Frequently asked questions
How does the image compressor work?
It re-encodes your PNG, JPG, or WebP images to reduce file size while preserving visual quality, using compression that runs entirely in your browser.
Will compression reduce my image quality?
The tool targets a strong balance between size and quality, and for most images the difference is not visible. You can compare the result before downloading.
Is the image compressor private?
No. All compression happens locally in your browser, so your images stay private and are never sent to a server.
Why did my PNG barely get smaller?
PNG is a lossless format, so the quality slider has little effect on it. For photos, convert the PNG to WebP or JPG instead — lossy formats shrink photographic images far more.
