Image Compressor
Resize, compress and download JPG, PNG and WebP images on your device.
Runs in your browser
Drop a JPG, PNG or WebP file here, or use the file picker.
Up to 12 MiB, 16 megapixels and 8192 px per edge. Output edges up to 2048 px.
PNG is lossless; the quality slider does not affect PNG output. Use resizing instead.
JPEG replaces transparency with a white background.
How it works
Choose or drop an image. Set quality for WebP/JPEG and maximum width and height for all formats. Compress to create a new output, compare file sizes and savings, then download. Small or already compressed files may become larger; the result is shown honestly. PNG is lossless; JPEG replaces transparency with white. Processing stays in your browser, with no input upload, account or server processing. Your original remains unchanged. Animation is unsupported. File and pixel limits bound mobile memory use; encoding support depends on the browser.
