Who this guide is for

This guide is for Android users creating PDFs from camera images and scanned documents. It is tuned for real mobile constraints like limited memory, upload caps, and variable image quality.

Step-by-step workflow

Open JPEGtoPDF.io in Chrome and add all images from Gallery or Files.
Sort pages in order and rotate any pages that imported incorrectly.
Choose page size, margins, and quality settings based on submission needs.
Convert, download, and preview the PDF before sharing.

Recommended settings

Everyday submissions: 144 DPI, medium compression.
Smaller file target: 120 to 144 DPI, medium-high compression.
Print-ready: 240 DPI+, low-medium compression.

Common mistakes to avoid

Uploading heavily compressed chat images instead of original photos.
Keeping very large batches on low-memory devices without splitting.
Skipping a final readability check on small text.

Practical tip

For older phones, process in smaller batches and close background apps before converting. That alone solves most stability issues during larger workflows.

Android file picker tips

Android file selection can look different depending on the phone brand, gallery app, and cloud provider. If Google Photos does not allow the multi-select flow you expect, use the system Files app or move the images into a temporary folder first. A folder with names such as 01-front, 02-back, and 03-receipt makes the final order easier to verify.

Chrome and download behavior

Current Chrome is the most reliable starting point on Android because it supports modern local file APIs and usually handles downloads consistently. After export, check the Downloads folder or the browser download tray. If a share sheet fails, download the PDF first and then share from Files.

Large batches on Android

Android phones vary widely in memory. A recent flagship can handle more full-resolution photos than an older budget phone. If the tab becomes slow, split the work into smaller groups, lower DPI to 144, and close other heavy apps. Receipt bundles and class notes are often easier to process in groups of 20 to 30 images than as one giant batch.

Camera photos versus screenshots

Use medium compression for camera photos and a little more DPI for screenshots or text-heavy images. Screenshots can look rough if compressed too aggressively, while camera photos usually tolerate stronger compression. Always open the exported PDF and zoom into the smallest text before sending.

Google Photos and cloud originals

Some Android galleries show cloud-backed images that are not fully stored on the device. If selection is slow or a file fails, download the originals first or move them into a local folder. This is especially helpful for older receipts, WhatsApp images, and photos restored from backup.

Android troubleshooting checklist

If Download does not appear, check Chrome downloads and the Files app.
If sharing fails, download first and share the saved PDF.
If the browser reloads, split the batch and use 144 DPI.
If HEIC files fail, export JPEG copies from your gallery app.
