How to Convert Images to PDF on Your Phone
Quick answer: Open Images to PDF on your phone's browser, select your photos or screenshots, and download a PDF — no app install, no account, free on iPhone and Android.
Table of Contents
You just took a photo of a signed contract, a whiteboard full of notes, or a stack of receipts. Instead of emailing three separate image files, you need a single PDF — and you need it now, without transferring files to a laptop.
PDFslime's Images to PDF tool runs entirely in your phone's browser. No app store, no sign-up, no file uploads to a server.
Why Convert on Your Phone
- No file transfers needed: your images are already on your phone — convert them right there instead of emailing them to yourself.
- Instant sharing: create a PDF and send it via WhatsApp, email, or Slack in one flow.
- No app install: PDFslime is a web tool — nothing to download, nothing to delete later.
- Privacy: conversion happens locally in your browser. Images never leave your device.
Step-by-Step Guide
- Open Safari (iPhone) or Chrome (Android) and go to pdfslime.com/img2pdf.
- Tap the dropzone or browse to open your photo library.
- Select one or more images — you can pick photos, screenshots, or scanned documents.
- Use the up/down arrows next to each image to arrange them in the order you want.
- Tap Create PDF.
- Download the file — it lands in your phone's downloads folder, ready to share.
The entire process takes under a minute. The PDF keeps each image at its original resolution — no quality loss, no forced resizing.
Tips for Best Results
- Use Safari on iPhone: it gives direct access to the photo library with no extra steps.
- Enable desktop mode in your browser if the layout looks cramped — tap the "AA" icon in Safari or the three-dot menu in Chrome.
- Rotate images first if any are sideways — the tool preserves whatever orientation they're in.
- Combine receipts into one PDF for expense reports — much cleaner than sending 12 separate photos.
- For very large batches (20+ images), keep your phone plugged in and avoid switching apps during conversion.
