Frequently asked questions
Are my files uploaded?
No. Every tool in this category runs inside your browser on your own device. Files are never sent to our servers, and nothing is stored after you close the page.
Why did my file barely shrink?
Text-only PDFs and Office files are already compressed. Big savings come from photos and scans inside the file.
Will quality suffer?
Each tool offers levels. The recommended level is chosen to be hard to tell apart from the original on screen.
