Image Compressor
Re-encodes an image as JPEG or WebP at the quality you choose. Shows the original size, the new size and the saving, then downloads it. Nothing is uploaded.
Frequently asked questions
Will a PNG keep transparency?
Not as JPEG: transparent areas become white. WebP can keep transparency.
Why did the file get bigger?
If the original was already well compressed, re-encoding at a high quality can add bytes. Lower the quality, or resize the image first.
Is the file uploaded?
No. Compression runs in this browser tab.
