Questions
Is any quality lost?
No. The pictures are stored without loss, so every pixel is the same as in the BMP.
Can I add other images too?
Yes. JPG, PNG, WebP, GIF and TIFF work too, and you can mix them.
Are my files uploaded?
No. The tool runs in your browser, so your files never leave your device. Nothing is sent to us or kept after you close the tab.
Is it free?
Yes. There is no sign-up, no watermark on your file and no daily limit.
Is there a file size limit?
Only what your device can hold in memory. Most phones handle files of a few hundred MB; a computer handles more.
Need to mark up the PDF too?
