Who Actually Needs to Turn Images Into a PDF
A photo looks different depending on the app that opens it — a PDF doesn't. That consistency is the real reason people convert images to PDF: it's a container format that renders identically whether it's opened on a phone, emailed to an employer, or printed at a copy shop.
- Document Scanning: Combine photos of paper documents — receipts, forms, IDs — into one file instead of sending five separate JPGs.
- Art & Photo Portfolios: Compile artwork or photography into a single document that opens the same way for every reviewer.
- Receipt Archives: Organize photographed receipts into monthly expense reports without a scanner.
- Product Catalogs: Turn a folder of product photos into one shareable catalog PDF.

Why a transparent PNG loses its background here
This converter builds the PDF with jsPDF, and every image — regardless of whether you uploaded a JPG, PNG, or WebP — is written into the PDF as a JPEG. JPEG has no alpha channel, so if you upload a PNG with a transparent background (a logo, for example), that transparency gets flattened onto a white background before it's embedded. This isn't a bug to be fixed with better settings; it's inherent to storing every page as a JPEG internally. If you need transparency preserved, keep the file as a PNG rather than converting it to PDF.
It also means the PDF applies JPEG's lossy compression to every page, including images that started out lossless (PNG, BMP). For photos this is invisible; for sharp line-art, text screenshots, or QR codes, you may notice slight compression artifacts compared to the source file.

Frequently Asked Questions
Why does my PNG lose its transparent background?
Every page in the output PDF is written as a JPEG internally, and JPEG has no alpha channel. Transparent areas get flattened onto a white background before embedding — this happens for every PNG or WebP source, not just some of them.
Can I control the JPEG compression quality?
Not currently — this tool uses jsPDF's default image quality setting rather than exposing a quality slider. For photos the difference is negligible; for very sharp graphics you may want a dedicated image editor instead.
What page size and margins does the PDF use?
Standard A4 with a 10mm margin on every side. Each image is scaled to fit within that margin while preserving its aspect ratio, then centered on the page.
Is there a limit on how many images I can convert?
There's no hard cap, but very large batches are limited by your device's memory since everything happens in the browser tab. We recommend 50 images or fewer per run for reliable performance.
Are my images uploaded anywhere?
No. jsPDF runs entirely client-side — images are read with the File API and assembled into the PDF in memory, then handed to the browser as a downloadable file.

How We Compare
DocuTools
A single-purpose converter: images in, one PDF out, nothing uploaded. There's no OCR, no compression controls, and no account system — trading feature breadth for a tool you can use in one visit without creating anything.
Smallpdf
Better for occasional multi-tool use
Smallpdf bundles image-to-PDF with dozens of other document tools in one account, which is convenient if you're already a subscriber. The free tier is capped at a small number of tasks per day before it pushes you toward a paid plan, and files are processed on their servers.
Choose Smallpdf instead if: you already use Smallpdf for other document tasks and want everything under one account.
Adobe Acrobat
Better for offline, enterprise use
Acrobat's desktop app converts images to PDF without an internet connection at all, and integrates with the same review/sign workflows enterprises already use Acrobat for. It's a paid subscription, and the web version still requires uploading files to Adobe's servers.
Choose Adobe Acrobat instead if: you need offline conversion or already have an Acrobat license for other PDF work.
