Frequently Asked Questions

What image formats are supported?
JPG/JPEG, PNG, and WebP are all supported. You can also convert between formats during compression — for example, compress a PNG and save it as WebP.
How much can I reduce an image's file size?
Typically 60–90% reduction depending on the original image and quality setting. A 5 MB photo at 80% quality often compresses to under 500 KB with no visible difference.
Are my images uploaded to a server?
No. Everything happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device — complete privacy guaranteed.
What does the Max Width / Max Height setting do?
It resizes images before compressing — useful if you want to reduce large photos (e.g., 4000px wide) to a web-friendly size like 1920px while also compressing.
Can I download all compressed images at once?
Yes! After compression, click "Download All (ZIP)" to get every compressed image bundled into a single ZIP file.

Image Compressor — Reduce Image Size Online

Large image files slow down websites, fill up storage, and are frustrating to share via email or messaging. Our free image compressor reduces file size by up to 90% while maintaining excellent visual quality — entirely in your browser, with no file uploads.

💡 Compress before uploading to web

Always compress images before uploading to your website or blog. Smaller images load faster and improve SEO and user experience.

💡 Balance quality vs size

A quality setting of 70-80% usually provides a good balance between file size reduction and visual quality for photos.

💡 Compare before and after

Download and compare the compressed image side by side with the original to ensure quality meets your requirements.

💡 Compress WhatsApp photos

Photos sent via WhatsApp or Telegram are already compressed. For best results, compress from the original high-resolution source.

Image compression reduces file size through two main techniques: lossy compression (which discards some image data imperceptibly) and lossless compression (which removes redundant data without any quality loss). Our tool applies intelligent lossy compression to JPG files and lossless optimization to PNG files. The process runs entirely in your browser using the Canvas API, meaning no image data ever leaves your device. Compressed images retain their original dimensions and color profiles.
