PNG is lossless, so quality doesn’t apply. Use Resize to make files smaller, or choose WebP.
More options
Your browser can’t create WebP files, so WebP is unavailable. Try a current version of Chrome, Edge or Firefox.
How it works
Three simple steps.
- 1
Add your images
Drop up to 30 JPG, PNG or WebP images, or paste from your clipboard.
- 2
Dial in the size
Drag the quality slider and watch each file size update live. Switching to WebP usually saves the most.
- 3
Compare and download
Check quality with the before/after slider, then download files or a ZIP.
How accurate are the file sizes shown?
While you drag the quality slider, sizes marked ≈ are fast estimates. A moment after you stop, each image is compressed for real and the exact size replaces the estimate. Downloads always use your current settings.
How much can I reduce an image’s file size?
It depends on the image. Large photos saved at high quality often shrink a lot, while images that are already optimised may not get smaller. If compression would make a file bigger, the tool keeps your original.
What is the best format for small file sizes?
WebP generally produces smaller files than JPG or PNG at similar visual quality, and it is supported by all major modern browsers.
Why doesn’t PNG get much smaller?
PNG is a lossless format, so it cannot throw away detail the way JPG and WebP can. For photos, converting a PNG to WebP or JPG usually saves far more space.
Will compressing images help my website speed?
Usually, yes. Smaller images load faster, which helps page speed and Core Web Vitals such as Largest Contentful Paint, especially on mobile.
Are my images uploaded?
No. Compression runs locally in your browser. Your images are never uploaded.
