How to Convert PDF to JPG/PNG and JPG/PNG to PDF Quickly Without Losing Quality (2026 Tested Guide)

Converting a PDF to images or combining multiple images into a PDF sounds easy until image quality, file size, batch processing, and formatting start to matter. Some tools noticeably reduce quality, while others offer better results but lock useful features behind paid plans.

So instead of relying on feature lists and online recommendations, I decided to test the popular free PDF and image converters myself.

For this guide, I tested PDFgear, PDF24 Tools, LightPDF, PDF Candy, and iLovePDF using the same standard documents, multi-page PDFs, and image batches.I compared output quality, format preservation, speed, batch conversion, customization, and free-version limits to see which tools actually deliver the best results. The differences were more noticeable than I expectedand the results may help you choose the right converter without wasting time testing them all yourself.

How I Tested the AI Converters

PDF to Image Testing

I tested each converter using the multi-page PDF containing text, tables, images, and colored graphics. Every tool was evaluated for format preservation, color accuracy, image sharpness at different zoom levels, available output formats (JPG/PNG), ZIP file organization, processing speed, batch conversion capabilities, and any free-version limitations.

Image to PDF Testing

I tested each converter by uploading large collections of images and screenshots to create a single PDF. The evaluation focused on conversion speed, page order accuracy, batch image support, final PDF quality, file organization, and whether the generated PDF preserved the correct number and sequence of pages under the free version.

Converted PDF pages are downloaded as a ZIP folder containing individually named images, such as P1, P2, and P3, making multi-page documents easy to organize and identify.

Free Version Limitations:

The free version does not offer DPI or image quality adjustment options, and it cannot process multiple PDF files in a single conversion task.
