Free Online Image Format Converter
Convert images between the most common web and design formats — JPG, PNG, WebP, BMP, GIF, SVG and ICO — directly in your browser. Drag and drop multiple files at once, apply quality settings and optional resize, then download individually or as a ZIP. No server upload, no account, no watermarks.
Why convert to WebP?
WebP is Google's modern image format that delivers 25–35% smaller file sizes compared to JPEG and PNG at the same visual quality. Converting your site's images to WebP significantly improves page load speed and Core Web Vitals scores, making it the most impactful conversion for web developers and designers.
PNG to ICO — favicon generator
Need a .ico favicon? Drop any PNG or other image, select ICO as the target format, set Max Width to 32 pixels, and convert. The ICO file is built in pure JavaScript — no third-party libraries, instant download.
Batch conversion with quality control
Drop multiple images at once and convert them all in a single click. The quality slider controls compression for JPG and WebP output (1–100, default 85). PNG and BMP are always lossless. Use the resize inputs to cap image dimensions — useful for reducing large photos to web-friendly sizes while keeping the aspect ratio intact.
SVG and GIF support
SVG files are rasterized to the target format using the browser's native SVG renderer. For GIF files, only the first frame is converted (animated GIF conversion is not supported by browser Canvas). A note is shown in the UI to clarify this limitation.
Frequently asked questions
Which image formats are supported?
Input: JPG, PNG, WebP, BMP, GIF (first frame) and SVG. Output: JPG, PNG, WebP, BMP and ICO. All conversion is done using the browser's Canvas API — no server involved.
How do I convert JPG to WebP?
Drop or select your JPG files, choose WebP as the target format, adjust quality (default 85 is a good balance), and click Convert All. Download individual files or all at once as a ZIP.
Can I convert multiple images at once?
Yes. Drag and drop multiple files at once. Convert all with one click and download a ZIP archive containing all converted images.
How do I make an ICO file from a PNG?
Drop your PNG, select ICO as the target format, optionally set Max Width to 32 or 64 pixels, and click Convert All. The ICO encoder is built with pure JavaScript — no external libraries needed.
Does this tool upload my images?
Never. All conversion happens locally in your browser using the Canvas API. Your images are never transmitted to any server.
Why is the WebP file larger than the original?
This can happen with small images, images that are already heavily compressed, or when converting from a very small PNG. Try increasing the quality slider slightly or stick to PNG for small graphics. For photos and complex images, WebP is typically 25–40% smaller.
