Compress images to the exact size you need — in your browser
Hit a KB target or dial the quality yourself. Nothing uploads.
Hit a KB target or dial the quality yourself. Nothing uploads.
Most image compressors ask you to pick a quality percentage and then hope. But the requirement is rarely a quality level — it is a hard ceiling. A job application that will not accept a photo over 500 KB, a forum with a 2 MB limit, a form that silently fails on anything larger. Guessing at quality settings until the file happens to fit is the wrong shape of tool for that problem.
SlimFit takes the target size directly. Tell it the number of kilobytes you need to be under and it works out the compression required to land there, locally, inside the browser tab. Nothing is uploaded.
You can also resize while compressing. Dropping the pixel dimensions is often the single biggest saving available, and for an image that will only ever be viewed on a screen it usually costs nothing visible.
You are in control. Quality mode lets you pick the exact level; target-size mode uses whatever compression is needed to reach the size you asked for, so a very aggressive target will show.
Compression strips EXIF metadata as part of the process — which also removes the GPS coordinates that photos often carry.
Batches of up to five are free, target-size mode included. A one-time purchase removes the limit.
