Choose the right compression level
Pick a preset (light, balanced, or maximum) or tweak the advanced options to get the size reduction you want. Everything runs locally, so sensitive PDFs never hit a server and your results are ready immediately.
Need to do more? Rotate, split, merge, or convert the same file without re-uploading — just use the controls in the preview.
