Why use a no-upload image compressor?
Most image compression tools upload your files to a server for processing. This compressor is different. It processes everything in your browser using the Canvas API. That means instant processing with no queue, complete privacy for sensitive screenshots or personal photos, and no file size limits beyond your browser's memory. There are no watermarks added to your output and no signup required.
The quality presets make it easy to find the right balance between file size and visual quality. The Low preset produces the smallest files, ideal for web thumbnails and email attachments. The High preset preserves most visual detail while still reducing file size significantly. The Lossless preset outputs the image at full quality in the selected format.
Supported formats
JPEG, PNG, WebP, GIF, BMP, TIFF, HEIC/HEIF (iPhone), and AVIF. Output can be JPEG, PNG, or WebP. Works with photos from phones, screenshots, design exports, and camera RAW previews. Compatible with Chrome, Firefox, Safari, and Edge.
Compress images for the web
Reduce image file sizes for faster page loads, better Core Web Vitals, and lower bandwidth costs. Perfect for blog posts, e-commerce product images, social media graphics, and email newsletters. The WebP output format delivers the best compression ratio for modern browsers. Compress a single hero image or batch-process an entire gallery. All without leaving your browser.
