Compress Images Free Online
Free, unlimited image compressor — reduce JPG, PNG, WebP and HEIC file sizes privately in your browser, no upload needed. Adjustable quality, batch support.
Photos straight from a phone or camera can be quite large, which slows down websites and makes them harder to email or upload. This tool reduces the file size of JPG, PNG, WebP and HEIC images while keeping them looking good. Use the quality slider to control how aggressively each image is compressed, and process several images at once. As with everything here, the compression happens on your own device.
Frequently Asked Questions
Will compression noticeably reduce image quality?
At the default 75% quality setting the difference is hard to see. Dragging the slider lower gives smaller files at the cost of some visible quality loss.
Which formats can be compressed?
JPG, PNG, WebP and HEIC images are all supported as input. Output can be saved as JPEG or WebP.
Can I compress many images at once?
Yes, batch compression is supported for multiple images.
Why would I need to compress an image?
Smaller images load faster on websites and are easier to email or upload where there are size limits.
