Smart Compression Tips
For Web
Medium-to-high quality is often enough for websites. WebP can reduce size on supported browsers.
For Email
Keep images under 1MB. 70% quality usually works great for email attachments.
For Print
Use 90-100% quality and maintain original dimensions for print-ready images.
For Mobile
Lower quality settings can be useful for mobile previews and quick uploads.

Quality control
Use the quality slider to balance image clarity and file size. For official forms, always preview the result before uploading it.
This tool is useful for everyday image compression tasks without creating an account.
