Why Convert Image Formats?

Different formats serve different purposes. JPG/JPEG is great for photographs because it gives a small file size with good quality. PNG is perfect for logos and screenshots because it supports transparent backgrounds. WebP is a modern format that provides even smaller files while keeping high quality (perfect for websites). BMP is an old, uncompressed format useful for some professional software. Our converter lets you switch between all of them instantly, without installing any apps.

📌 Frequently Asked Questions

🔒 Is my image private? +

Absolutely. The conversion uses the Canvas API directly inside your web browser. Your image never leaves your device. You can even disconnect from the internet after the page loads and the tool will still function.

🖼️ Will it keep the transparent background? +

If you convert to PNG or WebP, yes – transparency is preserved. If you convert to JPG or BMP, any transparent areas will automatically become a solid white background (since those formats do not support transparency).

📏 Is there a file size limit? +

There is no hard limit set by our tool, but very large images (greater than 20MB) may slow down your browser or cause it to crash depending on your device's memory.
