Quality reduction ahead
BMP is uncompressed, meaning every bit of data is preserved. MP4 uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
What compression artifacts to expect
MP4 lossy compression can produce blockiness, banding in gradients, mosquito noise. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
静止画のBMPを動画のMP4へ変換することは、単なるファイル形式の変更に留まりません。例えば、一枚絵に過ぎなかったイラストに動きを加え、まるでアニメーションのように見せることで、より感情豊かな表現が可能になります。また、ビジネスシーンにおいても、詳細な図面や資料のBMPを、プレゼンテーションや共有に適したMP4動画に変換することで、情報の伝達効率を格段に向上させることができます。手軽な操作で、お手持ちのBMP画像を、物語性豊かな動画コンテンツへと昇華させてみませんか。当社の変換ツールは、お客様の大切な画像を、高品質なMP4へとスムーズに変換し、新たな表現の可能性を広げるお手伝いをいたします。

日本のアニメーション制作現場では、原画や背景画をBMPで作成し、その後の工程で動画形式に変換するケースが多く見られます。BMPからMP4への変換は、この流れにおいて重要な役割を担うことがあります。
About BMP to MP4 Conversion
Short answer: yes, you can convert BMP to MP4 online for free, and quality is well preserved with the right settings. Just upload your .bmp file to CocoConvert, pick MP4 as the output, and click Convert. The whole process takes seconds.
Now for the details. BMP is an uncompressed raster format that preserves every pixel but produces very large files. MP4 (MPEG-4 Part 14) is the universal video container supporting H.264/H.265 codecs — plays on virtually every device. Converting between these two formats lets you reduce file size without visible quality loss.
Full Name: BMP uses Bitmap Image, while MP4 uses MPEG-4 Part 14. Compression: BMP uses None (uncompressed), while MP4 uses Lossy. Transparency: BMP uses No, while MP4 uses —.
Your BMP file is decoded and re-encoded as MP4. MP4 lossy compression can produce blockiness, banding in gradients, mosquito noise. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is BMP to MP4 conversion free?
Yes. CocoConvert offers free BMP to MP4 conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is BMP to MP4 conversion?
Most files convert in 2–10 seconds depending on size. Large image files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded BMP file and the converted MP4 file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting BMP to MP4 lose quality?
MP4 lossy compression can produce blockiness, banding in gradients, mosquito noise. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
Can I convert MP4 back to BMP?
Yes, CocoConvert supports MP4 to BMP conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
