Local PDF page normalizer
Choose a target paper size and decide whether to scale with padding, scale with cropping, or change only the page canvas. Aftermath creates a separate local PDF so the source remains untouched.
Choose one flat PDF to inspect its page geometry, normalize a separate copy to A4 or Letter, review common document metadata, or flag probably blank pages before you explicitly remove them from a new download. JavaScript activates the local diagnostic workspace on this page.
Scale with padding keeps all visible content and leaves margins. Scale with crop fills the target page but can trim edges. Change canvas only adjusts the page boundary without scaling content, which can leave content outside the visible target area. The workspace labels each result before export.
Open the page-size inspector when you need to understand a mixed document first. The normalizer is for flat, readable PDFs and intentionally rejects encrypted, signed, or interactive-form documents rather than creating an unsafe copy.
Questions people ask
No. It changes page geometry and may scale existing content. It cannot add detail to raster images or scanned text inside a PDF.
Use padding to preserve every edge, crop when edge trimming is acceptable, and canvas-only only when you understand how a viewer or printer will handle content outside the new page boundary.
No. Aftermath downloads a separate normalized copy and leaves the selected source file unchanged.
