Result

Are you familiar with the situation when the site does not allow you to upload a photo, because its file weighs more than 2 megabytes, and you do not have special programs for compressing images at hand?

Our local image compressor will solve this problem in a moment completely confidentially. Because compression happens in your browser using the Canvas API, your private photos are not shared over the network.

You can flexibly adjust the quality level using a convenient slider and immediately see the final file size and quality on the preview. Batch compression of multiple photos is also available.
