Frequently asked questions
Which image formats can I convert?
JPG, PNG, WebP, GIF, and BMP — and you can mix them freely in one batch.
Will my images lose quality in the PDF?
No. Images are embedded at their original resolution; the PDF is just a container around them.
Can I put multiple images on one page?
The default is one image per page. For contact-sheet layouts, convert first, then use Crop PDF to trim as needed.
How do I control the page size?
Choose A4 for documents, “Fit to image” for photos, or “Original size” to match each image's pixel dimensions.
Is there a limit on image count or size?
No fixed limit. Assembling runs in your browser; very large batches depend on your device memory.
Are my photos uploaded during conversion?
No. The PDF is built entirely on your device — nothing is transmitted anywhere.
