Make files smaller. When a limit is fixed for you — “under 200 KB” — target-size mode works down to that line.
How to use it
- Upload one or more images.
- Choose target size when a limit is fixed, or quality when you just want it smaller.
- Pick the output format. WebP is usually 30–40% smaller than JPG at the same quality.
- Run it and compare before and after, then download.
How does target size work?
The encoder searches for the quality setting that lands just under your limit. If quality would have to fall below a usable floor, it reduces the resolution instead and tells you it did — a smaller clean image beats a large smeared one.
Why can't PNG hit a target size?
PNG is lossless and has no quality dial to turn, so file size cannot be steered. When you ask for a target size we switch the output to JPG and say so.
How do I reduce size without losing quality?
Convert to WebP. At the same visual quality it is typically 30–40% smaller than JPG. If the image must stay lossless, resize it smaller instead — that is the only honest way to cut bytes without touching quality.
WebP or JPG?
WebP for anything going on the web, and it also keeps transparency. Choose JPG when the file has to open in old software or be accepted by a system that only takes JPG.
Can I compress several at once?
Yes. Upload as many as you like; the same setting applies to all of them and you can download them together.
