Compress and resize images online
Shrink JPG, PNG and WebP images by quality or to a target size in KB, and resize them by percentage, exact pixels or ready-made sizes for Instagram, YouTube, X and Facebook. Batch process in your browser — nothing is uploaded.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Compress by quality or by size
Pick a quality level, or set a target such as 200 KB or 2 MB and let the tool find the best quality that fits. The list shows the original and new size with the percentage saved.
Resize to the exact pixels you need
Scale by percentage, enter width and height, or choose a preset for Instagram, YouTube, X or Facebook. Crop fills the frame; Fit keeps the whole image on a background colour.
FAQ
Which format compresses best?
WebP gives the smallest files; JPG is the most compatible for photos. PNG stays lossless, so it shrinks mainly through resizing.
Does resizing reduce quality?
Downscaling keeps images sharp; upscaling can’t add detail.
Is it free?
Yes, with no limits on the number of images.
