Your file: Processed in this browser tab — the file is not uploaded. Converted results are kept in this browser's local storage for up to two hours so their matching download page can show them; expired results are removed on the next site visit. Nothing is stored on our servers.
Good to know: Converting to JPG or lossy WebP applies the quality level you choose. JPG and BMP have no transparency, and our GIF encoder does not carry transparency either — transparent areas are flattened to the background for all three. Animated GIF input is read as its first frame.

Why convert BMP to JPG?

Scanners, screenshots from old software and industrial tools still produce uncompressed BMP files that are enormous. Converting to JPG keeps the visible quality while cutting the size by an order of magnitude, making the images practical to email, upload or archive.

What this tool preserves — and what it changes

✓ Preserved

The visible image at your chosen quality, at its original dimensions
Everything stays in the tab — no upload, even though scanner BMPs are often tens of megabytes

↺ Changed

File size drops by roughly an order of magnitude: BMP stores every pixel raw, JPEG compresses them at the slider value you set
The output is lossy — for diagrams and screenshots the BMP to PNG tool keeps edges cleaner

Known limits & edge cases

Huge scanner bitmaps can exceed the 100-megapixel processing cap — the tool says so explicitly instead of freezing the tab
A 'BMP' renamed from another format is identified by its content signature on the inspection card

About the formats

What is a BMP file?

BMP is an uncompressed raster format created by Microsoft for Windows. Every pixel is stored raw, so files are large but completely lossless and extremely simple to read, which is why old software, scanners, embedded devices and some industrial tools still produce or require BMP files. Converting BMP to JPG or PNG typically shrinks the file by 90% or more.

What is a JPG file?

JPG is the most widely used photo format on the web. It uses lossy compression that keeps file sizes small while preserving the detail that matters in photographs. Nearly every device, browser, app and website accepts JPG, which makes it the safest choice for sharing and uploading pictures. It does not support transparency or animation.

Taming the biggest files on your disk

BMP stores images with no compression at all — a plain grid of pixel values — so files coming out of old scanners, industrial cameras, medical devices and legacy Windows software are routinely tens of megabytes for a single picture. Converting to JPG shrinks a photographic BMP by 90–95% with no visible difference at the default quality, turning an unattachable file into an ordinary one.

This is mostly an archival and logistics move: scanned documents and old photo collections stored as BMP consume disk space and refuse to travel by email or upload form. Batch-convert the folder, spot-check a few results at 100% zoom, and keep the JPGs. If any of the images are line art or text scans headed for OCR or further processing, send those to PNG instead — lossless compression preserves hard edges better than JPG’s photographic model.

Frequently asked questions

Is this BMP to JPG converter free?

Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.

Can I convert multiple BMP files at once?

Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.

Will I lose quality converting BMP to JPG?

JPG uses lossy compression, so there is a quality/size trade-off you control with the quality slider. At the default 92% the difference is practically invisible while files stay small. For archival-grade copies choose PNG instead.
