Preguntes freqüents
Are my BMP images uploaded to a server?
No. All conversion happens in your browser using the Canvas API. Your images never leave your device.
How is the output quality?
PNG output is lossless and supports transparency.
Can I batch-convert BMP files?
Yes - on paid plans. Drop multiple files and they're processed in parallel, then packaged into a ZIP. Free Starter is limited to one file per conversion.
Why use this instead of a different BMP-to-PNG site?
PDFSub does the conversion in your browser - the images never touch our servers. Most online converters upload your files. Yours stay on your device.
Can I convert in other directions?
Yes - try the unified Image Converter, which lets you mix-and-match any of JPG, PNG, WEBP, HEIC, BMP, and TIFF inputs with JPG, PNG, or WEBP output.
