Compress Image

Compressing an image shrinks its file size so it sends faster and fits upload limits, while keeping it looking the same at normal viewing sizes. Photos straight from a phone are often 3–8 MB; most of that weight is detail no screen ever shows. Pick a compression level, add up to 20 images, and download the smaller files — or a zip when there are several. Everything is re-encoded inside your browser, so your pictures are never uploaded. If a file is already well compressed, the tool keeps your original rather than making it worse.

How to use it

1. Add your JPG, PNG or WebP images — up to 20 at once.
2. Choose a compression level: light, balanced, or strong.
3. Compress, then download the image or the zip. The note tells you exactly how much smaller the files got.

Examples

• A 4.2 MB phone photo becomes about 900 KB at the balanced setting.
• Ten listing photos compress in one batch and download as a single zip.

Frequently asked questions

Will compressing reduce my image quality?

Slightly, by design — compression works by discarding detail too fine to notice at normal size. At the light and balanced settings the difference is rarely visible on screens. Choose strong when small size matters more than close-up sharpness, and avoid recompressing the same file repeatedly, because the losses add up.

Why did my file not get smaller?

It was already efficiently compressed — common for images exported by apps or downloaded from the web. When re-encoding would make a file larger, this tool keeps your original bytes untouched and says so in the result, rather than handing back a worse file.

Which formats are supported?

JPG, PNG and WebP, detected by the file's actual content rather than its name. JPG and WebP respond well to the quality setting. PNG is lossless, so its savings are smaller — if you need a PNG dramatically smaller, converting it to WebP with the Convert Image tool usually helps more.

Are my images uploaded to a server?

No. Decoding and re-encoding happen entirely inside your browser using its built-in image engine, so the pictures never leave your device. That is also why there is no waiting for uploads — compression starts instantly.
