COMMON QUESTIONS
Image Compressor FAQ
How can I compress an image without uploading it?
Choose the image in this tool and select Compress images. The browser decodes and re-encodes it locally; the file is not sent to our server.
Why can a compressed image become larger?
A small or already optimized image may grow after re-encoding. Try a lower quality or WebP output, and keep the original whenever it is smaller.
Does compression remove image metadata?
Yes. Re-encoding through the browser canvas normally removes EXIF and other embedded metadata, which can also reduce file size.
