Add Noise to PDF Online
Add film grain or scanner-style noise to any PDF page for a textured, vintage photographic look. 1PDF renders each page and applies a controlled random grain that you can tune with a strength value — light noise adds subtle film texture, while stronger settings mimic an old scan or grainy print. Use the seed value to lock in a specific grain pattern so you can reproduce the same result. Everything runs locally in your browser, so your document is never uploaded.

How to add Noise to PDF
- Upload the PDF you want to add grain to.
- Set the noise strength (0–100) and, if you want, a seed value so the pattern is reproducible.
- Choose a resolution, run the effect, and download the textured PDF.
Frequently asked questions
Will the text stay selectable?
No. Pages are flattened to images during the effect, so text becomes part of the picture and is no longer selectable or searchable after download.
What do strength and seed do?
Strength controls how strong the grain is. The seed chooses a specific grain pattern — the same seed and strength always produce the same noise, so you can reproduce a result.
Is the grain visible on every page?
Yes, the same strength is applied evenly to every page, which keeps the texture consistent across a multi-page document.
