Settings information
3 settings
Every control in BMP to JPG, explained — what it does and when to use it.
Settings
- JPEG qualitySliderRange: 20–100 · Default: 90
- Sets the JPEG compression level — higher keeps more detail but makes a bigger file; 90 is a high-quality default and 60–80 suits most photos.
- Background fillColor picker
- Chooses the color that fills transparent areas of the source image, since JPG cannot store transparency — white by default; match it to your page or brand background if needed.
Mode
- Single file / BatchDropdown
- Switches between converting one file at a time and batch mode, which converts many files with the same settings and downloads them together as a single ZIP.Options: Single fileBatch

Try it nowFrequently Asked Questions
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.
qualityJPEG 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.
technicalYes, 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.
featuresSince 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.
tipsYes — 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.
featuresYes — 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.
