Compress images to reduce file size. Drop one or multiple files, pick a quality preset, and download optimized versions with before/after comparison.
Compress images instantly in your browser — no uploads, no watermarks, no file limits. Drop one or multiple images, choose a quality preset (High, Medium, or Low), and download optimized files with a clear before/after size comparison. The Puma Image Compressor runs 100% client-side using the Canvas API. Your files never leave your device. Perfect for reducing image sizes before uploading to websites, email, or social media.
The compressor re-encodes your image at a lower quality setting using the Canvas API. When you export a JPG or WebP at 65% quality instead of 95%, the encoder discards visual data that most people can't see — resulting in a much smaller file that still looks great. PNG compression is lossless, so converting a PNG to JPG or WebP typically gives the biggest savings.
At High quality (85%), most images are visually indistinguishable from the original. Medium (65%) is good for web use — file sizes drop significantly with minimal visible difference. Low (40%) produces noticeably smaller files and is best for thumbnails or previews where file size matters more than sharpness.
Yes. Drag and drop or select multiple images at once. The compressor processes each file individually and shows before/after sizes for every image. A total savings summary appears at the bottom. Files download one at a time to keep things simple and avoid any browser zip library dependencies.
No. All compression happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device. This makes the tool safe for sensitive photos, client work, or proprietary images. Unlike TinyPNG or Compressor.io which upload your files to their servers, this tool processes everything locally.
