About this tool
Image Compressor reduces the file size of photos and graphics so pages load faster and uploads finish sooner. A live preview shows the effect of the quality slider so you can balance clarity and bandwidth savings without guesswork.
Features
Support for PNG, JPEG, and WebP, adjustable quality, before-and-after file size comparison, batch uploads, and one-click download. The tool uses browser APIs to avoid expensive server round-trips.
Use cases
Preparing hero images for websites, shrinking attachments before sending by email, optimising product photos for e-commerce stores, and reducing the size of screenshots added to bug reports.
Why choose this tool
All compression happens locally, so confidential mockups and personal photos stay on your device. The visual comparison makes it easy to pick the sweet spot between quality and size for every asset.
FAQ
- Is the compression lossy?
- JPEG and WebP use lossy compression controlled by the quality slider, while PNG uses lossless optimisation.
- How much smaller can files become?
- Photos typically shrink by 50 to 80 percent with minimal visible quality loss when the slider is set to around 80.
- Are original files modified?
- No. The tool creates a new compressed copy and leaves the source file untouched on your drive.
