About image compression
How do quality and output format work?
Add your images, set quality and output format, then choose Compress images. Lower quality can make JPG and WebP files smaller, with some loss of detail. PNG is lossless, so the quality slider does not affect PNG output. To try different settings, adjust the controls and choose Compress images again. Your selected originals stay in the queue.
What if the compressed file is larger?
Some images are already well compressed. If the new file is the same size or larger, this tool keeps the original file and its format. The results show the original size, output size and savings before you download.
Are there file-size limits?
There is no server upload limit. Large images and batches are limited by your browser's memory and the image formats it can decode. Try fewer or smaller files if your device runs out of memory.
Why compress images in your browser?
Smaller images use less bandwidth and can help web pages load faster. Compression happens on your device, so your original files are not sent to a remote server or modified. You can download each result or save the batch as a ZIP.
