Is there a watermark or size limit?

No watermark. Typical uploads up to ~200 MB (depends on server limits).

Will text stay searchable?

Yes. This compressor optimizes images and structure; text and vectors remain searchable. (Only a 'flatten to images' mode would rasterize text.)

Which preset should I choose?

Smallest for maximum shrink (may reduce image quality), Good for balance, High Quality for best visuals but larger file size.

Files are processed in memory and the output is offered for download; temporary files are deleted after send.
