About the BMP to PNG
BMP to PNG converts BMP images to PNG. BMP is an old, uncompressed Windows bitmap — perfect fidelity but very large files, rarely needed now. PNG is lossless and supports transparency, which makes it ideal for logos, screenshots and graphics — at the cost of larger files.
Converting BMP to PNG gives you a lossless copy with transparency, ideal before editing or when a tool demands PNG. The pixels are re-encoded faithfully into PNG. Your image is converted with Imagick on our server, then deleted straight after — stored under a random name in a non-public folder and removed when your download is served. Convert one image or up to 30 in a batch (returned as a ZIP).
Frequently asked questions
Will converting BMP to PNG reduce quality?
The pixels are re-encoded faithfully into PNG.
Does it keep transparency?
Yes — PNG supports transparency, so transparent areas are preserved.
Can I convert several images at once?
Yes — add up to 30 and they come back together as a ZIP. Each is processed on our server and deleted right after.
Are my images kept?
No. They are stored under random names in a non-public folder and deleted the moment your download is served.
