Frequently asked questions
Why convert BMP?
BMP is a very old uncompressed format. Modern uses almost universally prefer JPG (smaller, same quality) or PNG (smaller, lossless). Converting BMP to JPG often produces files 10-20x smaller.
Can I convert multiple BMPs at once?
Yes. Drop as many as you like — they're processed in parallel.
Are my files really not uploaded?
Correct. Every conversion in this tool runs in your browser using JavaScript and the local file APIs. There is no server-side processing, no file upload, no temporary storage, and no log of what you converted. You can verify this by opening your browser's network tab while converting — the only traffic is loading the page itself.
Do I need an account or to install anything?
No. Open the page, drop your file, download the result. No signup, no email, no extension, no app.
Is there a file-size limit?
Not from us. The practical limit is your device's memory — browser tabs typically handle files in the hundreds of megabytes range without issues. Very large files may take longer to process on phones than on laptops.
