2 tools · Compress and convert JPG, PNG and WebP images in your browser
Image optimization and format conversion are essential for any website or product that cares about performance. Unoptimized images are still the leading cause of slow page loads, and slow pages lose users before they reach your content. The tools in this section let you compress images without visible quality loss using modern compression algorithms, and convert between formats including JPEG, PNG, WebP, and more — all without leaving your browser. No file size limits imposed by a remote server. No upload queue. No waiting. Files are processed entirely on your device using browser Canvas APIs, so your images never leave your machine. This makes the tools safe to use with confidential images — client documents, internal screenshots, medical records, or any file you would not want stored on a third-party server. Both tools support multiple images in a single session so you can prepare an entire set of assets efficiently.
Frequently asked questions
How much can I compress an image without losing visible quality?
For JPEG and WebP formats, you can typically reduce file size by 40–70% with no perceptible quality loss at a quality setting between 75–85. For PNG files, lossless compression reduces size by 20–40% without any quality change. The optimal ratio depends on image content: photos with complex gradients compress differently than flat illustrations or icons with large areas of solid color.
What is the difference between JPEG, PNG, and WebP?
JPEG is a lossy format ideal for photographs and complex images with many colors — it produces small file sizes but discards some information on each save. PNG is lossless and preserves every pixel, making it right for screenshots, logos, and images with text or sharp edges, though file sizes are larger. WebP is a modern format combining lossy and lossless modes that achieves 25–35% smaller files than JPEG or PNG at equivalent quality. All major browsers released after 2020 support WebP.
Does the image processing happen on my device or on a server?
All processing happens entirely on your device using the browser's Canvas API. Your image files are never uploaded to any server, making the tools safe for confidential images such as client documents, internal screenshots, or medical records. Nothing you process is stored or logged anywhere outside your own browser session.
Can I convert animated GIFs?
The image converter handles static formats: JPEG, PNG, WebP, and BMP. It does not process animated GIFs or video files. If you need to convert an animated GIF to WebP animation or extract individual frames, a dedicated video or animation tool is required for those workflows.
