Free Image Format Converter – JPG, PNG, WebP, BMP

Welcome to PureDoc's Image Format Converter – the only tool you need to change any image from one format to another. Whether you have a photo that must be a PNG, or a logo that needs to be a JPG, this tool does it all. And because everything runs in your browser, your images never get uploaded to any server. Your privacy is fully protected.

Why Convert Image Formats?

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

💡 Format Recommendations

JPEG: Use for photos, realistic images, or when file size matters. PNG: Use for logos, icons, screenshots, or when you need transparent background. WebP: Use for modern websites – smaller files than JPEG with similar quality. BMP: Only use if a specific software demands it (file will be huge).

📌 Frequently Asked Questions

🔒 Is my image private? ▼

Absolutely. The conversion uses canvas API inside your browser. Your image never leaves your device. You can even disconnect from the internet after the page loads.

🖼️ Will it keep transparency? ▼

If you convert to PNG, yes – transparency is preserved. If you convert to JPG, transparency will become white background (JPG doesn't support transparency).

📏 Is there a file size limit? ▼

No hard limit, but very large images (>50MB) may slow down your browser. For best results, keep under 20MB.

📱 Does it work on mobile? ▼

Yes, fully responsive. Works on iPhones, Android phones, tablets, and desktops.
