Image Compressor
Dramatically reduce image file sizes while preserving visual quality using client-side Canvas API rendering with real-time quality sliders and instant before/after comparison previews. Whether you are optimizing hero images for faster website load times, preparing product photos for e-commerce listings, or shrinking high-resolution photography for email sharing, our compressor finds the sweet spot between file size and perceptual quality. The tool supports JPG, PNG, and modern WebP formats, and processes everything locally in your browser — meaning your personal photos, proprietary design assets, and client images never leave your device. Adjust compression strength with a granular quality slider from 1 to 100, preview the visual impact in real time, and download the optimized file with a single click. Most users achieve 60-80% file size reduction with no visible quality degradation.

Frequently Asked Questions
Which format compresses best?
WebP usually provides the highest compression ratio with minimal loss.
Can I compress images for email attachments?
Yes. Adjust the quality slider to reduce file size below common email limits (typically 25MB). Most images compress well below 1MB at 60-70% quality.
Does compression remove EXIF metadata like GPS location?
Browser-based compression typically strips EXIF data during the re-encoding process, which also protects your location privacy when sharing photos online.
What image formats can I compress?
The Image Compressor supports JPG/JPEG, PNG, and WebP formats. Each format uses optimized compression algorithms specific to its encoding method.
Is the compression lossy or lossless?
For JPG and WebP, compression is lossy with adjustable quality. For PNG, we use lossless optimization techniques that reduce file size without any quality loss.
Pro Tips & Best Practices
Balance Quality and Size
For web images, 70-80% quality produces files 60-80% smaller with virtually imperceptible visual differences to the human eye.
Compress Before Social Media
Social platforms re-compress your images anyway. Pre-compressing gives you control over the quality tradeoff instead of leaving it to algorithms.
Batch Process Entire Folders
Drag and drop your entire image folder into the uploader to compress all images at once, significantly faster than one at a time.
