PNG to BMP: what it is and when to use it

Converting PNG to BMP is used with older software that only reads this format. Keep in mind the resulting file will be larger than the original.

About the formats: PNG — uses lossless compression and supports transparency, which makes it ideal for screenshots, logos, graphics, and sharp text; the trade-off is that photos weigh more than in JPG. BMP — stores the image uncompressed, so it offers maximum fidelity but very large files that are impractical to share.

With Rayo PDF GO you choose your PNG images, convert them to BMP, and save the result on your device. You can convert several at once and adjust quality or size before saving. Nothing is uploaded to the internet.

Common uses

Open PNG images in programs that only support BMP.
Meet format requirements on forms and portals.
Prepare BMP images for publishing or printing.
Convert whole batches at once.

Tips for better results

Choose the quality before converting when the target is JPG.
Always keep the original.
If the file is large, resize or compress it afterward.

Are my images uploaded to a server?

No: the conversion happens on your device.
