Why compress your images?
Large image files slow down your website, eat into email attachment limits, and take longer to share. Compressing reduces the file size while keeping the image visually sharp, which is especially useful before uploading to a website, CMS, or social media.
This tool uses your browser's built-in Canvas engine to re-encode the image at a lower quality setting โ your photo is never sent to a server, so it stays completely private.
Frequently asked questions
Is my image uploaded to a server?+
No. Compression happens locally in your browser using the Canvas API. Your image never leaves your device.
Will compressing reduce the image quality?+
Some quality is traded for a smaller file size, but at 70-80% quality most photos look nearly identical to the original while being significantly smaller.
What file formats are supported?+
JPG, PNG, and WebP images can be uploaded, and the compressed result is downloaded as a JPG for the smallest file size.
Is there a file size limit?+
No fixed limit, though very large images may take a few extra seconds to process depending on your device.
