About JPG and BMP
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
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
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 JPG to BMP reduce quality?
No. BMP is lossless, so the result looks exactly like your JPG. Converting cannot bring back detail the JPG compression already removed, though, and the BMP file will usually be bigger.
Will the BMP file be smaller than the JPG?
Usually not. BMP files keep every pixel, so they are typically larger than JPG. If you need a small file, try WebP or compress the image.
Which kind of BMP is created?
A standard 24-bit uncompressed Windows bitmap that every program able to read BMP can open.
Can I convert several JPG 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.
