Your files stay private
This BMP converter runs entirely in your browser. When you drop a file, it stays on your device—we never upload it to our servers, store a copy, or open it on our side. We cannot see what is inside your BMP, and refreshing or closing the page clears everything from memory instantly. No account is required to convert.
Note: like most websites, we may use cookies for ads and analytics on public pages. That is separate from your document—those scripts never receive your file contents.
What is BMP?
BMP is the classic Windows bitmap format. It is uncompressed or lightly compressed, so files are often large. Older Windows apps, some scanners, and legacy screenshots still export .bmp. Modern browsers and CMS uploads usually prefer PNG or JPG instead.
What is PNG?
PNG is widely supported for graphics, screenshots, and web assets. It compresses better than BMP for many images and is accepted almost everywhere BMP is rejected. For photos where file size matters more than lossless detail, JPG may be smaller.
Why convert BMP to PNG
You convert BMP to PNG when a website won’t accept .bmp, when you need a smaller shareable file from a Paint export, or when a design tool expects PNG. Doing it in-browser means you are not uploading screenshots or documents to a third-party host. Practical notes for BMP to PNG: treat BMP as your working source whenever you still need to edit, and treat PNG as the distribution format you hand to other people or upload into picky systems. Before you convert, confirm you are allowed to transform the file—especially for ebooks, photos of IDs, and client work covered by an NDA. After conversion, open the PNG output once on the same device you will use to share it; catch rotation, cropping, or missing pages early. If something looks wrong, revisit the source BMP: password locks, rare codecs, animated frames, or scanned pages without OCR explain most failures. For repeat jobs, keep a small checklist—file size under the free limit, orientation fixed, sensitive metadata removed, and a clear filename with the PNG extension. This bmp to png converter flow is meant for everyday private conversions in the browser, not for guaranteed print-shop color management or courtroom-grade forensics. When you outgrow the free daily allowance, Pro simply raises limits; it does not change the browser-local privacy model for this tool. Finally, prefer descriptive downloads such as “invoice-march.png” over generic names so you can find the right PNG later without reopening every file. If you convert the same BMP repeatedly while iterating on design or copy, keep a dated folder of PNG outputs so you can roll back when a stakeholder prefers an earlier version. Small habits like these matter more than chasing mythical “perfect” conversion settings for everyday BMP to PNG jobs. When in doubt, convert a sample page or image first, then run the full batch once you like the result.
Tips for best results
- Prefer PNG when you need sharp UI text or plan to edit further.
- BMP files can be large — stay within the free size limit per file.
- For photo-like BMPs where size matters, try BMP to JPG instead.
- Check dimensions after download for print or retina use.
- Stay within free size and daily conversion limits.
Frequently asked questions
Is BMP to PNG free?
Yes, with free daily conversions and no watermark. Pro raises limits.
Do you upload my BMP files?
No. Conversion runs in your browser. Files are not uploaded for this tool.
Why convert BMP instead of renaming?
BMP pixel data is not the same as PNG. Converting encodes a real PNG that sites and apps expect.
Will my PNG be smaller?
Often yes — PNG compresses better than uncompressed BMP, though results vary by image.
Can I convert on mobile?
Yes, in a modern mobile browser that can decode BMP.
What limits apply?
Free tier follows the MB and daily caps on the tool page.
Is it safe to convert BMP files here?
Yes for privacy of your document: conversion runs in your browser. Your BMP file is not uploaded to our servers for conversion, and we do not store or read it. Refreshing or closing the page clears it. The website may still use cookies for ads and analytics, which is separate from your file.
Do you store or read my files?
No. For browser-based tools we never receive your file contents. Quota checks only count how many conversions you run.
