Are my images uploaded to a server during conversion?

No. The entire conversion is performed locally in your browser using the pdf-lib JavaScript library. Your images are read from your local disk, processed in memory, and written as a PDF file that is downloaded directly to your device. No image data is ever transmitted over the internet.

Will the PDF output preserve my image quality?

Yes. pdf-lib embeds images at their original resolution without additional compression, so the PDF quality is determined entirely by the quality of the source images you provide. For the sharpest results, use high-resolution PNG images rather than heavily compressed JPGs.

How many images can I combine into one PDF?

There is no hard limit on the number of images, but performance is constrained by available browser memory. Combining dozens of high-resolution images may slow down the browser on low-memory devices. If you encounter slowness, try working in batches of 20–30 images and then merging the resulting PDFs.

Can I control the order of pages in the output PDF?

Yes. After adding images, you can drag and drop them in the list to set the desired page order before converting. The PDF will be generated with pages in exactly the sequence you arrange, giving you full control without needing to re-upload files.

Pro Tip

For the sharpest output, use PNG source images rather than heavily compressed JPGs — pdf-lib embeds images at their original resolution, so starting quality directly determines PDF quality. If file size matters, pre-resize images to the target print dimensions before converting rather than relying on PDF scaling.

Frequently Asked Questions

The tool supports JPG, JPEG, PNG, and WebP images. These cover the vast majority of common image formats produced by cameras, smartphones, and screenshot tools. If you have a different format such as BMP or TIFF, convert it to PNG first using an image editor, then use this tool.
