HOW THIS TOOL WORKS
COMPRESS IMAGES ONLINE
EXPLAINED.
Compress JPG, PNG and WebP images locally in your browser. Adjust quality and download smaller files without uploading them.
Image operations begin by decoding the source into pixels, applying the requested resize, crop, compression or format rules, and then encoding a new file. Transparent pixels are preserved by formats such as PNG and WebP but are flattened onto white when JPG is selected. Vector SVG input is rasterized at its decoded dimensions, and animated input is exported as a still frame unless the selected tool explicitly creates an animated format.
For dependable results, start with a valid source file, confirm the preview or status message, and open the downloaded copy before replacing the original. Large page counts, very high-resolution images and complex documents require more device memory and may take longer than small files, even though the controls and output steps remain the same.
