Smaller files, same picture

Most images on the web are 2–10× larger than they need to be. Compression removes that excess with a quality slider you control. Typical photos shrink 60–90% with no visible difference at quality 80. Batch mode processes up to 30 files at once and delivers everything in a single ZIP.

Need to hit a hard limit like "under 100 KB" for a form? The target-size compressor binary-searches quality levels until the file fits, and tells you honestly if it had to reduce resolution.

Frequently asked questions

Does compression reduce image quality?

At quality 75–85 the difference is invisible on screens. The tool shows before/after sizes so you can judge each file yourself before downloading.

Can I compress images in bulk?

Yes: up to 30 files per batch, processed in parallel in web workers, downloaded as one ZIP.
