Images to PDF Converter — Turn JPG, PNG, HEIC & Any Format Into One PDF

Convert Images to PDF Online — Free, No Uploads

Images to PDF is one of those tasks that sounds simple until you realise your photos are in five different formats. An iPhone saves shots as HEIC. A scanner spits out TIFF. A designer sends you an SVG logo. A screenshot is PNG, a JPEG is what you downloaded from a stock site, and a GIF snuck in there from a chat thread. This tool takes all of them and turns them into one clean PDF — no uploading, no account, no conversion limits.

Everything runs client-side using JavaScript and the jsPDF library, which means the images stay on your machine from start to finish. That matters if you're working with contracts, IDs, medical scans, or client material you'd rather not hand to a third-party server.

Which Image Formats Work With This Converter

The list covers everything you'll realistically throw at it. JPG and JPEG (the universal photo format), PNG (lossless with transparency), WebP (the modern web format Google recommends), HEIC and HEIF (the default iPhone capture format since iOS 11), SVG (vector graphics for logos and icons), GIF (including animated files, which are captured as a single frame), BMP (Windows bitmap), and TIFF (the print and archiving standard). You can mix any combination in the same PDF.

How the Conversion Actually Works

When you add a file, the browser loads it into memory and renders it at its native size. HEIC and HEIF files pass through the heic2any decoder so they display as normal images. SVG files are rasterised at their native resolution, so a vector logo stays crisp. Each image is then embedded into a new PDF page sized according to your settings — Auto Fit, A4, Letter, or the original image dimensions. The finished PDF is generated entirely in your browser and downloaded directly, with nothing ever leaving your device.

Common Uses for Image to PDF Conversion

• Turning a folder of iPhone photos into a single shareable PDF album.
• Combining scanned receipts, invoices, or expense slips into one document for accounting.
• Building a portfolio PDF from mixed JPG and PNG design mockups.
• Turning product photos from a phone shoot into a PDF catalogue for a client.
• Merging whiteboard photos into a single PDF for meeting notes.

Page Sizes and Orientation

Auto Fit matches the PDF page to the image, which avoids any white borders or scaling. A4 and Letter are the standards for printing and business documents — pick these when the PDF needs to look like a normal report or invoice. Original Image Size keeps the exact pixel dimensions so no re-scaling happens. Orientation can stay on Auto, or you can force Portrait or Landscape when you want a consistent layout across pages.

Why Not Just Use an Online Converter That Uploads Files?

Services like Smallpdf, iLovePDF, or Adobe's online tools upload your files to a server, process them there, and send back a download link. That's fine for a random meme, but less fine for anything with your name, address, signature, or client data on it. This converter skips the server entirely. Your files stay in your browser tab and disappear the moment you close it.
