What is Image to PDF Conversion?
Image to PDF conversion turns one or more image files into a PDF document, with each image placed on its own page. This is useful when you need to share photos as a professional document, combine scanned pages into a single file, submit image-based documents to a portal that only accepts PDF, or archive a set of images in a universally readable format. If you need to turn scanned image text into editable Word files, check our OCR PDF tool or PDF to Word converter.
How to Convert Images to PDF Without Losing Quality
PDFLinx preserves the original resolution and quality of every image during conversion. There is no compression applied to the image content unless you specifically choose it — your photos and scans will look exactly as sharp in the PDF as they do in the original files. Read our guide on how to convert images to PDF without losing quality to learn optimal resolution settings for scans and photos.
Why PDFLinx is the Best Free Image to PDF Converter — No Watermark, No Limits
Most free image to PDF converters add watermarks, limit the number of images you can combine, or require account creation. PDFLinx does none of that — completely free, no signup, no watermark, and no daily conversion limit. Unlike iLovePDF free tier and Smallpdf free tier which restrict batch image uploads behind paid plans, PDFLinx gives you unlimited conversions at zero cost.

Image to PDF vs Printing to PDF — Why a Proper Converter Gives Better Results
Some people try to convert images to PDF by opening them in a browser and using Print to PDF — but this approach adds margins, scales images incorrectly, and often introduces white borders or page breaks at wrong positions. A dedicated image to PDF converter like PDFLinx places each image as a full page without margins or distortion, giving you a clean, properly formatted PDF that looks exactly as intended.
Supported Image Formats
PDFLinx supports all common image formats for PDF conversion — JPG and JPEG for photographs, PNG for graphics and screenshots with transparency, WebP for modern web images, BMP for Windows bitmap files, and GIF for simple graphics. Read our blog guide on PDF to JPG vs PNG differences or explore our roundup of the best free image converter tools.
Best For Everyday Document Management
Use the converted PDF for submissions, email attachments, official applications, archiving, and sharing. The output is a standard PDF file compatible with Adobe Acrobat, Preview, Chrome, and every PDF viewer. If the generated PDF is too large for email attachments, quickly compress your PDF file size before sending.
