Drop your JPEG image into the upload area. PDF.to re-encodes the pixels into the BMP container and gives you the new file in seconds. No account is needed.
Will the JPEG to BMP conversion lose detail or sharpness?
+
If BMP is a lossless format (PNG, BMP, TIFF), pixel data is preserved exactly. If BMP is lossy (JPG, WebP, JPEG), we use a high default quality setting that is visually indistinguishable from the source for almost all images.
Does the JPEG to BMP converter keep transparency?
+
When BMP supports an alpha channel (PNG, WebP, GIF) and the original JPEG had transparency, we keep it. Converting to a format without transparency (JPG, BMP) fills transparent areas with white by default.
Does it preserve EXIF, color profile, and DPI from my JPEG file?
+
ICC color profiles and DPI tags are preserved when BMP supports them. EXIF metadata (camera, GPS, timestamps) is stripped by default for privacy; turn it on in PRO if you need it.
Can I convert a vector JPEG to a raster BMP (or vice versa)?
What is the largest JPEG image I can convert to BMP?
+
Free accounts allow images up to the free size limit. PRO accounts allow much larger images and up to 1 gigapixel per image, which covers large scans and panoramas.
Can I batch-convert JPEG images to BMP?
+
Yes — drag a folder of JPEG files onto the page. Each is converted independently and zipped into a single download when done.
Will the converted BMP have the same dimensions as my JPEG?
+
Yes — pixel dimensions are preserved by default. If you want to resize during conversion, use the BMP resize tool after the conversion finishes.
Is my JPEG image private when I convert it?
+
Yes. Uploads are encrypted in transit, the conversion job runs on an isolated worker, and the original JPEG plus the resulting BMP are deleted within an hour.
Why is my converted BMP file larger than the original JPEG?
+
If BMP is lossless and JPEG was lossy (or vice versa), file size will change. PNG (lossless) is typically larger than JPG (lossy) for photographs but smaller for solid-color graphics and screenshots.
Does the JPEG to BMP converter handle animated images?
+
If JPEG is animated (GIF, WebP, APNG) and BMP also supports animation (GIF, WebP), all frames are preserved. Converting animated JPEG to a static target (JPG, PNG) keeps only the first frame.
Can I convert JPEG to BMP on my phone?
+
Yes. The converter is mobile-responsive and processes images server-side, so you can convert JPEG to BMP from any iPhone or Android device without using local storage.
