FAQ
- Is my PDF uploaded to a server?
- No. Compression happens entirely in your browser — your file never leaves your device.
- Why did my text stop being selectable after compressing?
- To shrink the file, each page is re-encoded as an image, so text becomes part of the image. This gives big savings on scanned or image-heavy PDFs, but the compressed copy is no longer selectable text.
- How much smaller will my PDF get?
- It depends on the PDF and the level you choose. Scanned and image-heavy PDFs often shrink dramatically; PDFs that are already small or mostly plain text may save little.
