About BMP and PNG

BMP and PNG are both lossless raster formats — the difference is that BMP typically stores pixels raw while PNG compresses them. Converting between them changes nothing about the image itself; it just makes the file web-friendly and far smaller, especially for screenshots, diagrams and graphics with repeated colors.

This is the right conversion when you must not lose any detail — archival scans, technical diagrams, pixel art. For photos where a much smaller file matters more than bit-perfect pixels, BMP to JPG produces far smaller output.

Private by design

Your files are processed directly in your browser using the browser's built-in image APIs and are not uploaded to Filesvo. Nothing is stored on our servers, because nothing ever reaches them.

Frequently asked questions

Is the conversion really lossless?
Yes. PNG compression is lossless by design — the PNG contains exactly the pixels your browser decoded from the BMP.
How much smaller will the PNG be?
It depends on content: screenshots and graphics often shrink by 80–95%, detailed photos less. Filesvo shows the exact size change per file.
Does BMP transparency survive?
The rare 32-bit BMPs that carry an alpha channel keep it if your browser decodes it; standard 24-bit BMPs have no transparency to preserve.
Do my files leave my device?
No. Everything runs in your browser — nothing is uploaded.
