Perfect for preparing images for social media, email attachments, or web design.

  • Scale image width and height smoothly while locking the aspect ratio
  • Fine-tune file sizes using the adjustable compression quality slider
  • Broad format support including JPG, PNG, WebP, and BMP
  • Guaranteed privacy: Your images are processed exclusively in your device's RAM
  • Instantly see your exact file size reduction percentage before saving

🔒 All calculations are performed locally on your device. No data is sent to any server.

❓ Frequently Asked Questions

What image formats are supported?▾
This tool supports JPG/JPEG, PNG, WebP, and BMP formats. You can upload any of these formats and the compressed output will maintain the same format.
What is the best quality setting for web images?▾
For web use, a quality setting of 70-80% typically provides the best balance between file size and visual quality. Most viewers cannot distinguish between 80% and 100% quality, but the file size difference can be 60-70%.
Are my photos uploaded to the cloud?▾
No. All image processing happens entirely within your browser's memory using the HTML5 Canvas API. Your photos are never uploaded to any server, making this tool completely safe for private or sensitive images.
