Frequently Asked Questions
Will the file size decrease?
It depends. Removing color information can reduce file size in some cases, but because the output is image-based the result may be similar in size or occasionally larger depending on the original content.
Is text still selectable?
No. The grayscale output is image-based, so text will not be selectable or searchable in the resulting PDF. Each page is rendered as a grayscale image.
What resolution is the output?
Pages are rendered at a high resolution suitable for printing and on-screen viewing. The output maintains the visual quality of the original document.
Is my file uploaded to a server?
No. Everything runs locally in your browser. Your file never leaves your device — no uploads, no cloud processing.
