260518-WA0007", which sorts by arrival, not by when it was taken.
Drag the thumbnails into the order that tells the story, then convert. Fixing the order afterwards means starting again.
Getting screenshots off your phone first
If the screenshots are on your phone and you want to do this on a laptop, the fastest routes are:
Or skip the transfer entirely. The converter works in mobile browsers, so you can select screenshots straight from your phone's photo picker in Safari or Chrome and get the PDF back into your Downloads folder. There is no app to install.
A note on iPhone screenshots and HEIC
Screenshots on iPhone are PNG, so they convert directly. But *photos* on iPhone are usually HEIC, and if your bundle mixes screenshots with camera photos, the HEIC files will not convert directly. Run those through HEIC to JPG first, then combine everything.
Long screenshots and readability
Two practical things that make the resulting PDF more useful:
Scrolling screenshots get scaled down. A tall scrolling capture of a whole chat thread has an extreme aspect ratio, so fitting it to a page shrinks the text considerably. If legibility matters, take several normal screenshots instead of one enormous scrolling one.
Crop before you convert. Your status bar, battery percentage and notification shade are not part of the evidence. Cropping tightly to the relevant area means the content fills more of the page and is easier to read.
If the PDF is too big to email
Screenshots are lossless PNGs, so twenty of them can easily produce a 15MB PDF. Run it through the compressor with a target of 2MB or so — screenshots tolerate compression well, since they are mostly flat colour and text on plain backgrounds.
