Converting image formats is simple with this browser-based tool. Click or drag your images into the upload area, select your desired output format from the dropdown, adjust the quality slider for lossy formats like JPG and WebP, and press Convert All. The tool processes each image using the HTML5 Canvas API entirely on your device. No files are ever uploaded to a server, making this converter completely safe for personal photographs, confidential documents, and proprietary graphics. You can convert a single image or batch process dozens of files at once. Each converted image shows a preview with file size comparison so you can see exactly how much space you are saving.
JPG vs PNG vs WebP: Which Format to Choose
Choosing the right image format depends on what your image contains and where you plan to use it. JPG (JPEG) is ideal for photographs and complex images with gradients and many colors. It uses lossy compression, meaning it discards some data to achieve smaller file sizes, typically producing files 70 to 90 percent smaller than PNG. PNG uses lossless compression and supports transparency, making it the best choice for screenshots, logos, graphics with text, and images where pixel-perfect quality matters. WebP is a modern format developed by Google that supports both lossy and lossless compression, transparency, and animation. WebP files are typically 25 to 35 percent smaller than equivalent JPG files and 26 percent smaller than PNG files, making it the best all-around choice for web images. BMP is an uncompressed format used in Windows applications, while GIF supports simple animations and is limited to 256 colors. ICO is used specifically for website favicons and Windows application icons.

GIF: 256 colors, animation, simple graphics
BMP: Uncompressed, no quality loss, large files
ICO: Favicon format, multi-size container
Batch Converting Multiple Images
This tool supports batch conversion, letting you process multiple images simultaneously. Select all the files you want to convert, choose a target format, and the tool converts each image one by one with a progress indicator. After conversion, you can download each file individually or grab all converted images as a single ZIP archive. Batch conversion is especially useful when migrating a website from one image format to another, preparing product photographs for an e-commerce platform, optimizing a photo gallery for web delivery, or converting screenshots from PNG to a lighter format. The quality slider applies to all images in the batch, ensuring consistent output across your entire collection. For lossy formats like JPG and WebP, a quality setting of 85 to 92 is recommended for the best balance between visual fidelity and file size reduction.
Privacy and Security
All conversion happens entirely in your browser using the HTML5 Canvas API and JavaScript. Your files are never uploaded to any server and no data leaves your device. The tool works offline after the page loads, making it completely safe for sensitive images including personal photographs, medical records, legal documents, and proprietary business graphics.
