What the free plan actually gives you
Upload, it compresses, you download. No account, no watermark, no file count for the day — only a per-batch limit of 20 files and 5 MB each. In practice that covers every image on a blog post.
The free API quota is small (a few hundred compressions a month) and metered separately, so automated pipelines need a paid plan. The compression itself is lossy but visually careful, which is why the output is consistently smaller than most competitors at the same quality.
Where it breaks
- 20-file batch limit on the web tool
- 5 MB per file caps large screenshots
- API quota is small on the free tier
What we would use instead
If the limits above are a problem, the closest free substitutes are Remove.bg and PDF24 Tools. They are not identical — each one trades something different — but all of them let you finish a job without paying.

Questions people actually ask
Is there a daily limit?
No daily cap on the web tool. The limit is 20 files per batch and 5 MB per file.
Does it remove metadata?
Yes, EXIF and colour profiles are stripped, which is part of why the files get so much smaller.
Is the compression lossy?
Yes, but visually near-identical at default settings. Use it for web delivery, not for archival masters.
