Image Compression Tools
Make images smaller without making them bad. Choose a quality level, or name the exact file size you have to fit under and let the compressor find the best result below it.
Images are processed on your device and never uploaded.
Two ways to compress
By quality — you pick how much fidelity to keep and the file size comes out wherever it lands. Use this when you want a smaller file and have no hard limit.
By target size — you name a ceiling in KB or MB and the tool searches for the highest quality that stays underneath it. Use this when a form, portal or platform imposes a limit.
Which format should the output be?
- JPG — photographs, universal compatibility, no transparency.
- WebP — 25–35% smaller than JPEG at the same quality, keeps transparency, read by every current browser.
- PNG — lossless and transparent, but enormous for photographs. Compressed here by palette reduction rather than a quality slider.
Compress or resize?
Compression changes the bytes; resizing changes the pixels. For web images you usually want both — resize to the size the layout actually displays, then compress. In that order the result is noticeably better than compressing a huge image.
Nothing is uploaded
Every compressor on this page decodes, re-encodes and measures the file inside your browser. There is no upload endpoint for these tools, so your photos are never transmitted anywhere.
