Why Convert Image Formats?
Different formats serve different purposes: JPEG is ideal for photos, PNG preserves transparency, WebP offers superior compression, and BMP maintains raw quality. Convert to the right format to optimize file size, maintain quality, or ensure compatibility.

Frequently Asked Questions
Is my image uploaded to any server?
No. Everything happens locally in your browser. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
We support conversion between JPEG, PNG, WebP, and BMP formats. You can convert images individually or in batches of up to 20 files.
Can I convert multiple images at once?
Yes! Our batch conversion feature allows you to convert up to 20 images simultaneously. All files are processed locally in your browser for maximum privacy.
Will image quality be affected during conversion?
You have full control over the output quality. For lossy formats like JPEG and WebP, adjust the quality slider. PNG is lossless and preserves original quality. BMP maintains raw uncompressed quality.
What is the maximum file size?
Individual images can be up to 25MB each. Total batch size is limited to 100MB. For larger files, try resizing the image first using our Image Resizer tool.
Which format should I choose?
Use JPEG for photos and complex images. Choose PNG when you need transparency or lossless quality. WebP offers better compression than both. BMP is uncompressed and best for editing workflows.
