About Image Compressor
Image Compressor is a free online image tool that lets you compress jpeg, png & webp images locally — no upload, fully private without uploading files to any server. Designers, photographers, bloggers, and social media managers rely on browser-based image tools to make quick edits without launching heavy desktop software. Your images never leave your device — all processing happens locally using modern browser APIs.
How to Use
1
Drop or select your image
Drag a JPEG, PNG, or WebP file onto the drop zone, or click it to open the file browser.
2
Adjust quality and format
Use the quality slider (1–100%) and choose the output format. Higher quality = larger file size.
3
Compress and download
Click "Compress" to process the image in your browser. Click "Download" to save the result.
💡 A quality of 75–85% gives a great balance between file size reduction and visual quality for most images.
Frequently Asked Questions
You can compress JPEG, PNG, and WebP images. The output format can be set to the same as the input, or converted to JPEG, PNG, or WebP independently using the format selector.
No. This tool performs quality-based compression only — the image width and height remain the same. Only the file size changes based on the quality level you select. If you need to resize, you would need a separate resizing tool.
Absolutely not. All processing happens entirely within your browser using the HTML5 Canvas API. Your images never leave your device — no data is sent to any server. This tool works completely offline once the page has loaded.
For photos and complex images, 75–85% is an excellent balance — typically 40–70% file size reduction with barely perceptible quality loss. For simple graphics or images with flat colors, PNG output at 80–90% may be better. For maximum compression (thumbnails, previews), you can go down to 50–65%.
This tool supports all major web image formats including PNG, JPEG/JPG, WebP, GIF, SVG, ICO, BMP, and TIFF. The Canvas API used for processing handles these formats natively in your browser without any plugins or extensions required.
