Image Converter — Convert PNG, JPG, WebP and More
An image converter lets you change images from one file format to another without losing quality or installing software. Whether you need to convert a PNG to JPG for a smaller file size, transform a JPG to WebP for faster website loading, or save a high-resolution image as a PNG with transparency, our browser-based converter handles it all.
Unlike online converters that upload your images to remote servers, this tool runs entirely in your browser using the HTML5 Canvas API. Your images never leave your computer — making it completely private, secure, and fast. There are no file size limits, no queues, and no registration required.
You can also resize images during conversion by setting custom width and height values while maintaining the original aspect ratio. A quality slider gives you fine-grained control over JPG and WebP output compression, balancing file size with visual fidelity.
How to Convert an Image
-
Upload your image Drag and drop an image file onto the upload area, or click to browse your computer. We support PNG, JPG, WebP, SVG, BMP, and GIF formats.
-
Choose the output format Select your desired format from the dropdown: PNG (lossless, supports transparency), JPG (smaller file size, good for photos), or WebP (modern format with superior compression).
-
Adjust settings Use the quality slider to control compression for JPG and WebP outputs. Optionally enter custom width and height values to resize the image. The aspect ratio lock keeps proportions intact.
-
Convert the image Click the "Convert" button to process your image. The conversion happens instantly in your browser using the Canvas API. A side-by-side preview shows the original and converted versions.
-
Download the result Review the converted preview and compare file sizes. When you're satisfied, click the "Download" button to save the converted image to your computer.
Frequently Asked Questions
No, never. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded, stored, or transmitted anywhere. This makes the converter completely private and secure — ideal for sensitive or personal images.
There are no artificial limits imposed by the tool. However, very large images (e.g., 20,000+ pixel dimensions) may cause performance issues in your browser's Canvas API since all processing is done in memory. For typical photos and web graphics, the converter handles them with ease.
PNG is a lossless format that supports transparency, making it ideal for logos, icons, and graphics with sharp edges. JPG is a lossy format that produces smaller file sizes, best for photographs and complex images. WebP is a modern format developed by Google that offers both lossless and lossy compression — typically 25-35% smaller file sizes than JPG at equivalent quality, with support for transparency.
Converting between lossless formats (PNG to PNG, BMP to PNG) preserves full quality. Converting to a lossy format like JPG or WebP may reduce quality depending on the compression level you choose — the quality slider lets you control this trade-off. We recommend setting quality to 90% for a good balance of file size and visual fidelity.
Yes! You can upload SVG (vector) files and convert them to PNG, JPG, or WebP raster formats. The SVG is rendered onto a canvas and then exported in your chosen format. Note that the output will be a raster image at the specified resolution, not a vector file.
