Frequently asked questions
- Does grayscale conversion reduce file size?
- Yes, often significantly. Removing color data from embedded images reduces the overall file size, especially for image-heavy documents. Processing runs entirely on your local server.
- Is the conversion reversible?
- No. Once converted to grayscale, the original color information is removed. SnapOtter creates a new file so your original color PDF is preserved. Files stay on your own network.
- Will text remain sharp after conversion?
- Yes. Text is converted to black and remains crisp and fully searchable. Only the color values change, not the rendering quality. All processing happens on your self-hosted instance.
