BMP is uncompressed — the same picture as JPG is typically 10–20× smaller. JPG is lossy, so keep your original BMP as the master copy.

How to convert BMP to JPG without uploading it
- Drop your BMP files above — or paste one straight from your clipboard. You can add up to 20 at once.
- Set JPG quality (85 is a good default), pick a width (800 px by default, never upscaled), and optionally a destination size so the JPG fits under an upload limit.
- Download each file, or grab everything as one ZIP. Your originals are untouched and your file data never leaves your device.
Why convert BMP at all?
BMP is the format Windows Paint and many scanners save by default — and it stores every pixel in full, with no compression at all. A BMP screenshot that is 15 MB as a BMP is typically under 1 MB as a JPG at 85% quality, with no visible difference. Email clients, upload forms, Discord, Slack and most websites either refuse BMP or cap it, so converting first is what makes the file shareable.
Honest limitations
- JPG is lossy — every conversion discards some detail, and a BMP is already pixels: converting adds no quality, it only removes size. Keep the original BMP as your master copy.
- BMP is uncompressed, so output is typically 10–20× smaller — but that is typical, never a guarantee: a tiny paletted BMP of flat colours can come out larger as a JPG, and the tool says so on the file instead of hiding it.
- 32-bit alpha is flattened — JPG has no transparency, so transparent pixels in a 32-bit BMP are flattened onto the background colour you choose.
- RLE-compressed BMPs are unsupported — a few old apps saved BMPs with RLE8 or RLE4 compression. This tool refuses them with a clear message; re-save uncompressed (24-bit BMP in Paint) and try again.
- EXIF/metadata is dropped — BMP has none to keep. BMP carries no camera settings, location or orientation, so there is nothing to preserve and nothing to rotate; the pixels are converted exactly as stored.
- Estimates are estimates — the size shown while converting is a rough model; the real size is shown once conversion finishes.
Frequently asked questions
How can I convert BMP to JPG without uploading it anywhere?
This converter runs entirely in your browser: it decodes your BMP with a pure JavaScript decoder built into the page and re-encodes it as JPG on a canvas. Your file data never leaves your device — the only third-party requests are the site's own analytics, which load at page open and never see your files. Verify it in the Network tab while it works.
Why is my BMP file so large?
BMP is an uncompressed format — every pixel is stored in full, so a BMP is typically 10–20 times larger than the same image as JPG. Converting to JPG at 85% quality keeps the picture looking the same while shrinking it dramatically, which is why BMPs are worth converting before emailing, uploading or sharing.
Does converting BMP to JPG reduce quality?
JPG is lossy: every conversion discards some image detail, and a BMP is already pixels — converting adds no quality, it only removes size. At 85% quality most photos and screenshots look identical to the original; use 90–100% for images you will edit further, and keep the original BMP as your master copy.
What happens to transparency when I convert BMP to JPG?
JPG has no transparency, so any transparent pixels in a 32-bit BMP are flattened onto a solid colour you choose — white by default, black, or any custom colour — and each converted file is marked when flattening happened. Keep the BMP if you need the transparent background.
What BMP files can this converter not open?
RLE-compressed BMPs (RLE8 and RLE4) are not supported — most BMPs are uncompressed, but a few old apps saved them compressed, and this tool tells you plainly instead of failing silently. Files that are only named .bmp but are really PNG, JPG or GIF are also refused with a clear message. Corrupt, empty and oversized files are refused the same way.
Does converting strip EXIF data or change orientation?
BMP carries no EXIF metadata at all — no camera settings, no location, no orientation tag — so there is nothing to keep and nothing to rotate. The pixels are converted exactly as stored, and the output JPG is stored upright as decoded.
Can I make the JPG fit under an upload limit?
Yes — pick a destination preset (website hero aims for under 300 KB, blog image under 150 KB, Discord or forum under 256 KB) and the converter retries with smaller width and lower quality until it fits, or reports the smallest size it could reach. A target is an aim, never a guarantee — the tool reports the size it actually reached on each file.
Is there a file size or daily limit?
No daily limit, no account. A 25 MB cap per file and 20 files per batch apply, because browsers cannot safely hold larger images in memory.
