    About the formats

    BMP (Bitmap)

    BMP stores images without compression. Files are large, but the format is simple and supported by almost every Windows program.

    JPG / JPEG

    JPG is the most widely supported image format. Its compression keeps photos small, which makes it ideal for email, websites and social media.

    Frequently asked questions

    BMP usually stores every pixel without compression. JPG compresses the image, which makes the file much smaller.

    JPG uses compression, so there is a small loss, but at 92% quality it is very hard to see in photos and screenshots.

    JPG does not support transparency, so transparent areas become white.

    No. PDFdays converts files directly inside your web browser, on your own device. Your files are never uploaded, so nobody else can see them.

    PDFdays sets no fixed limit. Because your own device does the converting, very large files or big batches depend on its memory — a computer handles more than an older phone.
