Compress JPEG, PNG, and WebP images in your browser. Adjust quality, resize, convert formats, and download the result without uploading anything.
Decoding and compression run in your browser. Your photos are never uploaded.
Tune JPEG/WebP quality, set a maximum width or height, or convert between JPEG, PNG, and WebP.
See both images side by side with exact file sizes and the percentage saved.
Converting a transparent image to JPEG fills the background with white, and the tool tells you first.
When you use Image Compressor, your data never leaves your browser. All transformations execute in-memory on your local machine with zero server uploads. Web assets are downloaded to run the tool, but your input data is never transmitted.
No. The image is read, decoded, and re-encoded by your browser. Nothing is sent to YoussefLabs servers.
PNG is a lossless format, so browsers ignore a quality setting for it. To make a PNG smaller, resize it or convert it to WebP or JPEG.
Exported images are re-encoded through the browser and may not retain EXIF metadata such as camera model or location. Photo orientation is applied to the pixels so images are not rotated incorrectly.
Files up to 50 MB and up to 64 megapixels (16384 px per side) are supported to avoid running out of browser memory. Animated GIF, PNG, and WebP files are not supported.
Change the width and height of a JPEG, PNG, or WebP image in your browser. Keep the aspect ratio or set exact pixels, then download the result.
Convert images between JPEG, PNG, and WebP in your browser. Choose the output format and download the converted file without uploading anything.
