Supports: JPG, PNG, WebP, AVIF, GIF, BMP, HEIC • Batch processing supported
TL;DR
Convert images between JPG, PNG, WebP, AVIF, GIF, and BMP formats. Upload multiple images, select output format, adjust quality for lossy formats (JPEG, WebP, AVIF), and choose whether to preserve transparency. Batch process all images at once and download individually or as a ZIP archive.
How to Convert Image Formats
Change image formats while controlling quality and transparency.
Step-by-Step Guide
Step 1: Upload your images. Drag and drop one or more images, or click to browse. Supports JPG, PNG, WebP, AVIF, GIF, BMP, and HEIC formats.
Step 2: Select output format. Choose from JPG, PNG, WebP, AVIF, GIF, or BMP. Each format has different strengths for different use cases.
Step 3: Adjust quality (if available). For JPEG, WebP, and AVIF, use the quality slider (10-100%). Higher quality means larger files. PNG, GIF, and BMP don't use lossy compression.
Step 4: Set transparency option. For formats that support transparency (PNG, WebP, AVIF, GIF), choose whether to preserve transparent areas. Non-transparent formats use white backgrounds.
Step 5: Convert and download. Click "Convert" to process all images. Download each individually or get all as a ZIP file.
Understanding Image Formats
Choose the right format for your needs.
JPEG/JPG. Best for photographs. Lossy compression creates small files but doesn't support transparency. Quality 80-90% is usually good for web use.
PNG. Lossless compression preserves every pixel. Supports transparency. Best for graphics, logos, screenshots, and images with text. Larger files than JPEG.
WebP. Modern format with excellent compression. Supports both lossy and lossless modes, plus transparency. Smaller files than JPEG/PNG at similar quality. Wide browser support.
AVIF. Newest format with best compression ratios. Supports transparency and HDR. Smaller files than WebP but slower to encode. Growing browser support.
GIF. Limited to 256 colors but supports animation and transparency. Best for simple graphics and short animations. Not suitable for photographs.
BMP. Uncompressed bitmap format. Large files but no quality loss. Useful for Windows applications or when you need raw pixel data.
When to Convert Formats
Common reasons to change image formats.
Reduce file size. Convert PNG to JPEG or WebP for photographs. WebP can reduce file sizes by 25-35% compared to JPEG at similar quality.
Add transparency support. Convert JPEG to PNG or WebP when you need transparent backgrounds. Use the Background Remover first to create transparency.
Platform compatibility. Some platforms only accept certain formats. Convert to JPEG for universal support or WebP for modern web optimization.
Print preparation. Convert web images to high-quality formats for printing. PNG or high-quality JPEG work well for print.
Tips for Better Results
Get optimal quality and file size from conversions.
Start with high quality sources. Converting doesn't improve quality. Start with the highest quality original available.
Match format to content. Use JPEG/WebP for photos, PNG for graphics with hard edges, and GIF only for simple animations.
Test quality settings. For lossy formats, try 85% quality first. Compare file sizes at 80%, 85%, and 90% to find the best balance.
Consider your audience. AVIF has best compression but limited support in older browsers. WebP works in all modern browsers. JPEG is universal.
Frequently Asked Questions
Does converting formats reduce quality?
Converting to lossy formats (JPEG, WebP lossy, AVIF) does reduce quality each time. Converting to PNG is lossless but cannot restore quality already lost. Always keep original files.
Why is my converted file larger than the original?
This happens when converting to a less efficient format (e.g., JPEG to PNG) or when the source was already highly optimized. Try a different format or lower quality setting.
How do I preserve transparency?
Choose PNG, WebP, AVIF, or GIF as output format and enable 'Preserve Transparency'. JPEG and BMP don't support transparency—transparent areas become white.
What quality setting should I use?
For web use, 80-85% is usually optimal—small files with minimal visible quality loss. For archival or print, use 92-100%. Below 70%, quality degradation becomes noticeable.
Can I convert animated GIFs?
This tool converts still images. Animated GIFs will be converted as single-frame images, losing animation. Use a dedicated GIF tool for animations.
