Converting between image formats is useful in various scenarios:
Convert images to WebP format for better web performance and faster loading times. WebP offers 25-35% smaller file sizes compared to JPG/PNG while maintaining quality.
Convert HEIC images (iPhone default format) to JPG or PNG for wider compatibility across devices and platforms.
Reduce file sizes by converting BMP (uncompressed) to compressed formats like JPG or WebP, saving significant storage space.
Convert JPG to PNG for lossless editing and preservation of image quality, especially for graphics with text or sharp edges.
Convert images to PNG or WebP when you need alpha channel (transparency) support, which JPG doesn't provide.
Convert to JPG for universal compatibility and easy sharing across all platforms and applications.
Different image formats serve different purposes. Here's a comprehensive guide to help you choose the right format:
Uncompressed raster image format developed by Microsoft. Produces large files but maintains perfect quality. Best for: archival, editing, when file size is not a concern.
Extension: .bmp, .dib | MIME: image/bmp | Compression: None | Transparency: No
Modern format used by Apple devices (iOS 11+). Offers better compression than JPG with similar quality. Based on HEVC video codec. Best for: iPhone photos, modern devices, storage efficiency.
Extension: .heic, .heif | MIME: image/heic | Compression: Lossy | Transparency: Yes
Most widely used image format. Lossy compression optimized for photographs. Best for: photos, web images, universal compatibility.
Extension: .jpg, .jpeg | MIME: image/jpeg | Compression: Lossy | Transparency: No
Lossless compression with transparency support. Ideal for graphics, logos, and images requiring sharp edges. Larger file sizes than JPG for photos. Best for: logos, graphics, screenshots, transparency.
Extension: .png | MIME: image/png | Compression: Lossless | Transparency: Yes
Modern format developed by Google. Supports both lossy and lossless compression, plus transparency. 25-35% smaller than JPG/PNG. Best for: web optimization, modern browsers, file size reduction.
Extension: .webp | MIME: image/webp | Compression: Both | Transparency: Yes
All image conversion happens entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security.
No server upload/download time. Conversion happens instantly in your browser, making it much faster than server-based converters.
Adjust quality settings to find the perfect balance between file size and visual quality for your specific needs.
No registration, no limitations, no watermarks. Convert as many images as you need, completely free.
Support for 5 major image formats: BMP, HEIC, JPG, PNG, and WebP. Convert between any formats with a single tool.
Works directly in your web browser. No software to download or install. Works on any device - desktop, tablet, or mobile.
Choose the right format for your needs:
Use JPG (80-85% quality) for general photos. Use WebP for web use (25-35% smaller). Avoid PNG for photos (much larger files).
Use PNG for graphics with text, logos, or sharp edges. PNG preserves quality perfectly and supports transparency.
Use WebP when possible (best compression). Provide JPG fallback for older browsers. Consider lazy loading for performance.
Convert HEIC to JPG for maximum compatibility when sharing. HEIC is great for storage on Apple devices but not widely supported elsewhere.
90% quality: Nearly identical to original, larger file. 80% quality: Excellent balance (recommended). 70% quality: Noticeable compression, smallest file.
Use PNG for lossless compression. WebP also supports lossless mode. Never convert JPG → PNG → JPG (quality loss from first conversion remains).
WebP is the best choice for web use, offering 25-35% smaller file sizes than JPG/PNG while maintaining excellent quality. However, for maximum compatibility with older browsers, JPG (80-85% quality) is a safe choice. Modern websites often use WebP with JPG fallback.
It depends on the formats and settings. Converting to lossless formats (PNG, lossless WebP) preserves quality perfectly. Converting to lossy formats (JPG, lossy WebP, HEIC) with high quality settings (85-90%) results in minimal visible quality loss. Lower quality settings reduce file size but also reduce image quality.
Yes, HEIC is fully supported. iPhone photos in HEIC format can be converted to JPG, PNG, or WebP for wider compatibility. HEIC offers excellent compression but is not widely supported outside Apple devices.
PNG uses lossless compression, which preserves all image data perfectly. For photographs, this results in larger files than JPG's lossy compression. PNG is best for graphics and logos, not photos. For photos, use JPG or WebP instead.
No, all image conversion happens entirely in your browser using JavaScript. Your images never leave your device, ensuring complete privacy and security. No server upload means faster conversion and guaranteed privacy.
Since conversion happens in your browser, the limit depends on your device's memory (RAM). Most devices can handle images up to 25MB comfortably. Very large images (50MB+) may require a desktop browser with sufficient RAM.
The current version processes one image at a time for optimal performance and privacy. For batch conversion, consider using the tool multiple times or desktop software designed for batch processing.
For most purposes, 80-85% quality provides an excellent balance between file size and visual quality. Use 90%+ for professional photography. Use 70-75% when file size is critical and slight quality reduction is acceptable. Experiment to find the sweet spot for your needs.
