Details
Image compression reduces the file size of photos and illustrations. Smaller files mean faster websites, lighter email attachments, and less storage usage.
Our compression engine runs entirely in your browser, so your images are never uploaded to any server. Feel free to compress sensitive photos or scanned documents.
The quality slider ranges from 0.1 to 1.0. As a guideline, use around 0.7 for social media and web, and 0.85 or higher for documents or images with fine text. The max width option resizes large images to a web-friendly size while compressing.
FAQ
How much quality will I lose?
You can adjust it with the quality slider. At 0.7-0.8, quality loss is barely noticeable for most uses. Compare the ratio and quality to find your sweet spot.
How many images can I compress at once?
There is no hard limit. However, since processing uses your browser memory, we recommend processing in batches of a few files at a time.
Are my files uploaded to a server?
No. Everything happens in your browser. Your files never leave your device.
Will my original image be deleted?
No. The compressed image is created as a new file that you download using the download button.
