Free Image Compressor & Converter — No Upload, 100% Private
Compress, resize and convert images directly in your browser. Your photos and files never leave your device — all processing happens locally using the Canvas API. No server, no account, no data sent anywhere. Free and unlimited.
Compress images without losing quality
Use the quality slider to find the perfect balance between file size and visual quality. A JPEG at 80% quality is typically 60–80% smaller than the original with almost no visible difference. Great for speeding up websites, reducing email attachments or saving storage space.
Convert between image formats
JPEG — Best for photos and complex images. Smaller file sizes, does not support transparency. PNG — Lossless quality, supports transparency. Best for logos, screenshots and graphics. WebP — Modern format supported by all major browsers. Typically 25–35% smaller than JPEG at the same quality. Ideal for web use.
Resize images
Resize by entering exact pixel dimensions or a percentage of the original. Enable Keep aspect ratio to prevent stretching. Useful for resizing profile pictures, thumbnails, product images or any image that needs to fit a specific size constraint.
Batch image compression
Switch to batch mode to process multiple images at once. Drag and drop your files, set your format, quality and resize options, and download all compressed images in one go. Saves time when preparing images for a website or photo gallery.
