Frequently asked questions
- Which file formats are supported?
- The tool supports PNG, JPG/JPEG and PDF files. File type is verified by the real file signature, not only by extension.
- How long are uploaded files stored?
- Compressed outputs are stored temporarily and are removed by the cleanup process after 24 hours.
- Is PDF compression real?
- Yes. PDF files are rewritten on the server with Ghostscript so images, fonts and PDF streams can be optimized.
- How are risky uploads handled?
- File signatures and active PDF content are checked. When ClamAV is available on the server, uploads are also scanned before compression.
