Can I combine multiple photos into one PDF on my iPhone or Android without an app?

Yes. Open Vexolora’s JPG to PDF Converter in Safari or Chrome, select your photos, reorder them if needed, and download a single merged PDF.

Are my ID or receipt photos uploaded to a server?

No. The multi-page PDF is generated locally in your browser memory.

Can I reorder the pages before downloading the PDF?

Yes. Each image in the queue has Up, Down, and Remove buttons so you can set the exact page order.

How do I keep the merged PDF file size small for email?

Our PDF builder encodes embedded pages at optimized JPEG quality—or you can pre-compress large photos in our Image Compressor.

Does Vexolora add watermarks to the PDF?

Never. Every page of your exported PDF is 100% watermark-free.

Why Use This Platform?

Verifiable Local Privacy & Binary Precision

Most online converters upload your confidential shipping labels, family photos, and CSV databases to remote server queues. Vexolora processes your files directly inside your browser's volatile memory (RAM) using standard Web APIs (ArrayBuffer, DataView, DOMParser, and HTML5 Canvas).

✓ Zero Server File Storage: Core tools never upload your files—verify it yourself in your browser's Network tab.
✓ True Binary Header Editing: Our 300 DPI Scrubber writes 9-byte PNG pHYs chunks and JPEG JFIF headers without re-encoding pixels.
✓ Batch & ZIP Ready: Process up to 100 images at once and download a single standards-compliant ZIP archive.

How to Combine Multiple Photos (JPG, PNG & HEIC) into One PDF on Your Phone or Computer Privately

When an employer, university, bank, or government portal asks you to upload a multi-page document—such as the front and back of an ID card, a 5-page signed lease, or a stack of expense receipts—taking pictures with your phone gives you separate image files. With the Vexolora JPG & PNG to PDF Converter (and HEIC to PDF), you can merge those photos into a single PDF document right in iOS Safari, Android Chrome, or any desktop browser without uploading a single byte to a server.

1. Choosing the Right PDF Page Size

Page Size Preset	PDF Points (72 pt/in)	Best Use Case
A4 (210 × 297 mm)	`595 × 842 pt`	International contracts, invoices, and university portals
US Letter (8.5 × 11 in)	`612 × 792 pt`	North American office printing and tax receipts
4 × 6 in Thermal Label	`288 × 432 pt`	Shipping labels and warehouse packing slips
Fit Page to Image	Matches image ratio	Portfolios, slides, and zero-border mobile viewing

2. Step-by-Step: Merge Photos into One PDF on iPhone, Android, or PC

Open vexolora.online/tools/jpg-to-pdf in your phone or computer browser.
Tap Choose Image Files and select all the photos from your camera roll.
Use the ↑ Up and ↓ Down buttons next to each thumbnail to arrange your exact page sequence.
Select A4 or US Letter with a 20 pt margin, and tap Download Result.
