Image Format Comparison Guide
Understanding when to use each image format helps you choose the right format for every situation.
Uncompressed, lossless format. Produces very large files — a 1MP BMP can be 3MB. Used in Windows system graphics and some legacy applications. No web browser support concerns it.
Lossy compressed format. Best for photographs and complex images. Typically 10-50x smaller than BMP. Supported by every browser, device, and platform. Ideal for sharing and web use.
Lossless compressed format that supports transparency. Larger than JPG but no quality loss. Best for logos, illustrations, screenshots, and any image where text or sharp edges matter.
Modern Google format that offers better compression than JPG with similar quality. 25-35% smaller than JPG. Supported by all modern browsers. Ideal for website performance optimization.
Supports animation and transparency with limited 256-color palette. Best for simple animations and small graphics. Static GIFs should be converted to PNG for better quality and size.
Use JPG for photographs, social media images, email attachments, and any image where file size matters more than pixel-perfect accuracy. 85-90% quality is the sweet spot.

Frequently Asked Questions
Why is BMP so much larger than JPG?
BMP stores every pixel's color data with no compression — a 1920x1080 BMP is about 6MB. JPG uses lossy compression that analyzes the image and discards data imperceptible to the human eye, producing files 10-50x smaller. At 90% quality, the difference between BMP and JPG is nearly invisible.
Does converting BMP to JPG lose quality?
Yes, JPG is a lossy format so some data is discarded. At 90% quality the loss is nearly imperceptible to the human eye. At 100% quality, the loss is minimal. For images requiring perfect fidelity — like medical images or technical diagrams — convert to PNG instead, which is lossless.
Can I also convert PNG, GIF, or WebP to JPG?
Yes. This tool converts any image format your browser can read — including PNG, GIF, WebP, and BMP — to JPG, PNG, or WebP format. Just upload your image and choose the output format.
Why does the background fill option matter?
JPG does not support transparency. If you convert a PNG or GIF image that has transparent areas, those transparent pixels need to be filled with a color. White is the most common fill for documents and photos. Choose Black for dark-themed images.
Is there a file size limit?
There is no hard limit, but very large images (above 20MB or very high resolution) may process slowly depending on your device's memory and processing speed. The tool works best with standard image sizes up to about 10MB.
Is my image sent to a server?
No. All conversion happens entirely in your browser using the HTML5 Canvas API. Your image never leaves your device and is never stored, shared, or accessible to anyone else.
