What is the Image Compressor tool?
Large images slow down websites, fill phone storage and fail upload limits. This compressor re-encodes images with an adjustable quality level and shows the size saved for each file, so you can find the perfect balance between size and clarity.
How to use Image Compressor
- Drop images.
- Adjust the quality slider.
- Compare sizes.
- Download individually or as ZIP.

- Speed up websites and improve SEO
- Save storage and data

Tips for the best results
- Start from the largest, sharpest original you have — compressing an already tiny photo reduces quality.
- Crop unnecessary background before resizing so the subject stays clear.
- Check the final KB and pixel size shown under each file before uploading to a portal.

Key features
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this Image Compressor converter processes everything on your own device using the HTML5 Canvas API with an adaptive compression algorithm. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
