Questions about image compressor
Will the quality drop?
JPG and WebP use lossy compression, so pick a quality that still looks good — 70% is a sensible start.
Can I compress many at once?
Yes. Add several images and they download together as a ZIP.
Are my images uploaded?
No. Compression happens in your browser.
Compress without ruining the picture
Images are usually the heaviest part of a web page or email. Compressing JPG, PNG and WebP files can cut their size by half or more with little visible difference, which means faster websites, quicker uploads and attachments that fit inside mail limits.
For photographs, a quality of 70 to 80 percent is the sweet spot: the file shrinks dramatically while the picture still looks sharp. For screenshots, logos and graphics with flat colour, PNG compression reduces the number of colours in a controlled way, which saves a lot of space without visible banding in most cases.
Tips
Work from your original every time, because re-compressing an already compressed JPG loses quality each round. If a file cannot be made smaller, the tool keeps your original so you never get a bigger result. Limiting the width to the size at which the image is actually displayed often saves more than any quality setting.
You can add many images at once, and they are processed in parallel on your device. Nothing is uploaded.
