From document objects to page pixels
A normal PDF can contain text glyphs, vector paths, images, layers and interactive objects. A rasterized copy replaces that structure with a page-sized image while preserving the source page dimensions.
The result usually looks similar at its intended viewing size, but text is no longer selectable and vector artwork no longer scales indefinitely.
What becomes flattened
Visible form appearances, annotations and layered artwork are captured in the rendered page image. Links, form controls, tags, reading order and other interactive or accessibility structures are not preserved as live objects.
Rasterization is therefore stronger than flattening only form fields. Choose the narrower operation when you need to keep searchable text or links.
When rasterization is useful
Common uses include creating a viewer-compatible delivery copy, fixing the visible state of complex artwork, reducing dependency on unusual fonts and producing a page image before a later OCR workflow.
It is not encryption, redaction or proof against editing. Preserve the original and use purpose-built security tools for sensitive information.
Preserve signed and authoritative originals
Rebuilding a PDF changes its bytes and invalidates existing digital signatures. Keep signed or archival originals unchanged and label rasterized files as derivative copies.
Always review the result at normal zoom and at a magnified detail level before delivery.
Put the workflow into practice
Arrange source documents, select the pages you need, and create one PDF locally in your browser. Review the result before choosing any optional next step.

Clear answers before you merge
Does rasterizing a PDF make it read-only?
It removes live page objects, but it is not encryption and does not prevent someone from editing or replacing the page image.
Will searchable text remain?
No. Text becomes pixels unless OCR is applied to the rasterized output afterward.
Does it flatten PDF forms?
Yes. Visible field appearances become part of the page image and the fields are no longer interactive.
Is rasterization the same as redaction?
No. Use a dedicated redaction workflow to remove sensitive content rather than relying on visual flattening.
