Combine Multiple Images into One PDF

There are three common ways to combine images into a PDF: desktop software (Adobe Acrobat, Preview on Mac), operating system features (Windows 'Print to PDF', macOS Finder), and browser-based tools like this one. Each has trade-offs.

Desktop software offers the most features but requires installation and often costs money. OS features are convenient but offer no control over quality or page settings. Browser-based tools like AllImgTools work on any device (phone, tablet, laptop), require no installation, and run completely privately — your images never leave your device. This makes them the most practical for most users, especially on phones.

Expense reports: combine photos of multiple receipts into a single PDF for submission. Most corporate expense systems and accountants prefer one PDF over multiple image files.

Medical records: combine multiple scan or X-ray photos into one document for a specialist referral or insurance claim.

Legal documents: combine pages of a multi-page document photographed with a phone into a single PDF for submission to a court, notary, or attorney.

Property documentation: combine photos of property damage, rental unit condition, or inspection results for landlord/tenant disputes or insurance claims.

Academic submissions: combine photos of handwritten homework, lab reports, or assignments into a single PDF for course management systems that require PDF format.

Our multi-image PDF converter is pre-configured at 90% quality, which provides an excellent balance of visual quality and file size. At 90%, text in document photos remains readable, product images look sharp, and receipt photos are clear enough for accounting.

For documents containing fine text (contracts, handwritten notes, printed forms): use 90-95% quality to ensure text remains legible. For document photos where file size matters more than image detail (bulk filing, email submission): 75-80% quality is acceptable for most typed text and is significantly smaller.
