📖 Image Format Guide
JPEG (.jpg) — Best for photographs. Lossy compression produces small files. Does not support transparency. Ideal for web photos, social media, and email.
PNG (.png) — Best for graphics, screenshots, and images with transparency. Lossless compression means larger files but perfect quality. Ideal for logos, icons, and UI elements.
WebP — Modern format by Google. Supports both lossy and lossless compression with transparency. Typically 25-35% smaller than JPEG/PNG. Ideal for web optimization.
BMP (.bmp) — Uncompressed bitmap format. Very large files but zero quality loss. Rarely used in modern workflows but useful for specific applications.
❓ Frequently Asked Questions
JPEG uses lossy compression, so there is some quality loss compared to PNG. We use 92% quality by default, which is visually indistinguishable from the original. Note that JPEG does not support transparency — transparent areas will be converted to white.
PNG and WebP support transparency. If you convert a transparent image to JPEG or BMP, transparent areas will be filled with white. To preserve transparency, use PNG or WebP format.
📖 What Is an Image Format Converter?
An image format converter transforms images between different file formats like PNG, JPEG, WebP, GIF, and BMP. Each format has specific advantages: JPEG for photographs with file size efficiency, PNG for images requiring transparency, WebP for modern web optimization, and GIF for simple animations.

💡 Tips & Best Practices
Format Guide: Use WebP for web (smallest size), PNG for logos/transparency, JPEG for photographs, and SVG for scalable graphics. WebP provides 25-35% smaller files than JPEG at equivalent quality.
