About BMP to JPG

BMP to JPG is the quickest way to deal with an oversized bitmap. BMP usually stores every pixel uncompressed, so images from old versions of Paint, legacy software, lab equipment or industrial cameras are huge for what they show. Many websites and chat apps don't accept BMP at all. Other formats that sites turn away, such as HEIC and WebP, have their own tools in Image Converter.

JPG compression brings the file down to a small fraction of its size. The single setting is Quality, 90 by default; lower it for an even lighter file, or keep it high for screenshots with text. The DPI stored in the BMP carries over, and the file keeps its original name with a .jpg ending.

How to use BMP to JPG

FAQ

BMP to JPG: questions and answers

Why are BMP files so large?
BMP usually saves every pixel without any compression. A full-screen image can take several megabytes as BMP but far less as JPG. Large PNG screenshots can be slimmed down the same way with PNG to JPG.
Will BMP to JPG change how the image looks?
Barely, at the default quality. JPG is lossy, so very fine detail and sharp text edges can soften at low settings; keep Quality at 90 or above for screenshots.
Is this BMP to JPG converter free, and how big can the file be?
Yes, with 2 conversions without an account and 2 per day with a free one, for files up to 50 MB. VIP has no daily limit and accepts bitmaps up to 1 GB.
Should I pick PNG instead of JPG for a BMP?
If the bitmap is a diagram, icon or screenshot with flat colors, PNG keeps it pixel-perfect. For photos, JPG gives the smaller file.
Is my BMP file stored after it's converted to JPG?
Only for an hour. The file is uploaded over HTTPS, converted in an isolated process and then deleted automatically. We don't share or sell uploads.
