Drop your BMP file into the picker and our encoder produces a JPEG output tuned for web delivery: quality factor 80 by default (a Lighthouse sweet-spot), correct color space, and an Accept-aware fallback you can ship behind a `<picture>` element alongside the original BMP.
Will JPEG actually be smaller than BMP?
+
Almost always when going from PNG / JPG / TIFF into WebP or AVIF: expect 25-50% smaller than JPG at the same visual quality, 60-90% smaller than PNG. Going the other way (WebP / AVIF back to JPEG = PNG / JPG) typically grows the file because you are leaving a more modern codec for an older one — useful for compatibility, not size.
Does BMP to JPEG preserve transparency / alpha?
+
Transparency survives when JPEG supports alpha (PNG, WebP, AVIF, GIF, TIFF, SVG). Converting to JPG flattens the alpha channel onto white — if you need transparency on the modern web target WebP or AVIF instead of JPEG.
Can I keep my color profile (sRGB / Display P3) going from BMP to JPEG?
+
Yes for JPEG formats that store ICC profiles (PNG, JPG, WebP, AVIF, TIFF). Modern wide-gamut profiles like Display P3 round-trip through WebP and AVIF; sRGB profiles round-trip through every common JPEG. If JPEG cannot store a profile, output is tagged sRGB to keep browsers from guessing.
What lossy vs lossless quality settings does the JPEG encoder support?
+
Lossy JPEG (WebP / AVIF / JPG) accepts a quality 1-100, default 80. Lossless JPEG (PNG / WebP lossless / TIFF) does not take a quality dial — every pixel is preserved. WebP and AVIF are the only formats that can do either, which is why they are ideal JPEG targets when source BMP mixes photos and graphics.
Will the JPEG version look identical to the BMP on a Retina display?
+
At quality 80+ on WebP / AVIF the difference is invisible to anyone but a trained eye even at 3x device pixel ratio. Photos compress slightly more visibly than line art; if your BMP is screenshots or UI mockups, push quality to 90 or use a lossless JPEG.
Does BMP to JPEG keep animation frames?
+
Animated BMP (animated WebP, GIF, APNG) survives only when JPEG is also animation-aware (animated WebP, GIF, APNG). Converting an animated BMP to a static JPEG (PNG, JPG, AVIF still) yields just the first frame — use a dedicated animation converter if you need to keep all frames.
Will EXIF camera metadata survive BMP to JPEG?
+
Yes by default when both BMP and JPEG support EXIF (JPG, PNG, WebP, TIFF, HEIC). Camera fields (ISO, shutter, lens, GPS) are copied through. Use the "strip metadata" option if you are publishing to the web and want to drop GPS coordinates before JPEG leaves your browser.
Can I batch convert a folder of BMP files to JPEG?
+
Yes — drop multiple BMP files at once and they encode in parallel. Free accounts: 100 MB per file. Pro accounts get more parallel workers and bigger per-file caps, so a 200-image gallery typically finishes in well under two minutes.
Are my BMP files private during JPEG conversion?
+
Yes — uploaded BMP files are processed in isolated workers and deleted within minutes. No human reviews the pixels, no copy is retained, no third party gets a feed. See /privacy/ for the precise retention window.
How do I serve the JPEG with a BMP fallback on my site?
+
Use a `<picture>` element: `<picture><source srcset="image.JPEG" type="image/JPEG"><img src="image.BMP" alt=""></picture>`. Browsers that understand JPEG fetch the smaller file; older browsers fall back to BMP. WebP is supported in 96%+ of installed browsers, AVIF in 90%+.
Why is my JPEG file unexpectedly bigger / smaller than I expected?
+
A BMP that is already heavily compressed (low-quality JPG) often grows when re-encoded into a lossless JPEG (PNG / TIFF). A high-bitrate lossless BMP (PNG / TIFF) often shrinks 60-90% when going to a lossy modern JPEG (WebP / AVIF). Image content matters too — photos compress very differently from line art and screenshots.
