Free browser-based compression tools
Compress
Compress JPG, PNG, WebP, and upload-ready images to smaller file sizes. Choose a general image compressor, a format-specific compressor, or a preset KB target for forms, websites, email, and document uploads.
Choose the right compressor
JPG is usually best for photos, portraits, product images, and camera uploads.
PNG is best for screenshots, graphics, transparent images, and sharp edges.
WebP is useful for websites, blogs, ecommerce, and CMS images that need smaller files.
Image Compression Tools for Exact KB Upload Limits
Some upload forms ask for a strict file size such as 50KB, 100KB, 200KB, 500KB, or 1MB. This compress hub links the tools that reduce image file size, preview the result, and help you download an upload-ready image without sending personal files to a server during normal processing.
Start with Image Compressor for mixed JPG, PNG, and WebP files. Use Compress JPG or Compress PNG when you already know the output format your form or website requires.
Tested as a compression tool collection

Private by default
The compression tools are designed to run locally in your browser. That means personal photos, screenshots, signatures, and documents do not need to be uploaded to our server for normal compression.
