Can I compress multiple images at once?
Yes. You can upload multiple JPG, PNG, or WEBP files and download all compressed versions together as a ZIP archive.
Which image formats are supported?
This tool supports JPG, PNG, and WEBP images — the most common web and photography formats. All are processed locally in your browser.

More About Image Compression
How much can I compress my images?
Depending on the compression level you choose, file sizes can be reduced by 30% to 70% or more. The medium setting typically offers the best balance between quality and size reduction.
What is the difference between lossy and lossless compression?
Lossy compression permanently removes some image data to achieve smaller files, though the visual difference is often unnoticeable. Lossless compression reduces file size without discarding any data, preserving the original quality exactly. This tool uses lossy compression with adjustable quality levels.
Which image formats are supported?
This compressor supports JPG, PNG, and WEBP — the three most common image formats used on the web. All processing happens locally in your browser with no uploads required.
Is image quality preserved after compression?
Yes. Even at medium compression, the visual difference is nearly invisible to the human eye. The "Keep original quality" setting applies minimal compression, while higher levels prioritize smaller file sizes with only slight quality trade-offs.
Is there a maximum file size I can compress?
There is no hard file size limit since all compression runs in your browser. Very large images (above 50 megapixels) may process more slowly depending on your device, but typical photos and web graphics compress instantly.
