How It Works

1

Upload Your Image and Set Quality Level

Drag and drop or browse to select any PNG, JPG, or WebP image from your device. Use the quality slider to choose how aggressively the compressor should reduce file size — lower percentages yield smaller files while higher percentages preserve finer details like text sharpness and gradient smoothness.

2

Browser-Side Compression Engine

The tool re-encodes your image using optimized quantization tables and chroma subsampling, all within the browser using the HTML5 Canvas API. It strips unnecessary metadata like EXIF camera data and GPS coordinates, which alone can save kilobytes without touching a single pixel of visual content.

3

Compare and Download the Result

A side-by-side preview shows your original and compressed image so you can visually confirm that quality remains acceptable. The tool displays the exact byte savings and percentage reduction, letting you download the compressed file only when you are satisfied with the balance between size and clarity.

Frequently Asked Questions

How much file size reduction can I expect?
Results vary by image type, but photographs typically compress 40–70% at the 70% quality setting with no visible degradation. Images with large flat color areas, like screenshots or logos, can compress over 80% because chroma subsampling removes redundant color information efficiently.
Will compressing an image multiple times degrade it further?
Yes. JPEG is a lossy format, so each recompression discards additional data. Always compress from the original file rather than re-compressing an already-compressed image to avoid cumulative quality loss known as generation degradation.
Does the compressor support batch processing?
The current version processes one image at a time to give you precise control over quality settings per file. For large batches, you can quickly process each image individually and download results as you go.
