This tool runs entirely in your browser – no server uploads required. Add your images and click COMPRESS. The tool automatically analyzes each file and selects optimal compression settings. Once processing is complete, you can save the result immediately or use the comparison view to fine-tune quality with the slider. Each image can be adjusted individually before saving.
For JPEG files, the tool detects the original quality level from the file's quantization tables. The default target quality is 80, which provides an excellent balance between file size and visual quality for most images. You can use the slider to adjust this – higher values preserve more detail but result in larger files, while lower values create smaller files with more visible compression artifacts. For even smaller files, consider converting to WebP or AVIF.
PNG images are converted to PNG8 format with up to 256 colors. This format is ideal for web graphics, icons, logos, screenshots, and illustrations where color count is limited. Transparency is fully preserved. The Colors slider lets you reduce the palette further for additional compression.
If your PNG is a photograph or contains smooth gradients with many colors, PNG8 may not be suitable. In this case, convert your image to JPG or WebP for better results.
WebP images are compressed using lossy compression similar to JPEG. WebP typically achieves 25-35% smaller file sizes than JPEG at equivalent visual quality. The quality slider works the same way as for JPEG – adjust it to find the right balance for your needs.
Animated GIFs are optimized by analyzing and reducing the color palette while preserving animation frames. The Colors slider controls the maximum palette size from 2 to 256 colors. Reducing colors can dramatically decrease file size, especially for animations with simple graphics. For even better compression, consider converting GIF to WebP animation.
All image processing happens entirely in your browser using WebAssembly technology. There are no uploads to any server, no data collection, and no privacy concerns. All metadata (EXIF, GPS, camera info) is automatically removed from compressed images.
No registration required, no daily limits, no watermarks. Compress as many images as you need, completely free. The tool is designed for both casual users and professionals who need reliable, high-quality compression.
