Convert BMP images to PNG with lossless compression. Smaller files, no quality loss. Free, processed in your browser.
100% free and unlimited, with no sign-up, no watermarks, and no 5-file paywall. Files are processed locally in your browser and never leave your device.
BMP to PNG helps with website uploads, email attachments, social media assets, marketplace product photos, profile images, screenshots, and design handoffs where the receiving app expects a specific image format or size.
The file work happens in your browser. Your file is not uploaded to FilesFlow servers, which keeps private documents faster to process and easier to control.
For best results, keep the original image, convert from the highest-quality source you have, and review transparency, sharp edges, and file size before sharing. Converting a low-quality image to another format cannot restore detail that was already lost.
Use this tool when you need a fast format or size fix in the browser. For advanced retouching, layered edits, color-managed print work, or manual background cleanup, finish the file in an image editor.
BMP to PNG is made for quick browser-based image work. Use a dedicated image editor when you need layers, masking, retouching, manual cropping, or print color controls.
