Image compressor FAQ
Clear answers about privacy, formats, limits, and output.
Is my image uploaded?
No. The image is read, compressed, compared, and downloaded in your browser. Image bytes are not sent to our application or a third-party compression service.
Which image formats are supported?
The compressor supports one static JPG or JPEG, PNG, or WebP image at a time, up to 20MB. Animated PNG and WebP files are not supported.
Do I have to set a maximum file size?
No. Leave the option off to use the recommended automatic settings, or enable it when a website or form requires a particular limit.
How do I compress an image to 20KB, 50KB, 100KB, or 200KB?
To compress an image to 20KB, 50KB, 100KB, or 200KB, enable Set a maximum file size, enter the KB value, and run the compressor. The tool returns the highest-quality tested result under that limit when possible.
How do I compress an image to 1MB or 2MB?
Enable Set a maximum file size, choose MB, and enter 1 or 2. The compressor searches for a result under the selected limit when possible.
Can I compress an image without losing quality?
Compression involves a file-size and quality tradeoff. Automatic settings aim to reduce noticeable visual changes, but the tool cannot guarantee pixel-level lossless compression. Smaller targets can produce more visible changes.
Can every target file size be reached?
Not always. If changing encoding quality is not enough, the compressor returns the smallest tested result and suggests using the Image Editor to reduce pixel dimensions.
Does compression change the image dimensions?
No. The output keeps the original width and height. Use the Image Editor when you need to crop, resize, or change aspect ratio.
Does the compressor preserve transparency?
Yes. PNG and WebP outputs keep transparent areas, although color and detail may change as the file is compressed.
Is the image compressor free?
Yes. The browser compressor is free to use, requires no account, and adds no watermark.
