Compress images to reduce file size
Compress images to reduce file size without losing quality
Supports JPG, PNG, WebP formats. Select multiple files to compress them as a batch.
The compression settings above apply to every file in the batch.
Choose multiple files in the picker and the compressor switches to a batch queue. Adjust quality, output format, and options once for the entire set, then click Compress All Files. Each row reports its own progress and finished size with the percentage saved, and offers an individual download link next to the ZIP button for the whole batch.
Balanced at 75 percent is the recommended starting point. Maximum Quality uses 90 percent for minimal compression, while Maximum Compression drops to 50 percent for the smallest possible files. The slider can fine-tune anywhere from 10 to 100 when none of the presets fit.
The picker accepts JPG, PNG, and WebP files. WebP usually produces the smallest output, JPEG suits photographs, and PNG is lossless but typically larger, which makes it best for graphics. A Progressive JPEG checkbox is available when you want images that render progressively while loading on the web.
For a single image the tool places the original and the compressed version side by side, with cards showing the size reduction percentage plus the before and after file sizes. In batch mode similar feedback appears per file, so a picture that compresses poorly is easy to spot and retry with different settings.
No. Encoding happens on a canvas in your browser and the compressed results stay in memory until you download them, so no image data is ever transmitted.
