| Transparency | No | No |
| Animation | No | No |
| Colors | Usually 24-bit color, stored uncompressed | 8 bits per channel (16.7 million colors) |
| File size (photos) | Very large | Small |
| Opens on | Windows and most image viewers; rarely accepted on the web | Everything: every browser, phone, computer, printer kiosk and photo app |
| Best for | Old Windows software, embedded devices and tools that need raw pixels | Photos you want to share, upload, email or print |
About BMP and JPG
What is BMP?
BMP is an old Windows format that usually stores every pixel uncompressed. A photo saved as BMP can be 10–20 times larger than the same JPG. Today it is mostly needed for legacy software, some printers, industrial machines and microcontroller displays.
- Simple, uncompressed and lossless
- Readable by old and embedded software
- Enormous files
- No useful transparency or metadata
- Not accepted by most websites
What is JPG?
JPG (or JPEG) is the most widely used image format in the world. It compresses photos by discarding detail the eye barely notices, so a 12-megapixel picture fits in 2–5 MB. The trade-off is that every re-save loses a little more quality, and it cannot store transparency.
- Opens absolutely everywhere
- Small files for photographs
- Adjustable quality vs. size
- Lossy: quality drops a little with every re-save
- No transparency
- Blurry edges on text, logos and screenshots
Why GlideConvert?
- Private by design. Your files are converted on your own device by your browser — they are never uploaded to a server. That keeps them private, avoids upload waits and means there is no queue.
- Fast. Images convert in a fraction of a second; video uses your device’s hardware encoder.
- Free. No sign-up, no watermark. 10 images, 5 audio files or one video at a time — Pro lifts the limits and removes ads.
Frequently asked questions
Will converting BMP to JPG reduce quality?
JPG uses lossy compression, but at the default quality of 90% the difference is practically invisible. Move the quality slider down for smaller files, or up to 100% for the best possible result.
Will the JPG file be smaller than the BMP?
Usually yes — JPG compresses photos more efficiently than BMP. The exact saving depends on the image and the quality you choose.
What JPG quality should I choose?
90% (the default) looks identical to the original for almost any photo. 75–85% gives noticeably smaller files with hardly visible differences. Use 95–100% only if you plan to edit the image further.
Can I convert several BMP images at once?
Yes. The free plan handles 10 images at a time, and you can download everything as a single ZIP. Pro removes the batch limit, converts files in parallel and supports files up to 4 GB.
Are my files uploaded to a server?
No. GlideConvert runs entirely in your browser: images are processed with the browser’s built-in codecs and WebAssembly, video and audio with hardware-accelerated WebCodecs (or a WebAssembly build of FFmpeg for older formats). Nothing is sent anywhere — you can even disconnect from the internet once the page has loaded.
Does it work on iPhone, Android, Mac and Windows?
Yes. It works in any up-to-date browser — Chrome, Edge, Safari, Firefox or Samsung Internet — on phones, tablets and computers, with nothing to install. On phones, extremely large images may be scaled down to fit within the browser’s memory limit; you will see a note if that happens.
