FAQ
Is this image compressor free to use?
Yes, this tool is completely free to use with no limits on how often you can use it.
Do my images get uploaded to a server?
No. All resizing and compression happens entirely in your browser using the Canvas API. Your images are never uploaded anywhere — they never leave your device.
Why doesn't the quality slider affect my PNG image?
PNG is a lossless format, so browsers ignore quality settings for it. To keep the quality slider useful, PNG uploads are automatically converted to JPEG in the result — JPEG and WebP uploads keep their original format.
