Are my images uploaded anywhere?
No. Compression runs entirely in your browser, so your photos never leave your device. Once the page has loaded, the tool still works with your internet turned off.
Which file types can I compress?
JPG, PNG and WebP. Other types, such as GIF, HEIC or SVG, are skipped and the tool tells you which files were left out.
How does the File size (KB) option work?
You type the size you want, for example 200. The tool finds the highest quality that fits. If even the lowest quality is too big, it also reduces the dimensions. An image that is already under your target is kept as it is.
Which format gives the smallest file?
For photos, WebP and JPG are usually much smaller than PNG. Use PNG when you need lossless output or sharp graphics. You can choose the format in the Save as menu.
Why did my file not get smaller?
Images that are already well optimised can grow when they are saved again. In that case the tool keeps your original file and says so. If you change the format, a larger result is flagged so you can pick a smaller target or another format.
Does PNG use the quality setting?
No. PNG is lossless, so there is no quality to lower. To make a PNG smaller, the tool reduces its dimensions, or you can set a width yourself.
Is transparency kept?
PNG and WebP keep transparent areas. JPG cannot store transparency, so those areas become white.
Is my camera or location information removed?
When the tool saves a new copy, information stored inside the file, such as camera details and GPS location, is not carried over. If your original is kept because it is already small enough, that file is unchanged.
How many images can I add at once?
Up to 100 images at a time. Very large photos, tens of megapixels, may be too big for the browser on some phones.The tool tells you when an image cannot be processed.
