How do I reduce an image's file size without visible quality loss?

Open Compress Image on Tools-Bench, add one or more photos and keep the quality near 0.8. Each image is re-encoded inside your browser and shows its size before and after; photos often shrink 60–90% with no visible difference. PNGs are saved as WebP, which keeps transparency. Nothing is uploaded, and it's free.

About Compress Image

Image compression re-encodes a photo at a lower quality setting so the file gets dramatically smaller while still looking sharp on screen. A 5 MB phone photo often shrinks to a few hundred kilobytes with no visible difference — which means faster websites, emails that actually send, and uploads that fit under size limits.

How to use Compress Image

1
Add your images
Drop in JPG, PNG or WebP files — several at once if you like.
2
Set the quality
0.8 is a great default: big savings, no visible loss. Go lower for maximum savings, higher for print-quality output.
3
Compress and download
Each image shows its before/after size. Download individually or grab everything at once.

Frequently asked questions

Are my photos uploaded anywhere?
No. Images are processed by your browser's own canvas engine, entirely on your device. Nothing is uploaded, stored or seen by anyone else.
How much smaller will my images get?
Typically 60–90% smaller for photos, depending on the source and the quality you choose. PNG screenshots compress less than photographs.
Will the image lose quality?
At quality 0.8 the difference is invisible in normal viewing. Compression artifacts only become noticeable at very low settings.
How do I compress an image to under 100 KB?
There's no target-size setting, so work in two steps: lower the quality (try 0.6) and check the size shown under each image. If it's still too big, shrink the pixel dimensions with Resize Image first — halving the width and height cuts the file to roughly a quarter.
