1Upload your BMP images and wait for the preview to appear.
2Pick a crop preset: 1:1, 16:9 or 4:3 cuts the largest centred area of that shape, and Free Crop keeps the whole picture.
3Start the crop and wait for the result.
4Download the cropped BMP file, with everything outside the frame discarded.
Crop BMP FAQ
What is the most common mistake when cropping BMP images?
+
Cropping before resizing. Crop first from the full-resolution original, then resize the result — doing it the other way round means the region you keep has already lost detail it did not need to lose.
Can I crop several files to the same region at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Can I run Crop BMP on several BMP images at once?
+
Yes — upload the set and they process in parallel under one set of settings. Lossless files are larger, so a big batch is bound by your upload speed rather than by the processing itself.
Does Crop BMP cost anything?
+
No. Crop BMP is free without an account and adds no watermark. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
Does Crop BMP belong on a site about a photo format?
+
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. Crop BMP runs on the same upload and the same account as the conversions because that is where those jobs land.
What is the sensible next step after Crop BMP?
+
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Is this the same engine as the other converter sites?
+
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Is anything kept, and do I need to sign in?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
