Convert BMP to JPG
Convert bulky BMP bitmaps into compact JPGs — often 10–50× smaller — entirely in your browser. Perfect for old scans and legacy Windows exports.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Why BMP files are so huge
BMP is essentially raw pixels with a header — no compression at all. A single 10-megapixel scan stored as BMP weighs about 30 MB; the same image as a high-quality JPG is under 2 MB. BMPs mostly come from old scanners, legacy Windows software and medical or industrial exports, and converting them is the single biggest space win in image work.
Nothing visible is lost
At high quality settings the JPG re-encode of a scan or photo is visually indistinguishable from the raw bitmap — the 95% size reduction comes from compressing redundancy, not destroying detail. For line art or documents where absolute fidelity matters, the BMP to PNG converter keeps it lossless instead.
Batch through an archive locally
Old scan folders tend to hold hundreds of BMPs. Drop them all in — your browser converts the lot without uploading a byte, and hands back a ZIP.
Frequently asked questions
- Which formats are supported?
- You can convert to and from JPG, PNG, WebP, AVIF and BMP, and convert from HEIC/HEIF (iPhone photos). Browsers cannot create HEIC files, so HEIC is input-only. Output formats your browser cannot encode are detected and disabled automatically.
- Can I convert HEIC to JPG?
- Yes. Drop in a HEIC photo from an iPhone and choose JPG (or PNG/WebP). The HEIC file is decoded locally in your browser with a bundled decoder — it is never uploaded anywhere.
- Is transparency preserved?
- Yes, when converting to a format that supports an alpha channel (PNG, WebP, AVIF). For formats without transparency (JPG, BMP), you can pick a background color for transparent areas.
- Is my image uploaded?
- No. Conversion runs entirely in your browser — your images never touch a server.
- What is AVIF and should I use it?
- AVIF produces the smallest high-quality files. Encoding support varies by browser, so PixelVault enables it only when your browser can create AVIF files.
- Can I convert many images at once?
- Yes. Batch-convert a whole folder of images and export them together as a ZIP.
