Convert images to JPG format with customizable quality settings.
Convert any image format (PNG, GIF, WebP, BMP, TIFF, etc.) to JPG format with customizable quality settings. Perfect for web optimization, reducing file sizes, creating compatible images, and standardizing image formats across projects. This tool gives you precise control over compression quality, allowing you to balance file size with image clarity for any use case.
JPG (JPEG) is the most widely used image format for photos and complex images. Key characteristics include:
| Format | Best For | File Size | Transparency |
|---|---|---|---|
| JPG | Photographs, complex images | Very Small | No |
| PNG | Graphics, logos, transparency needed | Medium-Large | Yes |
| GIF | Simple graphics, animations | Small | Yes |
| WebP | Web optimization, modern browsers | Very Small | Yes |
| TIFF | Professional printing, archiving | Very Large | Yes |
100% Quality: Maximum quality with largest file size. Every pixel detail preserved. Use for archival, printing, or when file size not important. Typical file size: Original dimensions unchanged.
90% Quality: Excellent quality with good compression. Imperceptible quality loss to human eye. Recommended for most uses. File size reduced 30-50%.
80% Quality: Very good quality suitable for web. Minor compression artifacts visible only on close inspection. File size reduced 60-70%. Standard web quality.
70% Quality: Good balance between quality and file size. Some visible compression artifacts. File size reduced 75-80%. Acceptable for thumbnails and web.
50% Quality: Noticeable quality loss but acceptable for casual viewing. File size reduced 85-90%. Use only when file size critical.
Web Optimization: Convert PNG/GIF photos to JPG for faster page loading. JPG at 80-85% quality provides excellent quality with 50% smaller file sizes.
Email Attachments: Convert large images to JPG to stay within email size limits while maintaining acceptable quality.
Social Media: Convert images to JPG for faster uploads and smaller storage requirements on social platforms.
Standardization: Convert all project images to consistent JPG format for compatibility and consistency.
Print Preparation: Convert to JPG if printer or publishing system requires JPG format specifically.
Legacy System Compatibility: Convert modern formats (WebP, HEIC) to universal JPG for systems that don't support newer formats.
JPG uses lossy compression, meaning some image data is permanently removed. This is imperceptible at high quality settings but becomes visible at lower qualities. Photographic images handle compression better than graphics or text. Once converted, quality loss is permanent - re-compressing worsens image further.
Yes, if the PNG has transparency or crisp graphics. PNG's lossless compression is replaced with JPG's lossy compression. However, for photographs, quality loss is imperceptible at 85%+ quality. Transparency is lost (replaced with solid color or white background).
For web: 75-85%. For email: 70-80%. For printing: 90-100%. For thumbnails: 60-75%. Start at 85% and adjust based on your needs and file size requirements.
Yes, to re-compress for smaller file size. However, every compression cycle degrades quality. Always keep original high-quality version and compress from that, not from already-compressed JPG.
File size reduction depends on source format and quality. PNG photographs convert to 30-50% smaller JPG. Transparent PNGs lose transparency (requires background color added). Typical 85% quality web JPG is 20-30% original size.
