JPG to BMP
Converting a .jpg image to .bmp re-encodes the pixels for a different balance of size, quality, and support. Free, private, and validated — the file never leaves your browser.

Converting a .jpg image to .bmp re-encodes the pixels for a different balance of size, quality, and support. A .jpg file is a photograph or other continuous-tone image compressed with the JPEG standard, the most widely used image codec ever shipped. Nearly every camera, phone, and website produces or accepts .jpg files, which makes it the default interchange format for photos.
A .bmp file is the Windows bitmap format: raw pixel rows written to disk with a small header and, in the common case, no compression at all. Its brute simplicity makes .bmp trivial to read and write from any programming language, which is why it persists in tooling, embedded systems, and quick debugging dumps. For this route the practical draw is dead-simple structure with no decoding step at all and exactly lossless — what you write is what you read — balanced against no effective compression, so files dwarf PNG equivalents of the same image, which is worth knowing before you commit a large batch.
Why convert JPG to BMP?
The practical trigger for this conversion is usually a mismatch: with .jpg, every re-save re-compresses the image, so quality erodes across editing generations. Switching to .bmp buys you dead-simple structure with no decoding step at all, which is why it is the better fit for quick lossless dumps from code, since a writer takes minutes to implement. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
JPG vs BMP at a glance
| Aspect | JPEG image (.jpg) | Bitmap image (.bmp) |
|---|---|---|
| Format type | Lossy — discards detail it judges invisible to shrink files | Lossless — every pixel or sample is preserved exactly |
| How it stores data | compresses 8x8 pixel blocks with a discrete cosine transform followed by quantization, which is where detail is discarded | pixels are typically stored uncompressed; optional RLE encoding exists only for 4-bit and 8-bit palette images |
| Strongest at | publishing photographs on websites where file size and universal support matter | quick lossless dumps from code, since a writer takes minutes to implement |
| Weak spot | every re-save re-compresses the image, so quality erodes across editing generations | no effective compression, so files dwarf PNG equivalents of the same image |
Pick BMP as the output
Select .bmp in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if BMP is selectable, the route is real and validated.
Convert on your device
Press Convert. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid BMP file. Outputs keep the original filename with the .bmp extension.
JPG to BMP questions, answered
Will converting JPG to BMP lose quality?
No new loss is introduced — since jpg is lossy-oriented and bmp is lossless-oriented, everything the .jpg file still contains is carried over exactly. What was already discarded by the original lossy encode cannot be recovered, though; converting to .bmp does not "restore" quality.
Is it private to convert JPG files here?
Yes — the .jpg file is processed inside your browser tab and never uploaded. Decoding and re-encoding happen on your device using the browser's native image pipeline and hand-tuned encoders. Close the tab and the file is gone from memory.
Where will the BMP file work?
Windows treats BMP as a native citizen, and macOS, Linux, and all major browsers open it without complaint. The format's problem is never support but waste: emailing or hosting uncompressed bitmaps burns bandwidth for zero benefit, so converting to PNG is almost always an upgrade.
Will the BMP file be bigger or smaller than my JPG?
Larger, sometimes much larger. A lossless .bmp must store every pixel or sample the decoder produced, without the perceptual shortcuts .jpg used. Use this route for editing headroom, not for saving space.
What happens to the metadata in my JPG file?
In .jpg, carries EXIF (camera settings, GPS, orientation), XMP, and IPTC records in APPn marker segments, plus embedded ICC color profiles and thumbnails. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
Can I convert BMP back to JPG?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .jpg → .bmp → .jpg is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
