BMP to JPG Converter — Convert BMP to JPG Free Online

The Quality slider runs from 20 to 100; keep it near 90 (the default) for photos where you want the file size cut dramatically with almost no visible loss versus the uncompressed BMP. Drop it to 60–75 for screenshots or web thumbnails where a smaller file matters more than pixel-perfect detail.

JPEG itself can't store an alpha channel, so the tool always includes a Background fill color swatch — white by default — that gets applied to any transparent pixels before the file is flattened. It matters most for 32-bit BMPs that do carry alpha data; change the swatch if you need the fill to match a specific page or brand background instead of white.

Yes, using Batch mode. Toggle from Single file to Batch, drop in multiple BMP files, and the same Quality and Background fill settings you've set are applied to every file, which are then bundled into one ZIP — this is a Premium feature, so free accounts convert one BMP at a time.

Since BMP screenshots are already opaque and mostly flat color, set Quality to around 70–80 (plenty of fidelity for UI captures) and leave Background fill on white, then switch to Batch mode to convert the whole folder into a single downloadable ZIP in one pass instead of repeating the conversion file by file.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 files on Premium or 200 on Pro, set your options once, and every file is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 files on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking image gets refused.

Two things to check. First, what the receiving app actually accepts — plenty of upload forms say "images" and mean JPG only. Second, whether the file really is what its name claims: renaming a HEIC to .jpg does not convert anything, and that single mistake is the most common reason a "converted" file is still rejected. Run the real conversion and the extension will match the contents.

BMP to JPG supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Premium supports batches of up to 60 files, with the applicable plan limits shown before processing.

No — BMP to JPG runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.

A BMP stores color for every pixel without compression, so the size grows with the pixel count, about 3 bytes per pixel for a standard 24-bit bitmap. A JPG discards detail the eye is least likely to notice, which is why it is so much smaller.

Many email clients, web forms and messaging apps accept JPG and PNG but not BMP, so a bitmap from Paint or an older program gets refused. A JPG made here is accepted by far more programs and forms.

A little, because JPG is lossy and BMP is not. At 90 the difference is hard to see in photos, and sharp text and thin lines show it first. For an exact copy, open the Output format list and choose PNG, which is lossless and usually much smaller than a BMP.

Yes. Only the file format and size change, not the pixel dimensions. If you need a different size, resize the picture before or after converting.

Yes. A bitmap from Paint, an old scanner or a screenshot tool is an ordinary .bmp file, and this page opens it. Choose the file, set the quality and convert.
