Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert bulky BMP bitmap images to compressed JPG files instantly on ConvertX. This tool is essential for anyone needing to drastically reduce image size for web sharing and storage.
BMP is an uncompressed raster image format that preserves every single pixel in raw detail, leading to massive file sizes. JPG is a lossy raster format that uses compression algorithms to drastically decrease the file size. When you convert BMP to JPG, the encoder analyzes the image data and permanently discards redundant pixel details that the human eye barely notices.
Because you are converting from a lossless format to a lossy format, a small amount of image data is discarded to achieve the smaller file size.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
