Frequently Asked Questions
Does this tool upload my images anywhere?
No. All compression happens entirely in your browser using the Canvas API. Your images are never sent to a server, stored, or transmitted anywhere.
What image formats are supported?
JPEG and PNG. JPEG quality is adjustable via the slider. PNG output size is determined by the browser's built-in compression — there is no quality setting for PNG.
How much can I reduce an image's file size?
Typically 40–80% for JPEG images at quality 80. Results vary by image content. Photos compress well; images with large flat areas of colour may see less reduction.
Will compressing reduce the image dimensions?
No. Only the file size is reduced. The output image has the same pixel dimensions as the original.
