📖 Format Guide
JPG
Best for photos. Lossy compression, small file sizes, no transparency.
PNG
Best for graphics & logos. Lossless, supports transparency (alpha channel).
WebP
Best for web. Superior compression vs JPG+PNG, supports transparency.
GIF
Best for simple graphics. 256 colours, supports animation.
BMP
Uncompressed raster. Large files, maximum compatibility with Windows apps.
💡 Tips
📦
Batch mode — drop as many images as you want. They all convert at once.
⚡
Converting PNG → WebP typically saves 25–35% file size with no visible quality loss.
🎨
Converting to JPG removes transparency. Use PNG or WebP to preserve alpha channels.
📐
Use the Resize option to scale all images to a max dimension while converting — great for batch thumbnails.
This image converter uses the HTML5 Canvas API to convert images between formats entirely in your browser. No files are uploaded to any server — the conversion happens locally on your device, making it fast, private, and available offline once the page is loaded.
The tool supports batch conversion — drop dozens of images at once and convert them all to your target format in seconds. Each file can be individually downloaded, or you can grab them all at once.

Frequently Asked Questions
No — converting from a lossy format (JPG) to a lossless one (PNG) does not recover lost quality. The compression artifacts from the JPG encoding are baked into the pixel data permanently. The resulting PNG will be larger and lossless, but it will still show the same artifacts as the original JPG. If quality matters, always work from the original uncompressed source.
Yes — JPG does not support transparency. When converting a PNG with a transparent background to JPG, this tool fills the transparent areas with white by default. If you need to preserve transparency, convert to WebP or keep it as PNG — both formats support alpha channels.
WebP is typically 25–35% smaller than equivalent-quality JPG and 50–80% smaller than PNG for photographs. For graphics with transparency, WebP is usually 25–40% smaller than PNG. The actual savings depend on the image content — photographic images with gradients see the biggest gains, while simple graphics with large flat-colour areas see smaller differences.
There's no hard limit — you can convert as many images as your device's memory allows. For large batches (50+ files), conversions are processed 4 at a time to avoid overwhelming the browser. Very large images (over 20 MP) may be slow to process on older devices.
Yes — SVG files are vector images that render at any resolution. When you convert an SVG to PNG or JPG, it is rasterized at its intrinsic dimensions (or your specified resize dimensions). If the SVG has no explicit dimensions, the browser may render it at a default size. You can use the Resize option to set a specific output pixel size.
