Image Converter
Convert images to JPG, PNG, WebP, or AVIF. Upload an image, choose the output format, adjust quality, and optionally resize.
100% Client-Side Processing
Most formats convert in your browser. HEIC/HEIF requires server-side conversion; those files are uploaded temporarily for processing and then deleted.
Supported formats: JPG/JPEG, PNG, WebP, GIF (static only), AVIF, HEIC/HEIF, SVG (rasterized). Recommended: up to 20MB per image. Maximum: ~50MB. Maximum image size: 8192×8192 pixels (most formats); HEIC/HEIF: 4096×4096 pixels

What is image conversion?
Image conversion changes an image file from one format to another for compatibility, performance, or editing workflows.
Use the format guide below to pick the best output type for photos, transparency, or modern web performance.
How it Works
- Upload an image.
- Choose an output format (JPG, PNG, WebP, or AVIF).
- Adjust quality and optionally resize.
- Download the result.
Conversion Settings
Output format
Pick JPG, PNG, WebP, or AVIF. If you pick JPG, any transparency will be flattened using your chosen background color.
Quality (JPG/WebP/AVIF)
Higher quality preserves more detail but increases file size. For most web photos, 70–85% is a great range.
Maximum width
Resize while keeping aspect ratio. This is often the fastest way to reduce file size.
Which Format Should I Use?
JPG/JPEG
Best for photos and images with lots of colors
- Universal compatibility (works everywhere)
- Great compression for photos
- No transparency support
- Lossy: loses quality with each save
PNG
Best for graphics, logos, and images needing transparency
- Supports transparency
- Lossless (no quality loss)
- Larger file sizes than JPG
- Not ideal for photos
WebP
Best for modern websites (great balance)
- 25-35% smaller than JPG at same quality
- Supports transparency
- Good for both photos and graphics
- Not supported in very old browsers (IE11)
AVIF
Best for cutting-edge web performance
- 30-50% smaller than JPG at same quality
- Supports transparency
- Next-generation format
- Limited browser support (2020+)

- Transparency: convert to PNG/WebP/AVIF when you need an alpha channel.
- Modern web: convert to WebP/AVIF for smaller files and faster pages.
Frequently Asked Questions
Most formats convert in your browser. HEIC/HEIF requires server-side conversion because browsers typically can’t decode it natively.
This can happen when converting from a lossy format (like JPG) to a lossless format (like PNG), or when using high quality settings. Try WebP/AVIF for photos, lower quality, and/or resize.
